NFPA/T3.6.31 R2-2000 (R2019)
Telescopic cylinders and cylinders of non-bolted end construction - Pressure rating supplement to NFPA/T2.6.1 R2-2000, Fluid power components - Method for verifying the fatigue and establishing the burst pressure ratings of the metal pressure containing envelope of a telescopic and non-bolted end fluid power cylinder
This standard provides: test and statistical methods for generating fatigue distribution data; test and statistical methods for conducting a verification of the pressure ratings on telescopic and nonbolted end fluid power cylinders; common requirements and an industry-wide philosophy in judging one type of pressure capability for telescopic and nonbolted end fluid power cylinders; uniform methods of product comparison. Follow NFPA/T2.6.1 R2. This standard encourages manufacturers to use this common method to enhance the credibility of their pressure ratings.
