7 Inspection rules
7.1 Factory inspection
Items for the serial number 1.2, 10 in Table 2.
7.2 Type test
Project for all the items specified in Table 2.
One of the following circumstances, the type test should be carried out:
a) new products or old products transferred to the production of prototype testing;
b) after mass production, such as materials, processes have changed significantly, which may affect product quality and performance;
c) formal production, regularly or after accumulating a certain amount of production, should be periodic (half a year) for a test;
d) the product is discontinued for more than 6 months, when resuming production;
