1.1 This European Standard specifies the requirements for materials, design, manufacture, testing
inspection, safety systems and documentation (including instructions for first operation), for
commonly-used types of gas-loaded accumulators and gas bottles for fluid power applications (see
1.2).
1.2 This European Standard applies to the following types of components, defined as the pressurecontaining
envelope of gas-loaded accumulators:
? bladder type;
? diaphragm type;
? piston type;
? transfer type;
? gas bottles 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 of not lower than –50 °C and not higher than +200 °C;
? containing Group 2 liquids and gases as defined in the Pressure Equipment Directive 97/23/EC.
It does not apply to:
? accumulators for use with dangerous fluids (see NOTE 1).
