Requirements 8.1 Longitudinal Reversion—When tested in accordance with ISO 15874-2, at the conditions given in Table 8, the mean relative change in pipe length shall not exceed 2 %. 8.2 Melt Flow Rate (MFR) of Pipe and Fittings—When tested in accordance with D 1238, the MFR of specimens taken from the finished pipe or…
C.1 GeneralThe test shall consist of measuring the force required for peeling the coating from the metal substrate of the pipe at a constant rate of pull.C.2 EquipmentC.2.1 Tensile testing machine, capable of recording the peel force with a 5 % reading accuracy, thatoperates at a rate of pull of 10 mm/min, as shown in…
6.4 Pipe Stiffness and Flattening:6.4.1 Well Casing Pipe—The well casing pipe shall have a pipe stiffness at 5 % deflection equal to that shown in Table 6 and Table 7 and shall deflect 60 % of the original diameter (flattening) without cracking, rupture, or other visible evidence of failure when tested in accordance with Test…
5 Apparatus5.1 GeneralSee ISO 527-1:2012, Clause 5, specifically 5.1.1 to 5.1.4.5.2 ExtensometerFor this part of ISO 527, a gauge length of 75 mm is preferred when a multipurpose test specimen is used.A gauge length of 50 mm is also acceptable for quality-control purposes or where specified.If strains are recorded only on one side of the…
4 PrincipleA test specimen is weighed and subsequently calcinated at a defined temperature. The specimen is thenreweighed and the non-combustible matter content (glass + filler) obtained by determining the difference in mass of a test specimen before and after calcination in one of the following ways:a) In the case of materials containing no fillers the…
6 Apparatus6.1 Fig. 1 shows an example of the test apparatus that can be used in the performance of this test method. The apparatus requires a pressure vessel rated to a minimum of 690 kPa (100 psi). The vessel diameter should be 600 mm3. Other size vessels may be used but it is up to…
