4.1 Inspection responsibility
SJ2062397
Unless otherwise specified in the contract or order, the contractor is responsible for completing all inspections specified in this specification. If necessary, the ordering party or the superior appraisal agency has the right to inspect any inspection items specified in the specification. 4.1.1 Qualification responsibility
All products must meet all requirements of Chapters 3 and 5 of the specification. The inspections specified in this specification should become an integral part of the contractor's entire inspection system. If the contract includes inspection requirements not specified in this specification, the contractor shall also ensure that the products submitted for acceptance meet the contract requirements. Quality consistency sampling does not allow the submission of products that are known to be defective, nor can the ordering party be required to accept defective products.
4.2 Inspection classification
The inspections specified in this specification are divided into:
a. Identification inspection;
b. Quality consistency inspection.
4.3 Inspection conditions
Unless otherwise specified, various tests shall be carried out under the following normal test atmospheric conditions: a. Temperature:
15-35t;
b. Relative humidity:
20%~80%;
c. Air pressure:
4.4 Identification inspection
Air pressure of the test site.
Identification inspection is generally carried out when the design is finalized and the production is finalized. When there are major changes in the main design, process, components and materials of the equipment that affect the important performance of the equipment and make the original identification results no longer valid, identification inspection should also be carried out. Identification inspection should be carried out in a test case approved by the ordering party or the superior certification agency. 4.4.1 Number of samples
The samples for identification inspection should generally not be less than 2 units or as specified by the product specifications. Note: The sample size for reliability, electromagnetic compatibility and other tests shall be in accordance with the regulations or agreed upon by the contractor and the ordering party. 4.4.2 Inspection items

When all inspection items meet the requirements of Chapter 3 and Chapter 5, the identification inspection is considered qualified. If any inspection item does not meet the specified requirements, the inspection shall be suspended. The contractor shall analyze the unqualified item, find out the cause of the defect, take corrective measures, and then continue the inspection from that item or related items. If all inspection items meet the specified requirements after continued inspection, the identification inspection is considered qualified: If there is still an item that does not meet the specified requirements after continued inspection, it is considered unqualified.
