23、ermitted without license from IHS -,-,- v Introduction Tests for determining resistance to internal pressure are essential for assessing the properties and durability of thermoplastics piping system parts. In fact, they constitute a basis for determining short-term and long-term characteristics. Man
24、y International Standards contain requirements for the determination of the resistance to pressure of pipes, fittings or assemblies. All these documents describe the equipment for pressurizing the different test pieces considered as well as the testing procedure and the test report. In order to avoi
25、d unnecessary repetition, it is desirable to group together all these documents and to establish one International Standard divided into several parts. ISO 1167-1 contains a description of the equipment used to pressurize test pieces, the testing procedure to be applied and the test report. ISO 1167
26、-2, ISO 1167-3 and ISO 1167-4 describe the method of preparation of test pieces corresponding to each case considered: pipes, components or assemblies.

29、nce to internal hydrostatic pressure at a given temperature of thermoplastics pipes, fittings and piping systems for the transport of fluids. The method accommodates water-in-water, water-in-air and water-in-liquid tests. 2 Normative references The following referenced documents are indispensable fo

Throughout the test, the test pieces are kept
36、in an environment at a specified constant temperature: this is either water (“water-in-water” test), another liquid (“water-in-liquid” test) or air (“water-in-air” test). The following test parameters shall be specified by the standard or specification making reference to this part of ISO 1167: a) t
37、he type of end cap to be used (see 5.1 and ISO 1167-2:2006, 4.1); b) the test temperature; c) for evaluation purposes, the SDR or S-series or size of pipe or fitting to be used; d) the number of test pieces; e) the test pressure, p, or the circumferential (hoop) stress, , to be induced by the test p
38、ressure; f) the type of test, i.e. “water-in-water”, “water-in-liquid” or “water-in-air”; g) the duration of the test under pressure and the criteria for a failure; h) the requirements, or patterns of requirements, if any, which determine the initiation of additional testing. 5 Apparatus 5.1 End cap
39、s, fixed to the ends of the test piece. By means of an appropriate system or procedure, end caps shall allow sealing and connection to the pressurizing equipment and shall allow purging of the air before testing. The end caps shall be one of the following types. Type A: fittings rigidly connected to
40、 the test piece but not to each other, and hence transmitting the hydrostatic end thrust to the test piece, e.g. as shown in Figure 1, or equivalent. They may comprise flanged plates on the ends of a large diameter pipe, optionally fused when flanges, caps, plugs or plates are of a compatible materi
41、al to the test pieces. Type B: sockets, made of metal, fitted with joints ensuring sealing onto the external surface of the test piece and connected to one another, and hence not transmitting the hydrostatic end thrust to the test piece. They may comprise one or more metal rods, see Figure 1, allowi
42、ng sufficient longitudinal movement at the ends of the test pieces, to avoid buckling due to thermal expansion. If external rods are used, contact of the outside surface of the test piece with one or several rods shall be avoided during the test. In this case, the test shall be disregarded. Other th
43、an toothed grips, any sharp edges which would come into contact with the outside surface of the pipe shall be rounded off. The constituent material of the end cap might have an adverse effect on the test piece under test and such materials should therefore be avoided as far as possible. For testing
44、of components, the end caps shall be replaced by pressure-tight devices as specified in ISO 1167-3. End caps of type A shall be used for determination of the long-term hydrostatic strength of materials in accordance with ISO 9080. NOTE It is recognized that times to failure can be different dependin
45、g upon the type of end caps used.

46、Type A b) Type B Figure 1 Examples of end caps for internal pressure testing 5.2 Tank, filled with water or other liquid, kept at a constant temperature as specified in the referring standard to within 1 C, or oven, the temperature of which shall be kept at the specified value to within 2 1 + C. Whe
47、n an environment other than water is used, necessary precautions shall be taken, in particular those concerning safety and any interaction between liquid and the material(s) of the test piece. When environments other than water are used, tests which are intended to be comparative shall be carried ou
48、t in the same environment. As the results are strongly influenced by temperature, the tolerance on temperature should be kept as small as possible within the specified limits e.g. by using forced circulation of the fluid. When testing in air, the pipe surface temperature should be checked in addition to the air
