ASME PTC 9-1970 (R1997) serves as the definitive, though inactive, standard for testing displacement compressors, vacuum pumps, and blowers, providing protocols for capacity and power consumption measurements. The standard, which includes critical updates like the 1972 errata, defines mandatory procedures for performance tests. Purchase the official document on the ASME Store .
