26、2.1 PVC pipes and fittings PVC pipes and fittings installed in accordance with this Standard shall comply with the relevant Standard given in Clause 1.1. In Australia, for plumbing and drainage applications, PVC pipes and fittings shall be authorized in accordance with plumbing industry regulations.
27、 In New Zealand, for plumbing and drainage applications, PVC pipelines shall meet the requirements of AS/NZS 3500. Pipes and fittings manufactured in accordance with AS 1273 shall not be installed for stormwater stack heights exceeding 15 m and shall not be encased in concrete for multi- storey work
28、. 2.2.2 Chemical resistance Where the application is for the conveyance of chemicals, information on the suitability of PVC pipe for that application may be found in ISO TR 10358 or obtained from manufacturers. For installations in contaminated ground the suitability of PVC for that service shall be
29、 determined. Such contamination may take the form of actual attack on the material, affecting the systems structural integrity, or it may permeate the pipe or fitting, not adversely affecting structural strength but potentially tainting pipe contents. Such permeation might not be an issue for pipes
30、that do not convey drinking water. In drainage applications, the tables of chemical resistance may need to be varied to take account of the concentration of the chemicals and the duration of contact (e.g., a laboratory drainage system). For pipes joined with elastomeric seals or solvent cement joint
31、s, consideration shall be given to the chemical resistance of the seals or the solvent cement. NOTE: Further guidance on chemical resistance is available from the relevant sources listed in Appendix A. Alternatively, refer to the pipe manufacturer. It may be necessary to assess the effects of extern
32、al chemical contamination. 2.2.3 Permeation For PVC, as with other materials, including those used for jointing, permeation depends upon the concentration of the contaminant and its nature. Permeation is an extremely slow process and significant levels will occur only under conditions of prolonged c
33、ontact at high levels of concentration. In general, PVC is highly resistant to permeation by petroleum products, alcohols (ethanol), aliphatic hydrocarbons and organic acids. In instances involving significant levels of contamination, expert advice should be sought. Accessed by UNIVERSITY OF SOUTH A
34、USTRALIA on 15 Aug 2008 9 AS/NZS 2032:2006 COPYRIGHT 2.2.4 Buckling under external load and vacuum PVC pipes and fittings installed below the water table are subjected to an external load and may buckle, especially in a deep installation. The pipe class selected in the installation shall be high eno
35、ugh to ensure stability against buckling failure when subjected to the maximum external hydrostatic pressure possible for the deepest pipe in the installation. When grouting is undertaken, the grouting pressures should be determined to ensure that empty pipes do not deflect or buckle beyond acceptab
36、le criteria as a result of grout pressure. Where the contribution of grouting pressure to buckling forces on an empty pipe is uncertain, grouting should be carried out with the pipe internally pressurized. 2.2.5 Fittings Fittings used in conjunction with PVC pipe shall meet the performance requireme
37、nts of the relevant Australian, New Zealand, International or industry Standard and be capable of withstanding the proposed service conditions for the design life of the installation. In Australia, for plumbing and drainage applications, fittings made of materials other than PVC shall be authorized
38、in accordance with plumbing industry regulations. 2.2.6 Solvent cements and priming fluids Solvent cements and priming fluids for PVC-U and PVC-M pipelines shall comply with AS/NZS 3879 except where a gap-filling solvent cement is required. For PVC-C pipelines, solvent cement and priming fluids shal
39、l comply with ASTM F493. 2.2.7 Elastomeric seals Elastomeric seals shall comply with the applicable Parts of the AS 1646 series of Standards and shall be in accordance with the recommendations of the manufacturer of the socketed pipe or fitting. For drinking water applications, elastomeric seals sha
40、ll comply with AS/NZS 4020. 2.2.8 Lubricants for elastomeric seals and expansion joints Lubricants used in conjunction with elastomeric seals shall be those specified by the manufacturer of the socketed pipe or fitting. For drinking water applications, lubricants shall also comply with AS/NZS 4020.
41、2.3 HANGER AND CLIPS Hangers and clips shall be corrosion-resistant for the intended environment. Sliding joints, pipe hangers and clips shall be constructed so that, when fully tightened, longitudinal movement of the pipe is possible without damage to the pipe or fitting. Anchor clips for fixed poi
42、nts shall be constructed so that, when fully tightened, the fitting or pipe is securely and evenly clamped to prevent movement. Care shall be taken to ensure that pipes and fittings are not distorted by over-tightening. 2.4 PIPE EMBEDMENT AND TRENCH-FILL MATERIALS Embedment and trench-fill materials
43、 shall comply with the AS/NZS 3500 series or AS/NZS 2566.2 or specific industry standards, as required. 2.5 TOOLS AND EQUIPMENT Specialized tools and equipment used in the installation, repair, testing and commissioning of PVC pipes and fittings shall be as recommended by the pipe and fittings manuf
44、acturers.

45、 inspection. 3.2 TRANSPORT, HANDLING AND STORAGE 3.2.1 General PVC pipes and fittings shall be transported, handled and stored with care by the installer at all times to avoid physical damage (e.g., gouging, scoring, scratching, localized deformation, ovalization or impact damage) that could adverse
46、ly affect performance. 3.2.2 Transportation When being transported, pipe shall be supported in a secure manner to prevent damage, excessive distortion of the pipe cross-section or bowing or twisting of the pipe. 3.2.3 Storage The storage area provided for pipe shall (a) be a flat surface free of any
47、 sharp stone or projection, which may cause damage or localized deformation to the pipe; and (b) be suitable for the use of the proposed loading and unloading of equipment without the risk of accidental damage to the pipe. If the total period of exposed storage outdoors is likely to exceed 12 months
48、, pipes and fittings shall be covered and stored in a manner that allows ventilation and prevents heat entrapment. Pipes and fittings may be stored in this manner indefinitely. Stacking of pipes during storage shall be in accordance with the manufacturers recommendations. Similar provisions apply to
49、 fittings, except those fittings marked with specific storage instructions. NOTE: Storage outdoors may be extended by covering pipes and fittings with an appropriate material such as hessian or white PE sheet. Black plastic sheeting may cause unacceptable heat build-up and should not be used. Joint lubricants shall be stored in sealed containers until ready for use. Solvent cements and priming fluids shall be kept in sealed containers and stored away from direct heat sources. Solvent cements shall be used before the use
