This standard provides:
âˆ’ test and statistical methods for generating fatiguedistribution data;
âˆ’ test and statistical methods for conducting a verification ofthe pressure ratings on fluid power accumulators;
âˆ’ common requirements and an industry-wide philosophy in judgingone type of pressure capability for fluid power accumulators;
âˆ’ uniform methods of product comparison.
This standard covers the pressure containing envelope of thefollowing accumulator types:
âˆ’ direct acting;
âˆ’ mechanical spring;
âˆ’ mechanical weighted;
âˆ’ metal bellows;
âˆ’ gas bottles, are also included, only when they are used as anextension of the gas volume of one of the above mentionedaccumulators.
This standard limits conditions as follows:
Follow 1.2 from NFPA/T2.6.1 R2.
This standard encourages manufacturers to use this common methodto enhance the credibility of their pressure ratings.
