Each member body interested in a subject for which a technical committee has been established has liaison with isO, also take part in the work. IsO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Attention is drawn to the possibility that some of the elements of this International Standard may be the subject of patent rights.

The method is applicable to polyethylene (PE) tapping tees, PE/metal transition fittings and PE branch saddles: intended for use with PE pipes having a nominal outside diameter de ≤ 63 mm. NOTE 2 Principle A bending-load application system imposes a vertical displacement perpendicular to the axis of a pipe which is along the pipe. Each complete loading cycle consists of the following stages: a) position. b) The pipe remains at rest in the neutral position for 10 s. c) The load application system deflects the PE
