Plastics piping systems. Multilayer M (metal) pipes. Test method for strength of the weld line in the metal layer and bonding between layers by use of a cone shop-only This document does not apply1 Scope This Technical Report specifies a method for testing the strength of the weld line in the metal layer and the adhesion between the different layers of multilayer M pipes by the use of a cone. NOTE 1 Acceptance of any inner layer made from a specific grade of material is subject to the relevant product standard or system standard and the requirements detailed in that standard. NOTE 2 The test can be used as a product verification test during
