scope:

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 fluid power accumulators;

− common requirements and an industry-wide philosophy in judging one type of pressure capability for fluid power accumulators;

− uniform methods of product comparison.

This standard covers the pressure containing envelope of the following accumulator types:

− piston;

− bladder;

− diaphragm;

− direct acting;

− mechanical;

− mechanical spring;

− mechanical weighted;

− metal bellows;

− gas bottles, are also included, only when they are used as an extension of the gas volume of one of the above mentioned accumulators.

This standard limits conditions as follows:

Follow 1.2 from NFPA/T2.6.1 R2.

This standard encourages manufacturers to use this common method to enhance the credibility of their pressure ratings.
