25、 a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represen

26、ted on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are dr

27、afted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International S

28、tandard requires approval by at least 75 % of the member bodies casting a vote.

30、moplastics piping systems for soil and waste discharge inside buildings Test method for airtightness of joints 1 Scope This International Standard specifies a method for testing the airtightness of joints of thermoplastics piping systems for soil and waste discharge inside buildings. 2 Principle A t

31、est assembly of pipes and/or fittings is subjected to a given internal air pressure for a given time 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 referring standard: a) the sampling procedure (see 4

32、.1 and Clause 5); b) the number of test pieces (see 4.2). 3 Apparatus 3.1 End-sealing devices, having a size and using a sealing method that are appropriate to the type of joint assembly under test. The devices shall be restrained in such a manner that does not exert longitudinal forces on the joint

33、 assembly and prevents the devices or the assembly under test from separating under pressure. The mass of the devices shall not be permitted to influence the angular deflection to be applied (see 5.8). 3.2 Air pressure source, connected via a shut-off valve to one end of at least one end-sealing dev

34、ice, 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 valve to at least one end-sealing d

35、evice to admit water to the appropriate level within the test piece (see Figure 1). BS EN ISO 13255:2017ISO 13255:2010(E) 2 ISO 2010 All rights reserved4 Test pieces 4.1 Preparation of test pieces The test piece shall comprise an assembly of (a) pipe section(s) (with or without sockets) and/or fitti

36、ng(s), one part of the test piece being a pipe or a fitting with a spigot mounted in two clamped blocks (see Figure 1). Dimensions in millimetres Key 1 fixed points 2 sealing plug with water outlet and end restraint (see 3.1) 3 loose bushes enabling all sizes of pipes to be accommodated on the same

Figure 1 Typical arrangement One end o

38、f 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 ends with plugs, one of which has a centrally mounted water outlet and shut-off valv

39、e (see Figure 2). 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 spigot end and the largest available socket or socket groove diameter within the applicable tolerance(s) and ob

40、tained by sampling in accordance with the referring standard. The relevant diameters of the selected spigots and sockets shall be measured and recorded. 4.2 Number of test pieces The number of test pieces shall be specified in the referring standard.

42、with 5.4 to 5.8, monitor the joint for and record any leaks which are evident by the formation of bubbles of soap solution (see 5.4) and 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

43、. Afterwards, remove any excess, dripping 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 and then the water outlet va

44、lve. 5.7 Open the air inlet valve and increase the internal air pressure to (0,1 0,01) bar1)using air at the temperature specified in 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 t

45、he maximum angular deflection, as stated by the manufacturer for the specific 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 c
