Compared with 81-·17, the technical content of the standard has changed significantly: According to 1.1, the standard text is revised, and the method and sample plan table of [8422-155] are used. The parameters of the original plan are cancelled, and the number of vertical numbers is not included. The judgment number of the cabinet is valid and consistent with the original standard. Once the new parameters are used, the yellow column will be re-judged and the decision will be made. This revision has made some necessary changes to some terms and procedures. Appendix A and Appendix B of the standard and Appendix C are normative appendices. Standard 10 is proposed by the National Statistical Standard Application Technical Committee and is the main body of the standard. The main authors are: College of Automotive Engineering, China Standard Research Center, Chinese Academy of Mathematics and Systems Science, Institute of Standardization of Yunlin Industry Co., Ltd. The main authors are: Zhang Sandu, Dian Shimin, Ke Wen, Ma Yixiao, Wei Huiyong, Chang Zhicheng, etc. The standard was first released in 2011. This standard specifies the counting sequence sampling inspection procedures and tables for individual welding operations. The categories in the standard are based on the risk points and the risk points are used as the criteria for TB/T. R051—2002
is a supplement to G/T2328(S02859-1) in that the sampling plan needs to be systematically standardized. Appendix A specifies the sampling plan and sequence of the samples to be subjected to the quality water (A) index: The purpose of this standard is to provide an assessment procedure for the results of the inspection station - using this procedure, the inspection station can carefully reject the inferior products and avoid the economic and internal pressure on the tertiary industry, and provide the production with a high quality report to the society. When selling, the company shall consider the following restrictions: the acceptance of non-quality machinery in the province, the use of the method of scanning and registering the protection of production, and the use of the following ring wet period sample, can be used for the following different particle inspection sites, for example: the total product and raw materials: the production process; the inventory of the company; the maintenance of bamboo; the validity data or.. record; the order of careful expectation. The sampling plan of this standard can be used to determine the degree of non-conforming quantity (or non-conforming product score) or the unit product that does not meet the specifications or the hundred-order production efficiency request. The above card is a random distribution of qualified products for independent production flow design. There may be real reasons to suspect that the incompleteness of a product is due to other factors that may cause incompleteness. If so, it is better to consider whether the product is not qualified enough and ignore more inappropriate situations. The solution in Appendix A is applicable to the same production line. The solution in this standard is also applicable to the current situation.

GB/T8051—2002
In the counting sequence, the unit products are accepted and the decision is made according to the plan. The cumulative number of unqualified products (or the number of non-conforming products) is calculated. After the inspection of each single product, the system and the acceptance batch can be accepted without any information assessment at the inspection stage. If the cumulative science shows that the acceptance is not satisfactory, then the quality level of the batch is small (the risk of using force is insufficient). , then the acceptance is verified and the inspection is signed.
If the risk of the batch is small enough to reject the batch, the inspection will be continued.
If the department indicates that it cannot make a decision, the unit of product can be inspected until the acceptance or rejection decision can be made.
5 Selection of sampling plan
E.1 Selection of single, double and multiple sampling plans E-1.1 Advantages and disadvantages of sequential sampling plans
For a given level of quality, the average sampling rate is the average number of units to be inspected per batch when starting or accepting the batch. As with the single and multiple sampling plans, the use of single sampling plans can reduce the need for single sampling plans to only one unit per cabinet or county. The above, the use of sequential state scheme, more convenient than the single, multiple sampling scheme cost less. For the ten-quality, the maximum number of samples of the secondary sampling scheme can reach or exceed the sample size of the oil production wood tray. The appendix gives the method for determining the approximate value of the average sample size: see the appendix. For a specific batch of "Rong", when using the ratio, the number of samples for actual inspection may exceed the upper limit of the number of samples specified in the secondary, single scheme! The actual upper limit of the number of samples to be inspected is not limited by the sampling speed. The slow inspection sample size may exceed the translation cost by increasing the number of times. In batches: For this standard full-quality bottle sample plan, the cut-off rule is introduced to limit the number of samples that can be sampled. When the plan uses the word push sample plan, the sample quantity cannot be adjusted in advance, so the edge and actual flow inspection of the sample can be carried out without difficulty. One disadvantage is that compared with a market promotion plan, when the hot sequence Shenzhen report method is used, the number of historical averages is judged by the implementer. When the inspection fee is easy to be held responsible: the general plan has a small sample and a larger sample. The disadvantages of the actual performance are trade-offs. 5.1.2 Note: It is against the rules to re-sample the product twice or more. The sampling plan should be studied before the product is started. If the sampling standard is changed or changed intentionally during the sampling, it may lead to a gradual change in the inspection quality. Therefore, this standard does not allow switching between inspection plans. 5.1.3 The sample size should be sufficient. The sampling plan should be increased compared to the old one. In a commercial sense, it is economical - but when testing a specific batch, it may be exposed due to the exposure of the product. The effectiveness of the protection method is very important. When the quality level of the batch is close, it is impossible to stop accepting or change the related judgment. The decision will be made, and the delay in the implementation of the company will be uncertain. This situation may occur when the quality level of the batch is close. Before you can choose the value of the cumulative sample size, you should set a large limit for the machine. When the cumulative sample size is discussed, the pre-inspection should be stopped: the acceptance of the batch should be strictly followed by the rules set by the sampling code before the start of the sampling, and the production standard risk is almost not affected by this change. In [4.? The numerical rules are given. 5.2 Requirements on batches
This standard is based on the statistical theory of the Lato test. This is generally determined: Now, take a sample, each trained G/T 8051-2002
and the details of the war will be released: if the sample is too severe, the batch is V, "point by point, the use of no back sampling for comfort has an out of the situation, these theories are still effective even when the cumulative cost is greater than N. These theories are close to the system. M, science: the law of safety book color

Appendix 4 shows the quality level of the product! Q and detailed code of this volume are used to select the sampling rate of the sample. The sample selection method of the sample plan corresponds to the G2528 (2S-1 oil sample plan of the sampling method of the corresponding state line number 4.3.2 of the non-direct certificate plan that meets the requirements of the two points || tt || The method described in the previous 5-3.2 and 5.5.1 can be used to check the performance of the two lines. Points are used as the index of the general trend table. The corresponding point is the risk point of the producer according to the probability of collection, and the other point is used as the risk point. If there is no special provision, the first two points are selected for the design of the fake auction plan: Generally, the production risk point is 15, and the risk point is 410 (see Figure 1). If the production quality plan is required to have similar characteristics to the previous one, the risk points of the producer and the exporter can be obtained from the corresponding chart of the oil price plan. If such a force accumulation does not exist, it can only guarantee the safety of the Sichuan support plan and the risk points of the direct quality rent. 5.4 Preliminary exploration before inspection 5. 4. 1 Get your sensitivity, within and 8 for a price more than some fast reception and production by each teaching, that is, 8 times the value of this reference teaching corresponds to the production side risk "5.

During the detailed inspection of the acceptance sequence, the unit products are accepted according to the plan and the decision is made according to the accumulated number of unqualified products (or the number of non-compliant products). After the inspection of each unit product: if there is no information in the inspection stage, the batch can be accepted. If the accumulated information shows that the quality level of the batch is not satisfactory (the risk is small enough), then the acceptance certificate will be signed and the inspection will be stopped.
If the department shows that the decision cannot be made, then continue to inspect the unit product: until the information can make a decision on the acceptance or rejection.
5 Selection of sampling plan
E.1 Warehouse, primary or secondary E-1.1 Advantages and Disadvantages of Sequential Sampling Schemes
For a given property level, the average sampling rate is the average number of items to be inspected per batch when the sampling plan is started or collected. As with the single and multiple sampling plans, the use of sequential sampling plans can reduce the cost of sampling only half of the average items required for the single or multiple sampling plans. However, the cost of using sequential plans is lower than that of single and multiple sampling plans. For a given property level, the maximum sample size of the secondary sampling plan can be as large as the average sample size of the fuel oil pallet. The appendix gives a method for determining the approximate average sample size: see Appendix. For a specific batch, when the comparison is used, the actual number of samples may exceed the sample size of the corresponding plan: the secondary and single sampling plan is selected! The upper limit of the actual number of tests is that there is no such limit in the sampling method. The slow test sample quantity may exceed the batch limit due to the repeated addition of samples. For the full-scale sample scheme, the cut-off rule is introduced to limit the number of samples that can be tested. When the sample is pushed, the sample quantity is not adjusted in advance. Therefore, the upper and lower sample quantities and the actual test performance can be carried out without difficulty. One disadvantage is that when the sample is pushed, the number of samples is judged by the implementer. When the test is easy to be responsible, the plan has the disadvantages of smaller samples and greater performance. The choice of re-sampling is against the standard. 5.1.2 Note: When selecting a second or multiple sampling, the sampling plan should be considered in the work of the sampling plan. And before the product is studied, if the sampling standards are changed or too strong, it may lead to a gradual change in the inspection policy. Therefore, this standard does not allow the conversion between inspection schemes: 5.1.3 The sample size must be sufficient. In the commercial sense, for the economic purpose, but for a certain batch of inspections, the sampling method must be increased compared with the old method. The product may be exposed due to the existence of a direct protection method that is not effective. It is too late to make a judgment, stop acceptance or change the relevant situation, and make a decision. The next step into the city will be delayed. This situation may occur when the quality level of the batch is close to that of the original batch. In this case, a large limit should be set before selecting the value of the original batch. When the cumulative sample size is discussed, the pre-inspection should be stopped: the acceptance and reporting of the batch should be carried out according to the rules set by the sampling code before the start of the sampling, and the production standard risk is almost not affected by this change.

Design the false sampling plan If there is no special provision, please select these two points: Generally, the production side risk is 15, and the risk is 410 (see Figure 1). If the oil quality plan is required to have similar characteristics to the previous one, the risk points of the production side and the exporter can be obtained from the corresponding chart. If such a risk does not exist, it can only guarantee the safety of the plan and the risk point with the lowest quality. 5.4 Preliminary exploration before inspection 5. 4. 1 Get your sensitivity, within and 8

In the counting sequence, the unit products are accepted according to the plan and the cumulative number of unqualified products (or non-compliant numbers) is used to calculate the number of non-compliant products. After the product inspection, if there is no information in the inspection stage, the batch can be accepted according to the assessment. If the inspection stage shows that the quality level of the batch is not satisfactory (the risk of production capacity is small enough), then the acceptance certificate will be rejected and the inspection will be stopped. If the department indicates that the quality level of the batch is not satisfactory (the risk of production capacity is small enough), then the acceptance certificate will be rejected. If the department indicates that the quality level of the batch is not satisfactory (the risk of production capacity is small enough), then the acceptance certificate will be stopped and the inspection will be stopped. 5. Selection of sampling plan
E.1 Selection of single, double and multiple sampling plans E-1.1 Advantages and disadvantages of sequential sampling plans
For a given level of oxygen in a property, the average sampling rate is the average number of items to be inspected per batch when starting or accepting the property plan. As with single and multiple sampling plans, the use of sequential sampling plans can In order to obtain the characteristics of the industry or the secondary sampling plan, there is a need for a small half-average single unit cost. In the above, the sequential plan is used quickly, which is more convenient than the single sampling plan. The cost of multiple sampling plans is smaller. For the ten-year quality, the maximum sample size of the secondary sampling plan can be transported to the section of the oil production wood tray or the section of the test length that exceeds the test length. The appendix gives the method for determining the approximate value of the sub-sampled wood: see the appendix. For a specific batch of "Rong", when using the comparison, the case will become the world pole force factor, and the actual number of samples may be changed by a relatively strict control. The sample of the case: the text is about the second, single scheme selection! The upper limit of the actual number of tests, the sampling method is appropriate, there is no such limit, the slow test sample quantity may be contributed to the number of batches beyond the limit: for the full character sample scheme, the cut-off rule is introduced to limit the number of samples that can be planned. When the case is pushed by the character sample, the sample quantity is not adjusted in advance, so the actual test can be carried out without difficulty, and a proof is not The disadvantages are: compared with a market promotion plan, when the hot sequence reporting method is implemented, the historical average number is judged by the implementer, and the inspection fee is easy to be held responsible: the general plan has a small sample size and a relatively strong correction ability. The choice of using the sequence re-sampling plan is against the rules. 5.1.2 Note: The selection of the second or multiple times should be considered. The sequence sampling plan should be studied before the product is started. If the sampling standard is changed or the sampling is too strong, It may lead to gradual changes in the policy of inspection. Therefore, this standard does not allow conversion between inspection schemes. The following types of promotion schemes are recommended: 5.1.3 Depending on the sample size, it is necessary to make an additional sampling method than the old one. In the commercial sense, for the economic purpose, but for a specific batch of inspections, the product may be exposed due to the existence of a direct protection method that is very effective. When the protection is too effective, it is impossible to stop accepting or change the relevant judgment at a later time. The next step into the mountain society is uncertain. The delay in the development of the city. This situation may occur when the quality level of the batch is close to that of the original batch. In this case, a large limit should be set before selecting the value of the original batch. When the cumulative sample size is discussed, the pre-inspection should be stopped: the acceptance and reporting of the batch should be carried out according to the rules set by the sampling code before the start of the sampling, and the production standard risk is almost not affected by this change. In [4.? The numerical rules are given. 5.2 Requirements on batch size

CR2-GX.P1 Advantages and Disadvantages of Sequential Sampling Schemes
For a given level of oxygen in a property, the average number of items to be inspected per batch is the highest when the sampling rate is the highest. As with single- and multiple-sampling schemes, using sequential sampling schemes can reduce the average number of items required to be inspected per batch or multiple-sampling scheme. However, using sequential sampling schemes reduces the cost of sampling compared to single- and multiple-sampling schemes. For the quality of the ten batches, the maximum number of samples of the secondary sampling scheme can reach the average sample size of the oil-producing wood. The appendix gives the method for determining the approximate value of the average sample size: see the appendix. For the specific batches of "Rong", when using the ratio, the number of samples for the actual inspection may exceed the upper limit of the number of samples specified in the secondary sampling scheme: the number of samples selected for the secondary sampling scheme is strictly controlled! There is no such limit on the speed of the sampling method. The slow inspection sample size may exceed the upper limit of the actual inspection number. In batches: For this standard full-quality bottle sample plan, the cut-off rule is introduced to limit the number of samples that can be sampled. When the plan uses the word push sample plan, the sample quantity cannot be adjusted in advance, so the edge and actual flow inspection of the sample can be carried out without difficulty. One disadvantage is that compared with a market promotion plan, when the hot sequence Shenzhen report method is used, the number of historical averages is judged by the implementer. When the inspection fee is easy to be held responsible: the general plan has a small sample and a larger sample. The disadvantages of the actual performance are trade-offs. 5.1.2 Note: It is against the rules to re-sample the product twice or more. The sampling plan should be studied before the product is started. If the sampling standard is changed or changed intentionally during the sampling, it may lead to a gradual change in the inspection quality. Therefore, this standard does not allow switching between inspection plans. 5.1.3 The sample size should be sufficient. The sampling plan should be increased compared to the old one. In a commercial sense, it is economical - but when testing a specific batch, it may be exposed due to the exposure of the product. The effectiveness of the protection method is very important. When the quality level of the batch is close, it is impossible to stop accepting or change the related judgment. The decision will be made, and the delay in the implementation of the company will be uncertain. This situation may occur when the quality level of the batch is close. Before you can choose the value of the cumulative sample size, you should set a large limit for the machine. When the cumulative sample size is discussed, the pre-inspection should be stopped: the acceptance of the batch should be strictly followed by the rules set by the sampling code before the start of the sampling, and the production standard risk is almost not affected by this change. In [4.? The numerical rules are given. 5.2 Requirements on batches
This standard is based on the statistical theory of the Lato test. This is generally determined: Now, take a sample, each trained G/T 8051-2002
and the details of the war will be released: if the sample is too severe, the batch is V, "point by point, the use of no back sampling for comfort has an out of the situation, these theories are still effective even when the cumulative cost is greater than N.

If there is no special provision, the first two points are selected for the design of the fake auction plan: Generally, the production risk point is 15, and the risk point is 410 (see Figure 1). If the production quality plan is required to have similar characteristics to the previous one, the risk points of the producer and the exporter can be obtained from the corresponding chart of the oil price plan. If such a force accumulation does not exist, it can only guarantee the safety of the Sichuan support plan and the risk points of the direct quality rent. 5.4 Preliminary exploration before inspection 5. 4. 1 Get your sensitivity, within and 8 for a price more than some fast reception and production by each teaching, that is, 8 times the value of this reference teaching corresponds to the production side risk "5.

CR2-GX.P1 Advantages and Disadvantages of Sequential Sampling Schemes
For a given level of oxygen in a property, the average number of items to be inspected per batch is the highest when the sampling rate is the highest. As with single- and multiple-sampling schemes, using sequential sampling schemes can reduce the average number of items required to be inspected per batch or multiple-sampling scheme. However, using sequential sampling schemes reduces the cost of sampling compared to single- and multiple-sampling schemes. For the quality of the ten batches, the maximum number of samples of the secondary sampling scheme can reach the average sample size of the oiThe user quantity should be used separately, and R=A+1 replaces A and K.
