The w
21、ork 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 represented on that committee. International organizations, governmental and non-govern
22、mental, 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 drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The
23、 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 Standard requires approval by at least 75 % of the member bodies casting a vote.

26、ermoplastics piping systems for non-pressure underground drainage and sewerage Test method for resistance to combined temperature cycling and external loading 1 Scope This International Standard specifies two methods for testing pipes and fittings or joints for plastics piping systems intended for u
27、se in underground drainage and sewerage systems for their resistance to deformation and leakage, when subjected to sustained external loading in conjunction with the passage of hot water. Method A involves temperature cycling, by passing hot water and cold water alternately, and is applicable to pip
28、es and associated fittings having a mean outside diameter demu 190 mm. Method B involves passing hot water only, except at intervals specified for measurement of internal deflection, and is applicable to pipes and associated fittings having a mean outside diameter 190 mm 190 mm Pass water at a tempe
29、rature, T1, of (50 2) C constantly through the test piece. The temperature of the water, T2, measured at the outlet hot water sensor, shall be (50 2) C, unless otherwise specified in the referring standard. NOTE Surface temperatures are not measured. Unless otherwise specified in the referring stand
30、ard, maintain the flow for 192 h. The hot water temperature may be recorded at the outlet hot water sensor, continuously during the test. 7.3 Assessment 7.3.1 Assessment of initial deflection and leaktightness Before removing the force on the loading plate, and unless 7.3.3 applies, proceed as follo
31、ws. a) Locate, measure and record the vertical inside diameter, d2, or the reference dimension at the position at which d1was measured. b) Seal the pipe ends, fill the assembly with water at a temperature of (17 5) C and, after a conditioning period of 15 min, apply a hydrostatic pressure of 0,35 ba
32、r, for a period of 15 min whilst monitoring the pressure and during which the pressure shall not fall below 0,3 bar. The vertical deflection may be measured continuously during the test. 7.3.2 Control of deflection, weld line and cracks After the leak-tightness test and within 24 h after removal of
33、the force, and unless 7.3.3 applies, measure the local deflections in the test piece as follows. a) Measure the evenness of the bottom of the test piece from the outside in the direction of the longitudinal axis, by placing the straight edge against the bottom of the test piece, without contacting a
34、ny raised structural features of the test piece, and measuring the greatest gap between the straight edge and the bottom of the test piece; b) Measure deviations in the bending radius of the test piece by using a gauge not less than 2 mm thick in the shape of a cylinder with the axis of the gauge al
35、igned with the longitudinal axis of the test piece and the convex part of the gauge turned in the direction of the perimeter along the test piece which was subjected to water flow; c) Drain, recover and dismantle the test piece and inspect the test piece components for any damage visible without mag
36、nification. In weld line zones, if any opening is visible, break it open and measure the greatest depth of the crack in the fracture surface induced by the exposure to hot water. Record the observations and the crack depth(s), as applicable. 7.3.3 Alternative deflection measurement Alternatively, 7.
37、3.1 a), 7.3.2 a) and 7.3.2 b) may be replaced by the following procedure.

40、ition at which d1was measured (see 7.3.1). 9 Test report The test report shall include the following information: a) a reference to this International Standard, i.e. ISO 13260:2010, and the referring standard; b) the identity of the fitting or pipe under test, including its (their) nominal size(s);

47、t as applicable: a) the maximum vertical deflection after the test is completed, but before the load is released (see 7.3.1) should be 8 % for products of PVC-U and ABS and 9 % for products of PE and PP see item f). b) the tightness test as specified in item b) of 7.3.1 should allow no leakage. c) w
48、hen determined in accordance with item a) of 7.3.2 the deviation from evenness in the bottom caused by the test should be maximum 3 mm see item f). d) when determined in accordance with item b) of 7.3.2 the radius in the bottom should be at least 80 % of the original see item f). e) when determined in accordance with item c) of 7.3.2 any opening of a weld line should be u 20 % of the wall thickness at that point. f) items a), c) and d) may be replaced by passing a hard ball as specified in 7.3.3. In that case, the ball should easily pass the test assembly. BS EN I
