Comments to ISO 15348:

This International Standard deals only with the terminology and the general rules for the design, manufacture, control and type testing of metal expansion joints. As it is not harmonized to the European Pressure Equipment Directive (97/23/EC), PED, the presumption of conformity to the directive is not give. It can only be used for general concerns as fare as it does not conflict the PED.
