Refrigerating systems and heat pumps - Safety and environmental requirements - Part 1: Basic requirements, definitions, classification and selection criteria

This European Standard specifies the requirements for the safety of persons and property, provides guidance for the protection of the environment and establishes procedures for the operation, maintenance and repair of refrigerating systems and the recovery of refrigerants.
The term "refrigerating system" used in this European Standard includes heat pumps.
This part of EN 378 specifies the classification and selection criteria applicable to refrigerating systems. These classification and selection criteria are used in parts 2, 3 and 4.
This standard applies:
a)   to refrigerating systems, stationary or mobile, of all sizes except to vehicle air conditioning systems covered by a specific product standard e.g. ISO 13043;
b)   to secondary cooling or heating systems;
c)   to the location of the refrigerating systems;
d)   to replaced parts and added components after adoption of this standard if they are not identical in function and in the capacity;
Systems using refrigerants other than those listed in Annex E of this European Standard are not covered by this standard.
Annex C specifies how to determine the amount of refrigerant permitted in a given space, which when exceeded, requires additional protective measures to reduce the risk.
Annex E specifies criteria for safety and environmental considerations of different refrigerants used in refrigeration and air conditioning.
This standard is not applicable to refrigerating systems and heat pumps which were manufactured before the date of its publication as a European Standard except for extensions and modifications to the system which were implemented after publication.
This standard is applicable to new refrigerating systems, extensions or modifications of already existing systems, and for existing stationary systems, being transferred to and operated on another site.
This standard also applies in the case of the conversion of a system to another refrigerant type, in which case conformity to the relevant clauses of parts 1 to 4 of the standard shall be assessed.
Product family standards dealing with the safety of refrigerating systems takes precedence over horizontal and generic standards covering the same subject.

This draft amendment is submitted to CEN members for enquiry. It has been drawn up by the Technical Committee CEN/TC 182.

This draft amendment A1, if approved, will modify the European Standard EN 378-1:2016. If this draft becomes an amendment,

CEN members are bound to comply with the CEN/CENELEC Internal Regulations which stipulate the conditions for inclusion of

this amendment into the relevant national standard without any alteration.

This draft amendment was established by CEN in three official versions (English, French, German). A version in any other

language made by translation under the responsibility of a CEN member into its own language and notified to the CEN-CENELEC

Management Centre has the same status as the official versions.

The vapour density, molecular mass, normal boiling point, ODP and GWP (AR5) are not part of this European Standard and are provided for information purposes only.

The preferred chemical name is followed by the popular name in parentheses.
Sublimation temperature. Triple point is −56,6 °C at 5,2 bar.
Determined according to 5.2 of this standard.
Adopted under the Montreal Protocol.

Data from IPCC Assessment Report V (AR5); for HCs which are not included in AR5, data from F-Gas regulation N° 517/2014.

Acute-Toxicity Exposure Limit (ATEL) or Oxygen Deprivation Limit (ODL), whichever is lower values taken from ISO 817.

Lower Flammability Limit.
Practical limit values are grandfathered according to 5.2.

ATEL/ODL values are changed in comparison to EN 378-1:2008+A2:2012 according to data from ISO 817.

No cardiac NOEL value available, value determined according to ISO 817.

Data from European F-Gas regulation N° 517/2014; for CFCs and for HCFCs which are not included in F-Gas regulation N° 517/2014, data from IPCC assessment report

IV.
PED = Pressure Equipment Directive 2014/68/EU.

According to the test conditions in ISO 817, the refrigerant is classed as 2L, however the PED fluid group is 2, based on CLP Regulation (EC) 1272/2008.
