The static components concerned are, in particular, the fittings the bursting discs, the flanged or fitted assemblies. This document is intended to characterise their tightness, stresses met during their operations, following the fitting procedure specified by the manufacturer, and to specify the minimal list of operation to be provided by the supplier of a component to the person in charge of carrying out this procedure. It specifies the maximal leakage of the component. It applies to the static components used in the refrigerating installations, including those with seals, whatever their material and design are.
