Scope

GB/T 34387-2017 is the English-translated version of 制冷剂用阀门通用性能试验方法.

GB/T 34387-2017 sets out the general performance test methods for refrigerant valves.

Clause 1 states that the standard specifies the test items, test conditions, equipment, samples, test preparation, test procedures and data processing for the general performance testing of refrigerant valves, which it calls the valve throughout, and that it applies to valves for refrigerants R22, R134a, R407C, R410A, R32, R404A, R290 and other refrigerants.

Clause 3 lists the test items in Table 1: tightness test, internal leakage test, moisture content test, impurity content test, mineral oil content test, chloride content test, flow coefficient C value test, high temperature test, low temperature test, temperature change resistance test, humidity resistance test, salt spray test, brass ammonia resistance test, stainless steel stress corrosion resistance test, vibration test, drop impact test, hydraulic strength test, minimum destructive pressure test and fatigue durability test.

The draft stops immediately after that table and the page gives no table of contents, so the clauses that set the test conditions, the equipment, the samples, the procedures and the data processing are not shown.

Clause 2 cites GB/T 2423.1, GB/T 2423.2, GB/T 2423.3, GB/T 2423.5, GB/T 2423.10, GB/T 2423.17, GB/T 2423.22, GB/T 6283, GB/T 10567.2 and GB/T 17213.9.

The standard carries ICS 27.200 and Chinese classification J73, was proposed by the China Machinery Industry Federation and is kept by the National Refrigeration and Air Conditioning Equipment Standardization Technical Committee (SAC/TC238). It was issued on 29 September 2017 and has applied since 1 April 2018.
