7.5. Product size deviation, coating appearance quality, color difference is not in line with the customer's judgment, the single piece is not qualified, and the qualified product number is allowed to be checked by the supplier.
When the number of qualified products exceeds the standard in Table 6, the batch is judged to be unqualified: we allow the supplier to remotely inspect and accept, and finally deliver the goods.
Even if the machine changes the sample
7.5.4 When the coating performance test is not qualified, the batch is judged to be unqualified: the unit is reported
The number of separated products-limit
7.5.5 When any test piece of the mechanical performance test fails, the batch is returned to the acceptance plan to double the number (including the number of unqualified products in the serial inspection) )'s list of items shall be ranked again for testing. If there are test specimens that do not meet the test requirements, the batch of materials shall not be suitable. E mark, packaging, transportation, storage and inspection shall be on the qualified spraying case. There shall be a label or certificate with the following content: GB5237.5-2004 a) Supplier name and certificate: h) Supplier and quality inspection department,

Falling Sand Test Method
This Appendix specifies the test method for determining the oxygen-carbon film on the aluminum alloy mold by the falling sand test: This Appendix is suitable for the determination of the oxygen-carbon film on the aluminum alloy mold mold. A, 2 Method Summary
GR5237.52004
Use the standard basis and standard guide that meet the requirements of (/T[7) from the specified height. The film on the surface of the test piece is washed, and the wear is stopped by grinding to the exposed base. The unit layer sequence is determined by the standard of the state of the room. A.3 Specimens and requirements
A.3.1 The specimen is a decorative surface of the material. When the sample cannot be directly taken from the profile, the specimen should be made according to the same process method and the same production line. A.3.2 The size is 50mm×2mm
A.4 Reduced test environment
The test is carried out in a room under a relative strength environment of not less than 6%. A.d.11
The test should be noted.
