38、at of which is held by DIN. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by May 2017, and conflicting national standards shall be withdrawn at the latest by May 2017. Attention is drawn to the pos

This document supersedes EN 378-1:2008+A2:2012. EN 378 consists of the following parts under the general title “Ref

40、rigerating systems and heat pumps Safety and environmental requirements”: Part 1: Basic requirements, definitions, classification and selection criteria; Part 2: Design, construction, testing, marking and documentation; Part 3: Installation site and personal protection; Part 4: Operation, maintenanc

41、e, repair and recovery. The main changes in part 1 with respect to the previous edition are listed below: harmonization as far as possible with ISO 5149:2014 and ISO 817:2014; adapt definitions for the purpose of harmonizing EN 378-2:2016 with PED. Following detailed changes are worth noting: modifi

42、cation of the term “special machinery room” to “separate refrigeration machinery room” and adapt the definition in view of combustion equipment; modifications/inclusion of definitions for “part of the refrigerating system” (3.1.8), “pressure equipment” (3.1.20) and “pressure vessels” (3.4.8) in view

43、 of PED; movement of the location classification from Annex C to 5.3; rewording of the system examples in 5.3 to make the relation clear with location classification; replacement of Annex F (safety group) classifications by 5.2; modification of the approach to determine the refrigerant charge of a r

44、efrigeration system. The charge limit requirement is decided based on the most stringent refrigerant charge that results from the calculation based on toxicity and the calculation based on flammability. To this purpose, the tables in Annex C are modified. Table C.1 contains requirements based on tox

45、icity classes, Table C.2 contains requirements based on flammability classes; BS EN 378-1:2016g8g17g3g885g889g890g487g883g483g884g882g883g888g3g525g8g5264BS EN 378-1:2016EN 378-1:2016 (E) 5 addition of the refrigerant classes as determined in ISO 817 to toxicity classes A, B and flammability classes
