Testing Methods:

 

The ex-factory inspection and all-function test, technical requirement and test method of Solenoid valve should be in compliance with table 1. Among which the ex-factory inspection should be taken as the following: take the whole quantity of valves produced in one shift as a inspection lot, pick-sample and inspect as per normal-level one-time sampling program noted in the sampling table and each lot sample-account program stipulated in GB/T2828-1987, inspection level II. All-function test should be taken as per GB/T2829-1987, judgment level I, twice sampling.
