This Standard specifies minimum requirements for pipes and fittings manufactured from fibre-reinforced concrete using standard curing, including autoclaving, for the conveyance of gravity water supply, and stormwater, waste water and sewage drainage. Four classes of pipes are covered by this Standard, distinguished on the basis of long-term design load: Class 1, Class 2, Class 3, and Class 4. Other classes of pipe may be designed using the principles described in this Standard. This Standard addresses the effect of creep under load by either, regression analysis of pipe materials (see Appendix H), or long-term stiffness prediction. NOTES: 1 Fibre-reinforced concrete pipe is herein referred to as 'pipe'. 2 The load classes correspond with those of AS 4058. 3 This Standard does not cover the assessment of external service loads to which a pipe will be subjected to in a particular installation. Purchasers should, therefore, satisfy themselves that the class of pipe specified or selected on the basis of this Standard is suitable for its intended application. For buried pipes, reference to AS 3725 is required. 4 Guidance on the information to be supplied by the purchaser at the time of enquiry or order is given in Appendix A. 5 Appendix B provides concentration limits for commonly occurring soil/terrain constituents of the buried environment, but does not provide special requirements for pipes intended for use in environments aggressive to concrete. Where such applications are envisaged, the advice of the manufacturer should be sought.
