EN 1736:2008 Refrigerating systems and heat pumps - Flexible pipe elements, vibration isolators, expansion joints and non-metallic tubes - Requirements, design and installation
This document 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 of non-metallic tubes (e. g. plastic) used in evaporating and/or condensing sides of refrigerating systems and heat pumps. It does not apply to flexible pipes that are only occasionally stressed beyond the elastic limit; e. g. during repair work; or to joints which are free to rotate or hinge.
