Refrigeration systems and heat pumps. Flexible pipe elements, vibration isolators, expansion joints and non-metallic tubes. Requirements and classification Ingestion-build-132972 It is not applicable to1 Scope This International standard describes requirements, design and installation of flexible pipe elements (e. g., metallic flexible pipe, metallic flexible tube, vibration isolator, expansion joint) and non metallic tube used in the refrigerant circuits of refrigerating systems and heat pumps. It also describes the requirements to qualify the tightness and permeability of non metallic tubes (e. g., plastic) used in evaporating and or condensing
