10、 BSI 1996 BS EN 1054 : 1996 National foreword This British Standard has been prepared by Technical Committee PRI/61 and is the English language version of EN 1054 : 1995 Plastics piping systems Thermoplastics piping systems for soil and waste discharge Test method for airtightness of joints, publish
11、ed by the European Committee for Standardization (CEN). It is incorporated into BS 2782 Methods of testing plastics: Part 11: Thermoplastics pipes, fittings and valves, as Method 1112C : 1996, for association with related test methods for plastics materials and plastics piping components. This test
12、method has been prepared for reference by other standards under preparation 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 ame
13、ndment 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 different test method until that standard/specification has been amended or revised to make reference to this Method. No existing
14、 British Standard is superseded by this Method. Warning note. This British Standard, which is identical with EN 1054 : 1995, does not necessarily detail all the precautions necessary to meet the requirements of the Health and Safety at Work etc. Act 1974. Attention should be paid to any appropriate
15、safety precautions and the method should be operated only by trained personnel. Attention is drawn to the descriptor gas permeability which is misleading. This method is a test for the leaktightness of a joint, it does not give any assessment of permeability through any material. Compliance with a B

23、1995 BSI 1996 Foreword This European Standard was 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
24、or by endorsement, at the latest by April 1996, and conflicting national standards shall be withdrawn at the latest by April 1996.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
25、, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and the United Kingdom. This standard is based on annex C Airtightness test of ISO 3633 : 1991 Unplasticized poly(vinyl chloride) (PVC-U) pipes and fittings for soil and waste discharge (low and
26、high temperature) systems inside buildings Specifications, published by the International Organization for Standardization (ISO). It is a modification of annex C for reasons of applicability to other plastics materials and/or other test conditions and alignment with texts of other standards on test
27、methods. The modifications are: no 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 material-dependent parameters and/or performance requi
28、rements are incorporated in the system standard(s) concerned. No existing European Standard is superseded by this standard. 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 1054 : 1995 BSI 1996 Dime

Typical arrangement 1 Scope This standard specifies a method for testing the airtightness of joints of thermoplastics piping systems for soil and waste discharge i
31、nside buildings. 2 Principle A test assembly of pipes and/or fittings is subjected to a given internal air pressure for a given period during which the leaktightness of the joint is verified by inspection. NOTE. It is assumed that the following test parameters are set by the standard making referenc
32、e 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 assembly under test. The devices shall be restrained in a manner that does not exert lo
33、ngitudinal 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 deflections to be applied (see 5.8). 3.2 Air pressure source, connected via a shut-off valve to one
34、 end of at least one end-sealing device, and capable of maintaining the required pressure within 10 % (see clause 5). 3.3 Pressure measuring device, capable of checking conformity to the required test pressure (see 3.2 and clause 5). 3.4 Water supply and outlet devices, each connected via a shut-off
35、 valve to at least one end-sealing device to admit water to the appropriate level within the test piece (see figure 1). 4 Test pieces 4.1 Preparation The test piece shall comprise an assembly of (a) pipe section(s) (with or without sockets) and/or fitting(s), one part of the test piece being a pipe
36、or a fitting with a spigot mounted in two clamped blocks (see figure 1). One end of the pipe shall be sealed with a plug that has a combined water and air inlet. A fitting or a joint shall be assembled with the open end of the fixed component. The fitting or joint shall then be sealed at all open en
37、ds with plugs, one of which has a centrally mounted water outlet and shut-off valve (see figure 2).Page 4 EN 1054 : 1995 BSI 1996 The assembly of the joint(s) shall be carried out in accordance with the manufacturers instructions. The assembly shall comprise the combination of the smallest available
38、 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 The number of test p
39、ieces shall be as specified in the referring standard. 5 Procedure 5.1 Carry out the following procedure at ambient temperatures of (23 5) C using cold tap water. 5.2 Mount the test piece horizontally in the apparatus (see figure 1). 5.3 When testing in accordance with 5.4 to 5.8 monitor the joint f
40、or and record any leaks which are evident by the formation of bubbles of soap solution (see 5.4) and/or the escape of water. 5.4 Apply a solution of soapy water or equivalent leak-detecting agent around the annular space between the spigot and the mouth of the socket. Afterwards remove any excess, d
41、ripping liquid with a dry cloth. 5.5 Open the water outlet valve and close the air inlet valve. 5.6 Open the water inlet valve. When the assembly is half-full, as indicated by water flow from the outlet, close first the water inlet valve(s) and then the water outlet valve(s). 5.7 Open the air inlet
42、valve and increase the internal air pressure to (0,1 0,01) bar (10 1) kPa using air at the ambient temperature (see 5.1). 5.8 Maintain this pressure for 5 min, then deflect the fitting or joint manually on the spigot end of the clamped component, until their consecutive axes reach the maximum angula
43、r deflection, as declared by the manufacturer for the joint under test. Apply this angular deflection at 0, 90, 180 and 270 (see figure 2), maintaining it for 1 min in each of these directions. 5.9 Depressurize, drain and dismantle the test piece. Inspect for and record any changes in the appearance
44、 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 identity of the components (e.g. fitting(s), pipe(s), seal(s) comprising the joint(s) under test) and their respective diameters, in
45、 millimetres (see 4.1); c) the ambient temperature, in degrees Celsius (see 5.1); d) the test pressure, in bars; e) the length of time under pressure, in minutes; f) if applicable, the angle of deflection applied to the joint (see 5.8); g) a statement, that the joint did not leak or, if any, a repor
46、t 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 afterwards; i) any factors which may have affected the results, such as any incidents or any operating
47、details not specified in this standard; j) the date of the test.Page 5 EN 1054 : 1995 BSI 1996 End elevation (indicating directions of deflection during the test) A Blocks split and held together with wing-nut B Sealing plug C Directions of movement of fitting during test Figure 2.
