ANSI/(NFPA)T3.29.2 R2-2000 (R2005)

Pressure switch - Pressure rating supplement to NFPA/T2.6.1 R1-1991, Fluid power systems and products -Method for verifying the fatigue and establishing the burst pressure ratings of the pressure containing envelope of a metal fluid power pressure switch

This standard provides: test procedures for conducting a verification of the fatigue & establishment of burst pressure ratings on pressure switch envelopes; test & statistical methods for generating fatigue distribution data; common requirements & an industry wide philosophy in judging one type of pressure capability for fluid power pressure switches; uniform methods of product comparison. This standard limits conditions as follows: constant amplitude, pressure induced loading of the elements that constitute or maintain the pressure containing envelope; defined conditions for pressure levels & pulse durations; temperatures from the charpy impact transition temperature to the threshold of creep sensitivity.
