3.1 Initial manufacturing stage
The initial manufacturing stage defined in 8.5.2 of the process rule QC001002 refers to the first process after the processing of parts and subassemblies is completed. A permanent assembly consisting of two or more parts is defined as a subassembly. The initial manufacturing stage and all subsequent processes shall be carried out under the direct supervision of the chief inspector of the approved manufacturer. They may be carried out by subcontractors in accordance with the same original plan.
3.2 Structurally similar components
CB/T 15157—94
As defined in 8.5.3 of the process rule QC001002, connectors with basically the same design, the same contact specifications and alternate contact surface coatings are defined as structurally similar components. They may differ in other performance aspects, such as: number of contacts, external dimensions, installation, termination method, etc., but they shall be produced using the same production process and method. Structurally similar connectors may be included in one or more detailed specifications. Connectors covered by a detail specification are considered to be structurally similar. Other details are governed by the detail specification. For the purpose of quality conformity inspection and sampling, all connectors of similar construction may be placed in one inspection lot. 3.3 Classification of levels
The term "level" is used in the following different meanings, which shall be clearly distinguished. A detail specification may contain more than one combination of performance level and assessment level. All details of these levels and their combinations shall be specified in the detail specification. Performance levels and their assessment levels shall be clearly specified in the detail specification.
3.3.1 Performance level
The performance level depends on four factors: climate category, test schedule, severity of test conditions and requirements. Changing one or more of these factors, such as climate category, scope and (war) severity of test schedule, requirements, will result in different performance levels.
This specification includes a "basic test schedule" and a "comprehensive test schedule". When a "medium test schedule" is specified, these two schedules shall be clearly given, and an explanation shall be given as to how the medium test schedule is specified. These test schedules, together with the severity used and the requirements specified in the detail specification to be met, define the performance level of the component. There is only one performance level for a given type of component. If two components have different performance levels, they shall be considered as two different components and shall have two different types.
In the type, the performance level shall be indicated by a number (1, 2 or 3) and shall be specified by the detail specification. 3.3.2 Assessment level
The assessment level is a combination of the number of samples and the acceptable number of nonconforming items. For a structurally similar connection, there is only one assessment level for each performance level.
When the number of samples is fixed, the assessment level is determined by the number of samples tested and the acceptable number of nonconforming items. Fixed sample numbers are usually used for periodic inspections in qualification approval inspections and quality consistency inspections. When variable sample numbers are used, the assessment level is defined by the "inspection level IL" and the \acceptable quality level AQL\. Variable sample numbers are usually used for batch testing.
In the designation, the assessment level shall be indicated by a letter which shall be specified in the detailed specification. 3.3.3 Inspection level (IL)
The inspection level determines the number of samples associated with the batch (see IEC 410 for details). 3.3.4 Acceptable quality level (AQL)
In [EC.4]0, the upper limit of the acceptable process average (number of nonconforming items per hundred units of product) is defined as AQL. See IEC 410 for details.
3.3.5 Combination of performance level and assessment level In principle, any combination of performance level and assessment level may be used. Practice shows that for connectors of each performance level, only one combination of performance level and assessment level is meaningful. NOTE The relevant code specified in the detailed specification shall be used to indicate each combination of performance level and assessment level by a number and a letter. 3.4 Test grouping
In this specification, the two different test grouping methods used shall be clearly distinguished. 3.4.1 Test groups for qualification approval tests
This section specifies the test list. Test: The list is divided into P, AP, BP, CP, DP and EP test groups. In each test group, the specified minimum number of test samples shall be subjected to each specified test. For qualification approval, the same test list GB/T 15157-94
and test groups and the minimum number of samples to be tested are specified in 3.6 of this specification. The number of non-conforming products that can be accepted shall be specified in the relevant detailed specifications. By specifying these details, fixed rules are established and qualification approval becomes a standardized procedure. The groups specified in this subclause and used for qualification approval tests are called "qualification approval test groups" or "QA test groups". 3.4.2 Test groups for quality consistency testing
Quality consistency testing usually involves fewer tests, because certain tests are only important for qualification approval testing and are not necessarily necessary for testing products currently in production. -Some tests are carried out on a batch-by-batch basis (100 % inspection or by sampling procedure), while for others it is sufficient to carry out only once at shorter or longer intervals. The period of these tests may range from 1 month to 36 months. In view of the convenience for various countries of origin in grouping the tests according to the conduct of the tests, these groups are called "quality-consistency test groups" or "QC test groups".
The following groupings are identified as appropriate:
Batch-by-batch testing, with 100 % inspection or by sampling procedure (QC test groups A and B, see clause 3.7 of this specification). Periodic tests for quality consistency inspection (QC inspection group C, see 3.7. Periodic tests for obtaining or maintaining identification approval (QC inspection group D, see 3.7). 3.4.3 Delayed delivery
Connectors stored for more than 36 months after batch release should be visually inspected before delivery. The detailed specification may specify additional re-inspection items, such as solderability. The re-inspection should use the original assessment level. The quality of the batch that passes the re-inspection should be re-assured for 36 months. 3.4.4 Release of delivery batches before completion of "Group B" tests When the Group B tests have reached the conditions for IEC410 to switch to relaxed inspections, connectors can be delivered before these tests are completed. 3.4.5 Delivery
samples of the tested connectors should not be included in the delivery batch after tests that may affect their quality base. 3.5 Approval of Contractors, Independent Test Laboratories and Distributors Contractors who wish to become IECQ system shall comply with the general requirements specified in Article 10 of QC001002 and the requirements for the initial manufacturing stage specified in Article 3.1 of this specification. Independent test laboratories and test laboratories who wish to become IECQ system shall comply with the requirements specified in Article 10 of QC001002. 3.6 Approval Procedure
For a certain type of connector or a certain range of connectors with similar structures, contractors who wish to obtain approval for approval (Article 3.5) shall apply to the national agency specified in the national regulations (such as: national supervision and inspection agency). The application shall indicate that all procedures, tests, measurements, etc. that can produce approved components have been adopted from the initial manufacturing stage. 3.6.2 Granting of Approval
Approval can be granted in the following cases: The Approval Test as specified in 3.6.7 of the Detailed Specification has been fully completed, and the proof thereof is the Approval Test Report. The Quality-Conformity Inspection as specified in 3.6.7 of the Detailed Specification has been fully completed, and the proof thereof is the Release Batch Certification Record, and three consecutive batches of batch tests and one batch of all relevant periodic tests have been carried out. If the quality consistency inspection test is completely equivalent to the Approval Test, the Quality Conformity Inspection Test may be substituted for the Approval Test. The equivalence of the tests shall be verified by the national supervisory inspection agency. 3.6.3 Scope of Approval
As long as the approval The test connector is representative of a group of connectors of similar construction (see 3.2) and includes the connector with the most and the least contacts for which approval is sought (see 1.1). The approval includes all varieties and specifications in the group. When the scope of the approval is to be extended to include other varieties and specifications with performance exceeding that of the original approval, it is sufficient to test only the additional parts. It is necessary for the manufacturer to consult with the relevant national agencies, such as the national supervision and inspection agency. 3.6.4 Maintenance of the approval approval The maintenance of the approval approval shall be in accordance with the provisions of the procedural rules, that is, the approval is maintained when the following conditions are met: GB/T 15157-94 If the connectors submitted continuously are tested for quality consistency and confirmed by the release batch certification record: If re-evaluation is carried out in the following circumstances: Re-evaluation has been carried out regularly when small quantities or intermittent production of components are carried out, or re-evaluation is carried out when the relevant specifications are revised or major changes are made in accordance with 3.6.6 (in this case, re-evaluation of only the revised parts is sufficient). 3.6.5 The suspension or revocation of the appraisal approval shall be subject to 10.7. 3.6.6 Major changes
Changes in design, materials, technology and (or) manufacturing process are permitted. However, when the changes may affect the appraisal approval, the contractor shall report the changes to the national supervision and inspection agency. 3.6.7 Approval test
The detailed specification shall specify:
