5、ion of this standard is 2017-03-01. National foreword This standard includes safety requirements. This document (EN 378-3:2016) has been prepared by Technical Committee CEN/TC 182 “Refrigerating systems, safety and environmental requirements” (Secretariat: DIN, Germany). The responsible German body
6、involved in its preparation was DIN-Normenausschuss Kltetechnik (DIN Standards Committee Refrigeration Technology), Working Committee NA 044-00-01 AA Sicherheit und Umweltschutz. The scope of this standard series does not only affect questions of system safety, but also different aspects of occupati
7、onal health and construction law. This includes access categories of systems, limit values of refrigerants or protection of persons in cold rooms. The relevant applicable legislation includes, e.g., the Gefahrstoffverordnung (Hazardous Substances Ordinance), the Arbeitsstttenverordnung (Workplaces O
8、rdinance), the Betriebssicherheitsverordnung (Ordinance on Industrial Safety and Health) and, where appropriate, building regulations of the Federal States of Germany. By meeting the requirements of standards, the user cannot assume, without additional verification, that the relevant regulations and
9、 aforementioned laws for refrigerating systems and heat pumps are observed. Amendments This standard differs from DIN EN 378-3:2012-08 as follows: a) it has been harmonized with ISO 5149:2014 and ISO 817:2014 as far as possible; b) the term “special machinery room” has been replaced by “separate ref
10、rigeration machinery room”; c) the requirements for 2L refrigerants have been considered; d) Clause 6 “Requirements for alternative provisions” has been included to supplement the information in EN 378-1:2016, C.3; e) the requirements for sprinkler systems have been modified.

DIN EN 378-3:2017-03 EN 378-3:2016 (E) 7 1 Scope This European Standard specifies the requirements for the safety of persons and property, provides guidance for the protection of the enviro
37、nment 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 3 of the European Standard is applicable to the installation site (plant
38、 space and services). It specifies requirements on the site for safety, which may be needed because of, but not directly connected with, the refrigerating system and its ancillary components. This standard applies: a) to refrigerating systems, stationary or mobile, of all sizes except to vehicle air
39、 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 capacit
40、y. Systems using refrigerants other than those listed in of EN 378-1:2016, Annex E are not covered by this standard. This standard does not apply to goods in storage. This standard is not applicable to refrigerating systems which were manufactured before the date of its publication as a European Sta
41、ndard 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 s
42、ite. This standard also applies in the case of the conversion of a system for another refrigerant type, in which case conformity with the relevant clauses of parts 1 to 4 of the standard shall be assessed. 2 Normative references The following documents, in whole or in part, are normatively reference
