Gas-loaded accumulators for fluid power applications EN 14359:2017

Publication date:   Jul 12, 2017

Scope

1.1 This European Standard specifies the requirements for materials, design, manufacture, testing inspection, safety equipment configuration and documentation (including instructions for first operation), for commonly-used types of gas-loaded accumulators and pressure vessels used to provide additional gas capacity for fluid power applications (see 1.2).
1.2 This European Standard applies to the following types of components, defined as the pressure-containing envelope of gas-loaded accumulators:
- bladder type;
- diaphragm type;
- piston type;
- transfer type;
- pressure vessels used to provide additional gas capacity.
They consist of one or several parts joined together by a variety of mechanical means and by welding.
1.3 This European Standard applies to gas-loaded accumulators which operate with the following conditions:
- subject to an internal gauge pressure greater than 0,5 bar;
- working temperature not lower than -50 °C and not higher than +200 °C;
- containing all liquids and gases as defined in the Pressure Equipment Directive 2014/68/EU,
see Note.
NOTE When the accumulator contains Group 1 liquids or gases, consideration relating to risks other than those required by Pressure Equipment Directive 2014/68/EU are not covered by this European Standard and must be assessed separately.
