Conclusion

Samples of DN300, DN400, DN450 and DN630 recycled PE pipe supplied by Recycled Plastic Pipe Manufactures Pty. Ltd. were tested for pipe Stiffness in accordance with AS/NZS 1462:22:1997 and given a stiffness rating in accordance with AS/NZS 1260:2002 and AS/NZS 1254:2002. Pipe sizes DN400, DN450 and DN630 were found to meet the requirements of SN4 according to both AS/NZS 1260:2002 and AS/NZS 1254:2002. The DN300 pipe sample was found to meet the requirements of SN6 and SN4 rating in.
