14.12 Periodic checks
A/C service stations (pressure equipment set) must be
checked over regularly as provided by local legislation.
The frequency for the periodic requalification check of:
•
functioning of the container and of the pressure
equipment set and of the related protection/safety
devices/accessories is established by local
legislation and related technical standards;
•
integrity of the container and of the pressure
equipment set is established by local legislation
and related technical standards;
withstanding that:
•
the national laws in force of the country where the
station is commissioned do not provide for a
higher frequency (lower period of time);
•
the bodies in charge, after the results of the
previous checks performed (of commissioning or
period requalification) do not establish different
frequencies.
The checks must be performed by the bodies in charge in
the country where the station is commissioned, in
compliance with the national laws/rules and the related
procedures. Please identify and contact these bodies in
order to establish performance times and modes of
commissioning
and periodic requalification checks
(integrity, functioning, or any other scheduled checks).
Depending on local legislation, the checks may be extended
to
other components to verify the metrolo
characteristics of the integrated instrumentation and the
presence of essential equipment and accessories.
Here below, some possible checks on components subject
to the PED directive are outlined.
VESSEL 20l - Category III (Dir. 2014/68/EU)
•
Make sure no corrosion or leakage is present;
under normal conditions of use, the vessel life is at
