Abstract
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 sides of refrigerating systems and heat
pumps.
This International standard does not apply to flexible pipes that are only occasionally stressed
beyond the
elastic limit (e.g., during repair work), or to joints that are free to rotate or hinge.
