Division 2.7.7.3 Reduced number of duty cycles

The vehicle manufacturer may specify a reduced number of duty cycles for each hydrogen component, calculated by applying the following formula:

Number of duty cycles based on 20 years service life: 50 000

Design service life: x years; x ≥ 1

Reduced number of duty cycles:

10 000 + 2 000*x

The hydrogen components shall be replaced before exceeding their specified service life.
