The total number of random inspections shall be calculated according to the annual output of each variety, and shall not be less than 1/5. The random inspection period shall be evenly distributed throughout the year.||tt| |4.5.2 The basic prototype of the new product series has been subjected to type test, and other products should be subjected to random inspection test. 4.5.1 If the product of random inspection test is not qualified, double differential test should be carried out; if there is still non-compliance, it should be subjected to factory test. 4.6 Factory test
4.1 The purchased products should be subjected to factory test. For products with relatively large batches, stable process and stable quality (referring to the return rate less than 2%), at least 1/3 of the units in each batch of production units can be selected for factory test (the return rate is the ratio of the number of units of the same specification that have passed the production and assembly test to the total number of units), and the remaining pumps should be subjected to running test. 4.62 If the pump station product is small, the remaining products should be subjected to factory test. If the return rate is less than 2% during the test, random inspection can be resumed.
