1 Scope
This European Standard specifies the requirements relating to safety of persons and
property (but not goods in storage) and the local and global environment for:
-
a) stationary and mobile refrigerating systems of all sizes, including heat pumps;
-
b) secondary cooling or heating systems;
-
c) location of these refrigerating systems.
NOTE 1 For secondary heating or cooling systems charged with any refrigerants listed in Annex E the charge limitations of part 1 (Annex C) apply.
For refrigerating systems with a limited mass of refrigerant only some of the parts and clauses are applicable. The exceptions are defined in
the scope and the clauses of each Part of EN 378.
This European Standard is not applicable to refrigerating systems with air or water
as refrigerant. Systems using refrigerants other than those listed in Annex E are not covered by this European Standard as long as a safety class is not assigned.
NOTE 2 For the safety classification of refrigerant fluids not included in Annex E, see Annex F.
This European Standard covers the hazards mentioned in the introduction.
This European Standard is applicable to new refrigerating systems and modification
of existing refrigerating systems in case the type of refrigerant changed or pressure vessels are replaced. The Part dealing with maintenance, repair, operation, recovery, reuse
and disposal also applies to existing systems. Parties responsible for existing refrigerating
systems should consider the safety and environmental aspects of this European Standard
and implement the more stringent requirements so far as they are reasonably practicable.
Directive 94/9/EC concerning equipment and protective systems intended for use in
potentially explosive atmospheres can be applicable to the type of machine or equipment
covered by this European Standard. The present standard is not intended to provide
means of complying with the essential health and safety requirements of Directive
94/9/EC.
