Heat pumps (ICS 27.080), Refrigerating technology (ICS 27.200)

Draft of Egyptian standard ES 5056-4 for "Refrigerating systems and heat pumps — Safety and environmental requirements — Part 4: Operation, maintenance, repair and recovery" (28 page(s), in Arabic)

This part of this draft standard specifies requirements for safety and environmental aspects in relation to operation, maintenance and repair of refrigerating systems and the recovery, reuse and disposal of all types of refrigerant, refrigerant oil, heat transfer fluid, refrigerating system and part thereof.

These requirements are intended to minimize risks of injury to persons and damage to property and the environment resulting from improper handling of the refrigerants or from contaminants leading to system breakdown and resultant emission of the refrigerant.

Sub clauses 4.1.1, 4.1.2, 4.3, 5.1.1 to 5.1.4, 5.2, 5.3.1, 5.3.3 and 6.6 of this part of ES 5056-4 are not applicable to unitary systems having a power cord, being factory sealed, and in conformance with IEC 60335 series.

Worth mentioning is that this draft standard is technically identical with ISO 5149-4:2014.
