Scope

This standard specifies the requirements, inspection rules and test methods, marking, certificates, packaging and transportation of main steel forgings (hereinafter referred to as forgings) for positive displacement compressors. This standard applies to free forgings (including membrane forgings) and die forgings for positive displacement compressors such as high-quality carbon steel, alloy structural steel and stainless steel produced on forging equipment such as forging hammers and hydraulic presses. This standard does not apply to special forgings such as pressure vessels.
