Scope

This document specifies the dimensions, configurations, and markings of non-interchangeable NIST fittings intended for use in medical gas systems with a maximum working pressure not exceeding 1,400 kPa and vacuum systems with an absolute pressure not exceeding 60 kPa.
This document applies to NIST fittings used with medical gases [oxygen, nitrous oxide (laughing gas), medical air, helium, carbon dioxide, xenon, specific mixtures of the aforementioned gases, 93% oxygen, air for driving surgical instruments, nitrogen for driving surgical instruments, and vacuum].
Note 1: GB/T 46042 specifies low-pressure hose assemblies for medical gases and vacuum.
This document does not specify the information provided by manufacturers, as the information on the use of NIST fittings permanently installed on various medical devices is provided by the manufacturers of these devices.
Note 2: The impact on the environment is mentioned in the standards for medical devices compatible with NIST fittings.
