Details
1.1 This standard provides:
- test and statistical methods for generating fatigue-distribution data,
- test and statistical methods for verifying the pressure ratings of quick-action couplings,
- common requirements and an industry-wide philosophy for judging one type of pressure capability for quick-action couplings,
- uniform methods of product comparison.
1.2 This standard limits conditions as follows:
- pressure-induced loadings of constant amplitude,
- product life of at least 100,000 cycles,
- pressure levels and pulse durations as defined in NFPA/T2.6.1 R2, clause 8,
- temperatures that range from the Charpy impact transition temperature to the threshold of creep sensitivity,
- environments which are chemically compatible with the materials in the pressure-containing envelope,
- materials that are aluminum, magnesium, iron, steel, stainless steel, cobalt, titanium, copper-based alloys, nickelbased alloys, or monel. Specifically excluded are creep-sensitive materials such as zinc, plastic, rubber and sealing devices,
- quick-action couplings which are connected and disconnected by a linear or rotational motion, or both,
- quick-action couplings with or without sealing means when uncoupled.
1.3 This standard encourages manufacturers to use this common method to enhance the credibility of their pressure ratings.
