1.1This 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).1.2This 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;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.1.3This 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).NOTE 1Fluid power applications utilize non-dangerous fluids as categorized in ISO 6743-4 in addition to an inert gas (e.g. nitrogen) which is used as the pre-charging medium.NOTE 2There are no design limits to the volume of the accumulator.
