By providing a uniform framework, ASME PTC 9 ensures that tests conducted by different parties on similar equipment produce comparable, accurate, and verifiable results. It applies to compressor units operating under conditions that allow the discharge of compressed gas into the atmosphere or into pipelines where the pressure is uniform and free from pulsations.
