23、ethod for preparation of extruded, or injection-moulded tubular, test pieces used to determine the resistance of thermoplastics pipes to internal hydrostatic pressure according to ISO 1167-1. 2 Normative references The following referenced documents are indispensable for the application of this docu
24、ment. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

25、l pressure Part 1: General method ISO 3126, Plastics piping systems Plastics components Determination of dimensions 3 Principle Pipe test pieces may be obtained by extrusion or injection-moulding. The extruded test pieces are used for material and pipe testing, whereas the injection-moulded tubular
26、test pieces are used for testing injection moulding materials only. The injection-moulded tubular test pieces make it possible to determine the time-related behaviour of the injection moulding material for fittings under hydrostatic pressure and under the same conditions as specified for extruded pi
27、pes. It is possible to extrapolate the results in accordance with a method such as that specified in ISO 9080 in order to determine the MRS (minimum required strength) and to classify the material using ISO 12162. The tubular test pieces also make it possible to verify individual points on previousl
28、y established stress/time regression curves as a minimum material test requirement. NOTE If the compound used for the injection-moulding of components can also be extruded, then its time-related behaviour can be investigated using either injection-moulded or extruded tubular test pieces. After condi
29、tioning, test pieces consisting of a portion of pipe sufficient to provide the required free length as a function of the diameter of the pipe are subjected to a specified internal hydrostatic pressure or stress for a specified period of time or until the test piece(s) fail(s), in accordance with ISO
30、 1167-1. The number of test pieces, conditioning and details of the test report are given in ISO 1167-1.

32、O 3126, e.g. Pi-tape. 5 Test pieces 5.1 Extruded test pieces 5.1.1 Free length The free length, l0, of the pipe between the end caps shall be at least three times the nominal outside diameter dn, with a minimum of 250 mm. If, for pipes with dn greater than 315 mm, the specified minimum free length c
33、annot be achieved, a shorter free length may be chosen with a minimum of two times dn, unless otherwise specified in the referring standard or specification. 5.1.2 Total length For type B end caps (see ISO 1167-1:2006, 5.1), the total length of the test piece shall be such that movement of the test
34、piece between the end caps is accommodated during the test, thus making allowance for thermal expansion. 5.2 Injection-moulded tubular test pieces Injection-moulded test pieces shall conform to the following requirements for the dimensions shown in Figure 1. The nominal outside diameter dn of the te
35、st pieces shall be between 25 mm and 110 mm inclusive. The wall thickness will depend on the material concerned. The free length l0 of the test pieces, excluding the ends, shall be 3dn, except for test pieces dn W 50 mm, for which the minimum free length shall be 140 mm. Injection-moulded test piece
36、s with a longitudinal fusion line and both ends open should preferably be used for comparative and investigative purposes only. The injection-moulding parameters can strongly influence the stresses in the injection-moulded test piece. 5.3 Measurement of dimensions If necessary for the calculation of
37、 the test pressure (see ISO 1167-1:2006, 7.2), find and determine, in accordance with ISO 3126, the minimum wall thickness and the mean outside diameter of the free length of the test piece, using apparatus conforming to 4.2 and 4.3. These measurements shall be used for further calculations. The rou
38、nding up procedure of ISO 3126 shall not be applied. 6 Test report Record the information required in order to comply with ISO 1167-1:2006, Clause 11 and include the method of manufacture of the test piece, i.e. by extrusion or by injection moulding.
