Part 1: Sampling plan for batch inspection based on acceptance quality limit (AQL) (ISO2859-1:1999, IDT: replaces GB/T2828-1987)
Part 2: Sampling inspection procedures and sampling tables for isolated batches by attributes (corresponding to ISO2859-2; replacing GB/T15239-1994) - Part 3: Sampling inspection procedures for skip batches by attributes (corresponding to ISO2859-3: replacing GB/T13263-1991) Part 4: Evaluation procedures for claimed quality levels (corresponding to ISO2859-4; replacing GB/T14437-1997, GB/T14162-1993)
Part 10: Introduction to sampling systems by attributes (corresponding to ISO2859-10) This part is GB/ Part 1 of T2828
This part of GB/T2828 is equivalent to the international standard ISO2859-1:1999 "Sampling procedures for inspection by attributes Part 1: Sampling plans for batch inspection based on acceptance quality limit (AQL)" and the technical amendment 1 to ISO2859-1:1999 issued by ISO on March 1, 2003. At the same time, the following corrections are made to the errors in the text of ISO2859-1:1999: - The curve with Ac=4 in Table 9 is removed:
In the curve with Ac=9 in Table 9, the arrow is removed; - In the curve with Ac=7 in Table 9, the arrow position is moved from 3 to 3.15; In the curves with Ac=27, Ac=30, Ac=41.Ac=44 in Table 9, the horizontal axis is changed to n multiplied by the number of unqualified products per hundred units.
This part replaces GB/T2828-1987 "Batch inspection by counting sampling procedures and sampling tables (applicable to the inspection of continuous batches)" from the date of implementation. Compared with GB/T2828-1987, the changes in the technical content of this part mainly include: changing the qualified quality level (AQL) to the acceptance quality limit (AQL); adding the content that can be used for isolated batch inspection (see 1.2); changing the transfer rules from normal inspection to relaxed inspection: allowing skip batch sampling to replace relaxed inspection if the relevant requirements are met (see 9.5); eliminating the gap between the acceptance number and the rejection number of the special wide inspection and relaxation scheme included in the relaxed inspection; adding the fractional acceptance number sampling scheme for selection: eliminating the sampling characteristic curve diagram and table of the design value sampling scheme, and adding the sampling characteristic curve diagram and table of the single sampling scheme;
adding the sampling characteristic curve of the design value of the sampling plan that does not consider the impact of the suspended inspection (see Table 12). Appendix A of this part is an informative appendix

Attribute sampling inspection procedure
GB/T2828.1—2003/ISO2859-1:1999 Part 1: Sampling plans for batch inspection indexed by acceptance quality limit (AQL)
1.1: This part of GB/T 2828 specifies a sampling inspection system for attributes. This part uses the term acceptance quality limit (AQL) for indexing.
The purpose of this part is to create economic and psychological pressure on suppliers through batch rejection to keep their processes at least as good as the specified acceptance quality limit on average, while at the same time providing an upper limit on the risk of users occasionally accepting poor-quality batches. The sampling plans specified in this part of GB/T 2828 may be used for (but not limited to) the inspection of the following: final product:
components and raw materials:
operations;
work in process;
stock;
maintenance operations:
—data or records;
—management procedures.
1.2 These sampling plans are mainly used for continuous series of batches. The length of the series of consecutive batches is sufficient to allow the use of transfer rules (see 9.3). These rules are:
a) to provide a protection to the user by transferring to a more stringent inspection or suspending sampling inspection as soon as a deterioration in quality is detected; b) to provide an incentive to reduce inspection costs by transferring to a more relaxed inspection as determined by the responsible authority once a consistent good quality has been achieved.
The sampling plans of this part may also be used for the inspection of isolated batches, but in this case, the user is strongly recommended to consult the sampling characteristic curves of the sampling plan (see 12.1) in order to find a sampling plan that gives the desired protection. The user may also refer to the sampling plans retrieved by limit quality (LQ) given in GB/T 15239-1994. 2 Normative references

The definitions of some terms in this part are the latest or newly defined in this part. 3. 1.1
Inspection inspection
The activity of inspecting, testing or measuring one or more characteristics of a product or service to determine whether the various properties of the product or service are qualified and to specify the requirements for comparison.
Original inspection
The first inspection of a batch in accordance with this standard: Note: It is necessary to distinguish between initial inspection and inspection of previously unaccepted or resubmitted batches. 3.1.3
Inspection by attributes Inspection by attributes Inspection based on one or a group of specified requirements, or only classifying unit products as qualified or unqualified - or only counting the number of unqualified units in the unit product.
Note: Counting inspection includes both inspection of whether the product is qualified and counting the number of unqualified units. 3.1. 4

NOTE 2: They should usually be classified according to the severity of the nonconformity, for example: Class A is the type of nonconformity that is of most concern. In the acceptance sample, this type of nonconformity will be assigned a very small AQI value
- Class B is considered a type of nonconformity that is slightly less serious than Class A. If there is a third type (Class C) nonconformity, a Class B conformity can be assigned an AQI value that is greater than that of a Class A conformity but less than that of a Class C nonconformity. Other nonconformities are referred to in this way. Note 3: The characteristics and nonconformity classifications will affect the overall probability of acceptance of the product. Note 4: The items of nonconformity classification, the classification to which they belong and the acceptance quality limits selected for each category are the requirements for the specific situation. 3.1.6
defect
does not meet the requirements of the use period.
Note 1: When evaluating the durability of a product or service according to customary practices, the term "defect" is applicable (in contrast to the standard). Note 2: As the term "defect" has a clear meaning in the legal field, it should not be used as a general term. 3.1.7

Note 2: The sampling plan does not include the rules on how to draw the samples. Note 3: For this part of GB/T 2828, a distinction should be made between sampling plans (see 3.1.17), sampling plans (see 3.1.18) and sampling systems (see 3.1.192):
sampling plan sampling schemc
A combination of a sampling plan and the rules for changing from one sampling plan to another. Note, 9.3.
Sampling system simplifying system
A collection of sampling plans or sampling programs and sampling procedures. Among them, the sampling plan carries the rules for changing the sampling plan, and the sampling procedure includes the inference of selecting an appropriate sampling plan or sampling plan. H: This part of GB/T 2828 is a sampling system based on batch range inspection level and AQL retrieval. In GB/T 15239994 gives another sampling system for the sampling plan. 3.1.20
Normal inspectionnormalnspctior
A method of using the sampling plan (see 3.1.17) when the process average (see 3.1.25) is better than the acceptance quality limit (see 3.1.26). In this case, the sampling plan has acceptance criteria set to ensure that the manufacturer accepts with a high probability. Note: When there is no reason to worry that the process average (see 3.1.25) is different from a certain acceptable level, normal inspection is performed. 3. 1.21
tightened inspection tightened inspection is the use of a sampling plan with more stringent acceptance criteria than the corresponding normal inspection plan. Note: When the results of a predetermined number of consecutive batches indicate that the process average (see 8.1.25) may be inferior to the acceptance quality limit (see 3.1.25), a production inspection is carried out.

Special application of a sampling plan with a lower cost than the normal inspection sampling plan and an acceptance criterion that is not much different from the acceptance criterion of the normal inspection sampling plan.
Note 1: The discrimination ability of a relaxed inspection is less than that of a normal inspection. Note 2: A relaxed inspection may be performed when the inspection results of a predetermined continuity number indicate that the process average (see 3.1.25) is better than the acceptance quality limit (see 3.1.29). 3.1.23
Switching score
In the case of normal inspection, an indicator used to determine whether the current inspection results are sufficient to allow transfer to effective inspection. Note: See 2.3.3
Acceptance scoreacceptance score
For a fractional acceptance number sampling plan, an indicator used to determine the acceptability of a lot. NOTE See 13.2.1.2
Process mean
The average process quality level over a specified period of time or production volume. NOTE In this part of ISO/TS 28, process mean is the quality level of the process during which it is in a state of systematic control (regardless of the number of qualified products or the number of nonconforming units produced).
Acceptance quality limit acceptance quality limit The worst process average quality level permissible when a series of batches are submitted for acceptance sampling. NOTE 2 This term is used only when there are transfer rules and temporary rules as used in Part 10 of (18/28). NOTE 2 Although products with the same quality as the acceptance quality limit may be accepted with a higher probability, the specified acceptance quality limit does not mean that the acceptance quality limit is the desired quality level. The sampling rules and transfer rules and temporary sampling inspection rules in this part of GB/T 2828 are designed to encourage the party to have a process average better than AQL. If the process average is not better than AQL, there will be a risk of transferring to production inspection and making the acceptance criteria more stringent. Once the tightened inspection is carried out, corrective actions must be taken to improve the process, which may lead to temporary sampling inspection. The user's risk quality is the corresponding level of the batch weight level or process quality level of the user's risk. NOTE: The service risk is usually specified as 10% of the limit quality inaiting. qun!ity

4 Representation of nonconformity
4.1 General
The degree of nonconformity is expressed in terms of the number of nonconforming products (see 3.1.8 and a.1.9) or the number of nonconforming products per hundred units (see 3.1.10 and 3.1.3). .1.11) indicates. Tables 7, 8 and 10 are based on the assumption that the occurrence of nonconformities is random and statistically independent. If it is known that a certain nonconformity of a product may be caused by a certain condition, which may also cause some other nonconformities, then only whether the product is a conforming product should be considered, rather than how many nonconformities the product has. 4.2 Classification of nonconformities
Because most acceptance sampling involves more than one quality attribute, and because their importance in terms of quality and (war) economic effects may be different, it is often necessary to divide the types of nonconformities according to the classification defined in 3.1.5. The number of types, the designation of nonconformity classes and the AQL selected for each class are suitable for the quality requirements of the specific occasion. 5 Acceptance quality limit (AQE)
5.1 Usage and Application This part of GB/T 2828 uses the AQL and sample size codes (see 10.2) to retrieve the required sampling plan and sampling plan. When a specified AQ value is assigned to a nonconformity or group of nonconformities, it indicates that the sampling plan will accept the vast majority of submitted lots if the quality level (percentage of nonconforming items or number of nonconforming items per 100 units of product) is not greater than the specified AQI. The provided lot sampling plan is arranged so that for a given AQI, the probability of acceptance at AQE. depends on the sample size. Generally speaking, the probability of acceptance for a large sample is higher than that for a small sample. The AQL is a parameter of the sampling plan and should not be confused with the process average that describes the level of manufacturing operation. Under this sampling system, in order to avoid excessive rejection of lots, the process average is required to be better than the AQL. NOTE: Specifying an AQI does not imply that the supplier has the right to deliberately supply any nonconforming product. 5.2 AQL The AQL used shall be specified in the contract or by the responsible department (or by the responsible department in accordance with the prescribed practice), as defined in 3.1.: Different AQLs may be assigned to groups of nonconformities or to individual nonconformities. The division of nonconformities into groups shall be adapted to the quality requirements of the particular occasion. In addition to assigning AQLs to individual nonconformities, AQLs may be assigned to groups of nonconformities. When the quality level is expressed as a percentage of nonconforming products (3.1.8 and 3.1.9), the AQL value shall not exceed 10 million nonconforming products. When expressed as the number of nonconforming products per hundred units (see 3.1.10 and 3.1.[1]), the AQL value shall not exceed 10 million nonconforming products. When the quality level is not specified, AQI values up to 1100 nonconforming units per 100 units may be used. 5.3 Preferred AQI
The AQL values given in the tables are referred to as the preferred AQL range. For any product, if the specified AQ. is not one of these values, the tables do not apply.
B Submission of Sampling Products
6. Composition of Lots
Products shall be assembled into identifiable lots, sub-lots or other deliverable forms (see 6.2). As far as practicable: Each lot shall consist of products of the same type, 6
foodmate.net交流资料CB/T 2828.1—2003/IS0 2859-1:1999 Grouping of products of the same grade, type, size and composition under the same basic conditions of time and space. 6.2 Provision of lots
The composition of the lot, the lot size and the manner in which each lot is presented and identified by the supplier shall be specified or approved by the responsible authority. The supplier shall provide, where necessary, adequate and suitable storage space for each lot, equipment for proper identification and removal, and personnel to transport the product.
7 Acceptance and rejection
7.1 Acceptability of lots
The acceptance of a lot shall be determined by the use of one or more sampling plans. When the results of a sampling procedure are involved, the term "not accepted" shall be used instead of "rejected". The term "rejected" shall be reserved for the appropriate action that the user may take. The term "rejected" shall be interpreted as "rejection number". 7.2 Treatment of unacceptable batches
The responsible department shall decide how to treat unacceptable batches, such batches may be scrapped, sorted (replacing or not replacing nonconforming products), returned, further specified for more specific applicable criteria, or stored as a supplementary material. 7.3 Nonconforming products
If a batch is accepted, it is authorized to reject any nonconforming products found during inspection, regardless of whether the products form part of the sample. Nonconforming products found may be reworked and replaced with conforming products. With the approval of the responsible department, they may be submitted for inspection again in the manner specified by the responsible department:
4 Classification of nonconforming or nonconforming products
For special provisions for two or more categories of nonconforming or nonconforming products, a set of sampling plans is required. Usually, these sampling plans have a common sample size: however, because each category has a different AQI, they have different acceptance numbers as shown in Table 2, Table 3 and Table 4. 7.5 Special Provisions for Fatal Nonconformities Certain types of nonconformities may be considered critical. This clause provides for special provisions for such designated nonconformities. With the approval of the responsible department, the supplier has the right to inspect each product submitted for these designated nonconformities and to reject the batch if a single nonconformity of this type is found. The responsible department also has the right to reject any batch submitted by the supplier if a batch of samples taken from the batch contains one or more nonconformities of this type. 7.6 Resubmission of Batches
If a batch is found to be unacceptable, the inspection shall be communicated to all parties. Such batches shall not be submitted again until all products have been re-inspected and re-tested and both parties are satisfied that the supplier has eliminated all nonconforming products and replaced them with conforming products, or has corrected all nonconformities. The responsible department shall determine whether re-inspection shall use normal inspection or tightened inspection and whether re-inspection shall include all types of nonconformities or only the individual types that originally caused the nonconformity.
8 Sample selection
8.1 Sample selection
The products to be sampled shall be selected by simple random sampling (see 5.7 of G3/T3358.1:1993). However, when sub-batches or strata (identified by some reasonable criteria) are used, stratified sampling shall be used. In this way, the sample size of each batch or stratum is proportional to the size of the sub-batch stratum.
8.2 Time of sampling
The samples may be taken after the batch is produced or during the batch production. In both cases, the samples shall be selected according to 8.1. .3 Second or multiple sampling
When the first or multiple sampling is used, each subsequent sample shall be selected from the remaining part of the same batch box.foodmate.net exchange information7
GB/ 2828.1—2003/ISO 2859-1:19999 Normal, Tightened and Relaxed Inspection
9.1 Start of Inspection
Unless otherwise directed by the responsible authority, the start of inspection shall be inspection with stop band inspection. 9.2 Continuation of Inspection
Unless the transfer procedure (see 9.3) requires a change in the severity of the inspection, the normal, tightened or relaxed inspection shall continue for successive batches. The transfer procedure shall be used separately for each type of nonconforming or unacceptable product. 9.3 Transfer Rules and Procedures (see Figure 1)
The current transfer shall be divided into
at least 30 minutes

When normal inspection is in use, if all of the following conditions are met, transfer to relaxed inspection should be made: 8) The current transfer score (see 9.3.3, 2) is at least 30 points: [) Production is stable:
The responsible department considers relaxed inspection desirable,
9.3.3.2 Transfer score
Unless otherwise specified by the responsible department, the transfer score should be calculated at the beginning of normal inspection. At the beginning of the positive belt inspection, the transfer score is set to 0. The transfer score should be updated after each subsequent batch is inspected. #) Single sampling plan
1) When the acceptance number is equal to or greater than 2, if the batch is accepted after AQI, level 1, then add 3 points to the transfer score; otherwise, reset the transfer score to 0
When the acceptance number is or ", if the batch is accepted, add 2 points to the transfer score; otherwise, reset the transfer score to 0.

Exchange informationThe probability of acceptance at a given point depends on the sample size. Generally speaking, the probability of acceptance for a large sample is higher than that for a small sample.
AQL is a parameter of the sampling plan and should not be confused with the process average that describes the level of manufacturing operation. Under this sampling system, in order to avoid excessive batch rejection, the process average is required to be better than the AQL. NOTE: The assignment of an AQL does not imply that the supplier has the right to intentionally supply any nonconforming product. 5.2 AQL Specification
The AQL used is specified in the contract or by the responsible department (or by the responsible department in accordance with the prescribed practice), as defined in 3.1.: Different AQLs can be assigned to groups of nonconforming products or individual nonconforming products. The division of nonconforming groups should be adapted to the quality requirements of the specific occasion. In addition to assigning AQLs to individual nonconformities, AQLs may be assigned to groups of nonconformities. When the quality level is expressed as a percentage of nonconforming items (3.1.8 and 3.1.9), the AQL value shall not exceed 10 million nonconforming items. When the quality level is expressed as the number of nonconforming items per 100 units (see 3.1.10 and 3.1.[1]), AQL values up to 1100 nonconforming items per 100 units may be used. 5.3 Preferred AQLs The AQL values given in the table are referred to as the preferred AQL series. If an AQL other than one of these values is assigned to any product, the table does not apply. B. Submission of Sampling Product 6. Composition of Lots Products shall be assembled into identifiable lots, sublots or other deliverable forms (see 6.2). As far as practicable: Each batch shall consist of products of the same type, grade, type, size and composition, prepared under the same basic conditions of time and space. 6.2 Provision of batches The composition of the batch, the batch size and the manner in which each batch is presented and identified by the supplier shall be specified or approved by the responsible authority. If necessary, the supplier shall provide adequate and suitable storage space for each batch, equipment for proper identification and sampling, and personnel for transporting the product.
7 Acceptance and non-acceptance
7.1 Acceptability of batches The acceptance of batches shall be determined by the use of one or more sampling plans. When referring to the results of the sampling process, the term "reject" is used instead of "reject". The term "reject" shall be used to indicate the appropriate action that the user may take. The term "reject" is used to indicate the appropriate action that the user may take. 7.2 Treatment of unacceptable lots The responsible department shall decide how to deal with unacceptable lots. Such lots may be scrapped, sorted (replacement or nonconforming items), returned for further specification against more specific applicable criteria, or kept as a supplementary information. 7.3 Nonconforming products If a lot is accepted, it is authorized to reject any nonconforming products found during inspection, regardless of whether the product forms part of the sample. Nonconforming products found may be reworked and replaced with conforming products. With the approval of the responsible department, the product may be submitted for inspection again in the manner specified by the responsible department:
. 4 Classification of nonconforming or unqualified products
For special provisions for two or more types of nonconforming or unqualified products, a set of sampling plans is required. Usually, this sampling plan has a common sample size: However, because each type has a different AQI, they have different acceptance numbers as shown in Table 2, Table 3 and Table 4. 7.5 Special reservations for fatal nonconforming types Certain types of nonconformities may be considered important. This clause specifically stipulates special provisions for such designated nonconformities. With the consent of the responsible department, each product submitted for these designated nonconformities has the right to be inspected carefully, and the right to refuse to accept the batch as long as a nonconformity of this type is found. At the same time, the responsible department shall have the right to specify the nonconforming category and shall not accept any batch submitted by the supplier if it is found that one or more nonconforming items of this type are included in the samples taken from a batch. 7.6 Resubmission of batches
If a batch is found to be unacceptable, it shall be communicated to all parties. Such batches shall not be submitted again until all products have been retested and retested and both parties are satisfied that the supplier has eliminated all nonconforming products and replaced them with qualified products, or has corrected all nonconformities. The responsible department shall determine whether normal inspection or tightened inspection shall be used for retesting, and whether the retesting shall include all nonconformities of the same category or only the individual types that were originally nonconforming.
8 Sampling of samples
8.1 Selection of samples
The products to be used as samples shall be selected according to simple random sampling (see 5.7 of G3/T3358.1:1993). However, when there are sub-batches or strata (identified by some reasonable criteria), stratified sampling is used. In this way, the sample size of each batch or stratum is proportional to the size of the sub-batch stratum.
8.2 Time of sampling
The sample can be taken after the batch is produced or during the batch production. In both cases, the sample should be selected according to 8.1. .3 Second or multiple sampling
When the first or multiple sampling is used, each subsequent sample should be selected from the remaining part of the same batch box. foodmate.net exchange information 7
