11、porated into BS 2782 Methods of testing plastics: Part 11: Thermoplastics pipes, fittings and valves, as Method 1112B : 1996 for association with related test methods for plastics materials and plastics piping components. This test method has been prepared for reference by other standards under prep

12、aration by CEN for specification of plastics piping systems and components. It has been implemented to enable experience of the Method to be gained and for use for other fresh applications. It is also for use for the revision or amendment of other national standards as practicable, but it should not

13、 be presumed to apply to any existing standard or specification which contains or makes reference to a different test method until that standard/specification has been amended or revised to make reference to this Method. This Method supersedes BS 2782 : Part 11 : Method 1112A : 1989, which becomes o

25、ndard has been prepared by the Technical Committee CEN/TC 155, Plastics piping systems and ducting systems, of which the secretariat is held by NNI. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by

26、 April 1996, and conflicting national standards shall be withdrawn at the latest by April 1996. According to CEN/CENELEC Internal Regulations, the following countries are bound to implement this European Standard: Austria, Belgium, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy,

27、Luxembourg, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and the United Kingdom. This standard is based on annex B Watertightness test of ISO 3633 : 1991 Unplasticized poly(vinyl chloride) (PVC-U) pipes and fittings for soil and waste discharge (low and high temperature) systems inside

28、buildings Specifications, published by the International Organization for Standardization (ISO). It is a modification of annex B for reasons of applicability to other plastics materials and/or other test conditions and alignment with texts of other standards on test methods. The modifications are: n

29、o material is mentioned; test parameters, except those common to all plastics, are omitted; no diameter limit is included; no material-dependent requirements are given; editorial changes have been introduced; the method has been extended to cover quick testing of fabricated products made from more t

30、han one piece. The material-dependent test parameters and/or performance requirements are incorporated in the system standard(s) concerned. This standard is one of a series of standards on test methods which support system standards for plastics piping systems and ducting systems.Page 3 EN 1053 : 19

31、95 BSI 1996 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 than one piece for non-pressure applications. 2 Principle A test assembly comprising either

32、a fabricated product or an assembly of pipes and/or fittings is subjected to a given internal hydrostatic pressure for a given period during which the leaktightness of the fabricated product or the joint is verified by inspection. NOTE. It is assumed that the following test parameters are set by the

33、 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 appropriate to the type of joint under test. The devices shall be restrained in a manner that d

34、oes 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 angular deflection to be applied (see 5.2). 3.2 Hydrostatic pressure source, connected to o

35、ne end of at least one end-sealing device, capable of applying the required pressure gradually and evenly in accordance with 5.4 and then of keeping it constant to within % for the duration of the test required 21 +2 (see clause 5). 3.3 Bleed valve, capable of venting air when hydrostatic pressure i

36、s applied to the test piece. 3.4 Pressure measuring device, capable of checking conformity to the required test pressure (see 3.2 and clause 5). 4 Test pieces 4.1 Preparation The test piece shall comprise either a fabricated fitting or an assembly of (a) pipe section(s) (with or without sockets) and

37、/or fitting(s) 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(s) shall be carried out in accordance with the manufacturers instructions. The assembly shall comprise the combination of th

38、e 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 diameters of the selected spigot(s) and socket(s) shall be measured and recorded. 4.2 Number

39、The number of test pieces shall be as specified in the referring standard. 5 Procedure 5.1 Carry out the following procedure at an ambient temperature of (23 5) C using cold tap water without permitting any condensation on the surface of the test piece. 5.2 Mount the test piece in the apparatus. If

40、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 manufacturer, for the axes of the components thus joined. 5.3 When testing in accordance with 5.4

41、and 5.5, monitor the test piece for and record any evidence of leakage. 5.4 Introduce water into the test piece, while bleeding off all air, and apply the hydrostatic pressure as follows: a) accelerated procedure for fabricated products: unless otherwise specified in the referring standard, apply an

42、 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 greater than 15 min to 0,5 bar (50 kPa) and maintain that pressure for at least 15 min. 5.5 Depr

43、essurize, 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 reference to this standard and to the referring standard; b) the identification of the components (

44、e.g. fitting(s), pipe(s), seal(s) comprising the joint(s) under test and their respective diameters, in millimetres (see 4.1); c) the ambient temperature (see 5.1), in degrees Celsius; d) the test pressure, in bars; e) the length of time under pressure, in minutes; f) if applicable, the angle of def

45、lection applied to the joint (see 5.2); 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 the appearance of the components of the test piece(s) during the test, or immediately

46、afterwards; 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 date of the test.Page 4 EN 1053 : 1995 BSI 1996 Dimensions in metres A Air outlet B Water inlet C Sealing plug with water inlet, air outl
