- Scope
- This standard specifies the verification method for the rated fatigue pressure and rated static pressure of the pressure chamber of a hydraulic accumulator. This standard applies to gas-liquid accumulator pressure chambers made of metal materials. This standard also applies to hydraulic transmitters made of metal materials used to separate two liquids and gas bottles connected to the gas storage chamber of the accumulator. This standard does not apply to accumulators, hydraulic transmitters and gas cylinders made of non-metallic materials, nor to accumulators of non-gas-liquid type (such as hammer type or spring type). This standard does not apply to verification after material strength has decreased due to chemical reactions or metal corrosion.
