1 The accumulators specified in the Guidelines are vessels which, utilizing the compressibility of gas, use the gas pressure inside the bladder to apply pressure on the liquid outside the bladder.
2 The Guidelines are applicable to the accumulators using petroleum base hydraulic oil or emulsion as the working medium and having the following general parameters:
Design pressure: p≤63MPa
Design temperature: -40°C~+93°C
Nominal capacity: 0.4L~250L
3 For the structural forms, manufacturing material and working medium of accumulators not mentioned in the Guidelines, reference may be referred to the Guidelines as appropriate.
