Classification and
assessment of pressu-
rised components
Compressor / compressed air systems and compressor stations are assem-
blies according to the PED. The classification of an assembly according to the
PED is based on the highest category of the individual components.
Outcome of the assess-
ment
Every aspect of the assembly of the pressurised compressor components
mentioned above is excluded from the scope of the Pressure Equipment
Directive (PED).
Justification:
According to Art. 1, 2.f of the PED, assemblies which in their
entirety would fall into Category 1 at the highest are excluded from the scope
of the PED if they are covered by the Machinery Directive.
Installation in com-
pressed air systems
The installation of the assemblies mentioned above in a compressed air sys-
tem does not constitute a new assembly in the sense of the PED, provided
that the integrated components are excluded from the scope of the PED.
