This document specifies a method for evaluation of the ductility of the fusion joint interface of assemblies of polyethylene (PE) pipe and electrofusion saddles, intended for the conveyance of fluids.




NOTE 1 The applicability of this method depends upon the design of the saddle. If not applicable, the strip-bend test according to ISO 21751[1] is considered an alternative.

NOTE 2 This method is considered applicable for heated tool saddles, but no experience is available with the experts of the working group.
