ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.The procedure

It covers methods of test for the leaktightness and resistance to damage of the joint only, when subject to specified combinations of longitudinal extension (draw), angular movement (angular deflection), compression (deformation) perpendi

This International Standard is applicable to joints for either pressure or non-pressure applications.NOTE The joints tested in accordance with this International Standard are subjected to conditions which measure their ability to function and thereby pro
