13.11 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 to be every 2 years (according to the
Italian law D.M. 1/12/2004, No. 329);
• integrity of the container and of the pressure equipment set is established to be every 10
years (according to the Italian law D.M. 1/12/2004, No. 329);
withstanding that:
• the national laws in force of the country where the 9000 BUS PLUS 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 of the country where 9000 BUS PLUS is
commissioned, in compliance with the national laws/rules and the respective 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
metrological 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.
