It is applicable to all such thermoplastics pipes, regardless of their intended use. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated document (including any amendments) applies. IsO5893,Rubberandplasticstestequipment-Tensile,flexuralandcompressiontypes(constantrateof traverse)Specification Principle 3 Test pieces of specified shape and dimensions are taken from a thermoplastics pipe with a spirally-formed The tensile forces necessary to rupture test pieces, including the seam, are determined using a tensile testing machine under specified conditions. It is assumed that the following test parameter is set by the referring standard: rate of movement of the driven grip (see 4.1 and 8.2). Apparatus 4.1Tensile testing machine, conforming to ISO 5893 for the specified rate of movement of the driven grip It shall be capable of applying the necessary force and travel (see 4.3 and 8.3). 4.2 Grips, for holding the test piece, conforming to IsO 5893, which shall be fixed to the machine in such a way that they move freely into alignment as soon as a
