4 Specified service conditions
4.1 Maximum allowable working pressure
The maximum allowable working pressure shall be specified by the pressure vessel manufacturer,
shall not be less than 15 MPa and shall not exceed 110 MPa.
4.2 Maximum allowable energy content
The maximum allowable energy content of a single pressure vessel shall not exceed
300 000 MPa·l.
4.3 Maximum and minimum allowable temperature
The maximum allowable temperature and the minimum allowable temperature shall be specified
by the pressure vessel manufacturer and noted on the name plate.
The specified value for the maximum allowable temperature shall not be less than 50 °C and shall
not exceed 85 °C.
The specified value for the minimum allowable temperature shall not exceed −25 °C and shall not
be less than −50 °C.
The manufacturer may specify a distinct maximum temperature not to be exceeded during
maintenance (e.g. for painting).
4.4 Pressure cycle life
The pressure cycle life in hydrogen service shall be specified by the pressure vessel manufacturer.
The owner/operator may elect to further restrict to number of cycles allowed.
4.5 Shallow pressure cycle life
A shallow pressure cycle life may optionally be specified by the pressure vessel manufacturer or
user. In this case, the shallow pressure cycle life shall be at least three times the pressure cycle
life.
The shallow cycle life shall be calculated according to one of the methods given in 4.6.3, 8.3.5 or
experimentally determined according to methods described in A.7.
4.6 Effective pressure cycle count and maximum number of pressure cycles
allowed in service
4.6.1 General
One of the following methods shall be used to determine the pressure cycles life of the cylinder.
4.6.2 Pressure cycles calculation method — Method described in Annex B
For all types of vessels, the number of cycles equivalent to full cycles (guaranteed in a given
standard) can be calculated according to the formula given in Annex B.
4.6.3 Pressure cycles calculation method — Goodman diagrams method described in
Annex F
The cycle life may be determined by the use of a Goodman diagram and Miner’s Rule. The
Goodman diagram shall be based on fatigue testing of similar materials and construction as the
vessel to be qualified. An example of this approach is provided in Annex F.
