8 Acceptance rules
8.1 Test classification
8.1.1 The test types specified in this Part are divided into routine test (code R),
sampling test (code S) and type test (code T).
8.1.2 Each batch of products shall be subjected to routine test (i.e. test of all
delivered products) and sampling test. Each batch of products shall be
subjected to routine test and sampling test by the quality department of the
supply party, and they shall be qualified before exiting the factory.
8.1.3 Type test is used to test the main performance of bus bars. The test is
only done once for the newly designed bus bars or the bus bars produced with
the new production process, and the test is only redone after the design or
production process has changed. Type test is only carried out on bus bars that
meet all relevant routine and sampling test requirements.
8.1.4 The test items and test types shall comply with the requirements of Table
12.
8.2 Sampling rules
The sampling rules of products shall be determined by agreement upon the
supply and demand parties. If the demand party does not request, it is
implemented according to the provisions of the supply party.
8.3 Qualification judgment
The test results of all test items shall comply with the requirements of Table 12.
If any item of the sampling test fails, the unqualified test items shall be double-
sampled and tested. If they are still unqualified, 100 % inspection shall be
carried out, and qualified products may be delivered.
