Repairerr/Testing of Air & Hydraulic Componants (Lockheed & Clayton)

Further to my previous post regarding this subject, the reply from a established repairer is in the following paragraph.

The Routemaster vehicle having a hydraulic braking system in which it employs pressure accumulators is not subject to legislative law pressure testing, as the components operate below the required prescribed minimum pressure of 250 bar/litre for testing commercial units.

I would suggest that when an accumulator is bought or subject to a service exchange agreement, the vehicle owner obtain a operational test certificate to be filed with the vehicles log/maintenance records.
