13、3267:2010(E) iv ISO 2010 All rights reservedForeword ISO (the International Organization for Standardization) is 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 membe

14、r 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-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Elec

15、trotechnical 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 main task of technical committees is to prepare International Standards. Draft International Standards adopt

16、ed 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. Attention is drawn to the possibility that some of the elements of this document may be the subject of paten

26、 2010 All rights reserved4 Principle A sealed test assembly, comprising an inspection chamber or manhole base with a minimum height of 300 mm above the top of the main channel, is placed free standing, or buried in a test box on a 100 mm sand or granular bed and covered with granular backfill to a l

27、evel of minimum 300 mm above the top of the outlets and inlets of the main channel(s). In some cases, the first section of the riser may be required in order to achieve the minimum height of 300 mm. The assembly is then subjected to a constant internal negative pressure, specified by the product or

28、system standard, for a specified time at a temperature of between 15 C and 25 C or as otherwise specified in the product standard. Alternatively, the pressure difference can be achieved by exposing the test assembly to a constant positive external hydrostatic pressure of the same numeric value as th

29、at specified by the product or system standard. The assembly is submerged under water in a closed tank for a specified time at a temperature of between 15 C and 25 C or as otherwise specified in the product standard. During the test, the assembly may be monitored by measuring increasing deflections

30、with time as defined in the product standard. At the end of the test, the chamber base/manhole is visually checked for cracking or other defects likely to impair the performance of the inspection chamber or manhole. 5 Apparatus 5.1 Test box, large enough to accommodate the test assembly, including t

31、he first 300 mm of riser shaft above the top of the outlet and inlets of the main channel, such that at each side there is a free space of 300 mm minimum between the test assembly and the side/top of the test box. 5.2 Backfill material, to cover the test assembly in the box, conforming to ENV 1046:2

32、001, Annex A. Backfill material shall be in accordance with the minimum specification of the manufacturer. 5.3 Sealable water tank or pressure vessel, with internal dimensions capable of accommodating the test assembly to ensure all-round clearance and a lockable lid allowing access to the open top

33、of the inspection chamber or manhole. The water tank or pressure vessel shall be such that the test assembly is not able to gain support from the sides or base of the tank or vessel. It is essential that the removable cover of the tank be designed in such a way that there is a watertight connection

34、between the cover and the open top of the chamber/manhole shaft or base, and that there is an opening big enough for visual inspection inside the chamber or manhole. The temperature of the water applied shall be (20 2) C or as otherwise specified in the product standard. 5.4 End closures, to seal an

35、y open pipe socket(s), spigot(s) and additionally, the riser shaft. When testing for structural integrity (20 C), the end closures shall be created using standard pipes with end caps. If testing for durability at higher temperatures, plates welded to the end of the sockets or spigots may used to sea

36、l the pipe connections. 5.5 Pressure or vacuum source, capable of applying and maintaining the test pressure specified in the product standard specification for the inspection chamber or manhole base as being the maximum pressure that the inspection chamber or manhole base shall be able to withstand

37、 (subject to a minimum of 0,02 MPa). 5.6 Pressure measuring devices, capable of measuring the internal negative or external water test pressure to within an accuracy of 2 %. 5.7 Thermometer, capable of measuring the temperature of the medium surrounding the test assembly to an accuracy of 0,5 C. BS

38、ISO 13267:2010ISO 13267:2010(E) ISO 2010 All rights reserved 35.8 Deflection measuring equipment (optional), capable of measuring the deflection of the main channel to within an accuracy of 0,1 mm. (If required by the product standard.) 5.9 Test assembly, comprising the base and a portion of the ris

39、er, if required, to ensure a height of at least 300 mm above the top of the main channel. Unless otherwise specified in the product standard, one test assembly shall be prepared for each test carried out. NOTE The preferred configuration for testing the inspection chamber/manhole base is the straigh

40、t through configuration without side entries. 6 Conditioning Unless otherwise specified in the product standard, the test piece shall be tested no less than 21 days after manufacture and after conditioning in air for at least 6 h at a temperature of between 15 C and 25 C. 7 Test environment Unless o

41、therwise specified in the product standard, testing shall be carried out at a temperature of between 15 C and 25 C. 8 Procedure 8.1 Internal negative pressure testing using a free standing test assembly 8.1.1 Seal all inlets and outlets of the test assembly and the top of the riser shaft using the e

42、nd closures. NOTE 1 Internal or external tie bars can be used between the inlet and outlet closures to avoid the transmission of external end loading forces to the inspection chamber/manhole base via the end closures. NOTE 2 The test assembly can be turned 180 upside down to simplify the test. If th

43、e base is designed with a double wall, where the outer wall is designed to withstand upthrust, one or more 3 mm to 4 mm diameter holes shall be drilled through the inner wall to ensure that the internal negative pressure is loaded against the outside wall of the base assembly. 8.1.2 If the measureme

44、nt of deflection is required by the product standard install the two devices for measuring deflection at points W and H, as shown in Figures 1 and 2. In the case where bases are non-spherical, the relative vertical deformation of the base can be measured directly from a datum provided by a stiff bea

45、m connected at points HLand HR. If a separate datum is used, the points HL, HRand HMshall be measured from that datum during the test and the final deflection, expressed as YV, which is given by Equation (1): YV= (HL+ HR)/2 HM(1) The change of the width of the main channel shall be expressed as YH,

46、where this is the change to dimension W. The sample shall be visibly inspected for evidence of cracks after completion of the test.
