It is also for use for the revision or amendment of other national standards as practicable, but it should not be presumed to apply to any existing standard or specification which contains or makes reference to a Merent test method until that standardspecif

O BSI 1996 CEN EN81053 95 m 3404589 0137220 713 m 1 Scope This standard specifies a test method for watertightness of: a) joints of thermoplastics piping systems for non-pressure applications; b) thermoplastics fabricated products made from more th
22、an one piece for non-pressure applications. 2 Principle A test assembly comprising either a fabricated product or an assembly of pipes and/or fittings is subjected to a given internai hydrostatic pressure for a given period during which the leaktightness of the fabricated product or the joint is ver
23、ified by inspection. NOTE. It is assumed that the following test parameters are set by the standard making reference to this standard a) the sampling procedure (see 4.1); b) the number of test pieces (see 4.2). 3 Apparatus 3.1 End-sealing devices, having a size and using a sealing method both approp
24、riate to the type of joint under test. The devices shall be restsallied in a manner that does not exert longitudinal forces on the joint assembly and that prevents the devices or the assembly under test from separating under pressure. The weight of the devices shall not be allowed to influence the a
25、ngular deflection to be applied (see 6.2). 3.2 Hgdmstatic pressure source, connected to one end of at least one end-sealing device, capable of applying the requjred pressure gradually and evenly in accordance with 6.4 and then of keeping it constant to +2 -1 (see clause 6). 3.3 Bleed valve, capable
26、of venting air when hydrostatic pressure is applied to the test piece. 3.4 Pressure measuring o!mice, Capable of checking conformity to the required test pressure (see 3.2 and clause 6). % for the duration of the test required 4 lst pieces 4.1 Preparation The test piece shall comprise either a fabri
27、cated fitting or an assembly of (a) pipe section) (with or without sockets) and/or fitting) including at least one joint of the type under test (see figure 1). To assist air removal, the test piece may be inclined by up to 12“. The assembly of the joint) shall be carried out in accordance with the m
28、anufacturers instructions. The assembly shall comprise the combination of the smallest available spigot end and the largest available socket or socket groove diameter within the applicable tolerance(s) and obtained by sampling in accordance with the referring standard. The relevant chneters of the s
29、elected spigot(s) and socket) shall be measured and recorded Page 3 EN 1053 : 1995 4.2 Number The number of test pieces shall be as specied in the referring standard. 6 Procedure 6.1 Carry out the following procedure at an ambient temperature of (23 5) “C using cold tap water without permitting any
30、condensation on the surface of the test piece. 6.2 Mount the test piece in the apparatus. If the joint to be tested permits angular deflection, arrange the test assembly so that the joint(s) under test is (are) subject to the (their) maximum angular deflection, as declared for the joint by the manuf
31、acturer, for the axes of the components thus joined. 6.3 When testing in accordance with 6.4 and 6.6, monitor the test piece for and record any evidence of leakage. 6.4 Introduce water into the test piece, while bleeding off ali air, and apply the hydrostatic pressure as follows: a) accelerated proc
32、edure for fabricated products: unless otherwise specified in the referring standard, apply an hydrostatic pressure of 0,5 bar (50 kPa) and maintain it for at least 1 min. b) assemblies of pipes and/or fittings which are not fabricated: raise the hydrostatic pressure smoothly over a period of not gre
33、ater than 15 min to 0,5 bar (50 kPa) and maintain that pressure for at least 15 min 6.6 Depressurize, drain and dismantle the test piece. Inspect for and record any changes in the appearance of the components tested. 6 Test report The test report shall include the following information: a) a referen
34、ce to this standard and to the referring standard; b) the identification of the components (e.g. fitting(s), pipe), sea) comprising the joint(s) under test and their respective diameters, in millimetres (see 4.1); c) the ambient temperature (see 6.1), in degrees Celsius; d) the test pressure, in bar
35、s; e) the length of time under pressure, in minutes; f) if applicable, the angle of deflection applied to the joint (see 6.2); g) a statement, that the joint did not leak or, if any, a report of signs of leakage or rupture, their position(s) and the pressure at which they occurred; h) any changes in
36、 the appearance of the components of the test piece(s) during the test, or immediately afterwardq i) any factors which may have affected the results, for example, such as any incidents or any operating details not specified in this standard j) the dak of the test.
