Warning This British Standard, which is identical with E
9、N IS0 13846:2000, does not necessarily detail all the precautions necessary to meet the requirements of the Health and Safety at Work etc. Act 1974 and subsequent legislation. Attention should be paid to any appropriate safety precautions and the method should be operated only by trained personnel.

25、or the long-term leaktightness of end-load-bearing and non-end- load-bearing mechanically jointed assemblies and joints between fittings, ancillaries, valves and thermoplastics pressure pipes, including integral pipe joints. This method is applicable to joints where similar or different materials ar
26、e connected, where sealing mechanisms include elastomeric sealing rings or adhesives. This method is applicable in addition to the hydrostatic pressure tests for materials and components. 2 Principle The test simulates expansion of the joint area due to creep. This is related to the permissible work
27、ing conditions for 50 years and based on the properties of the components assembled. The leaktightness of the joint) is tested as an assembly comprising either: a) at least one fitting joined to pipes; or b) an ancillary component or a valve joined to pipes; or c) a pipe-to-pipe joint. The test is c
28、arried out for at least 1000 h at ambient temperature and at the maximum allowed working temperature for the piping system for which the assembly or joint is intended to be used. The test piece and its joint) are subjected to a specified internal hydrostatic water pressure at a specified temperature
29、 for the period of time (1000 h or more) specified in the referring standard. Additional reinforcement of the joint area is not permitted for this test. It is assumed that the following test parameters are set by the standard making reference to NOTE this standard: a) the minimum test period under p
30、ressure, .e. 1000 h or more (see clause 2 and 5.4); b) the free length, i, of the pipe sections under test (see 4.1); c) the number of test pieces (see 4.2); d) the test temperature (e.g. ambient or maximum allowed working temperature) (see 5.2); e) the test pressure (see 5.3). 3 Apparatus 3.1 Ambie
