d
–
to be secured to the vehicle by tensioning
straps (clamps).
In the case of aluminium reservoirs, con-
tact surfaces must be designed to inhibit
corrosion or mechanical damage. Tension-
ing straps are to be positioned in such a
way that they do not come in contact with
the base connecting seams. Furthermore,
the reservoir is not to be subjected to any
stress that would jeopardise operating
safety.
Coatings applied to aluminium reservoirs
must not contain lead, and the top coat of
paint must only be applied over a suitable
primer coat. Steel threaded connections
for aluminium reservoirs must have a cor-
rosion-proof coating.
— only to be cleaned using non-alkaline
cleaning agents (aluminium reservoirs).
— to have the interior visible through the
threaded connections.
— to be emptied at regular intervals to pre-
vent the accumulation of condensation
(drainage ring nut at the lowest point of
the reservoir).
e
–
to require no maintenance if item d is
complied with.
f – no welding is to be performed on the
pressure-bearing walls of the reservoir
(casing, base, ring nuts). Furthermore, no
heat treatment or other operation relevant
to safety is to be performed.
g
–
the internal pressure of the reservoir may
exceed the maximum permissible operat-
ing pressure P
s
by no more than 10% for a
brief period.
