Specifies the requirements of precast concrete access chambers (PCAC), and the minimum requirements for the materials to be used in, and the manufacture of, controlled quality PCAC components and includes descriptions of methods of sampling and testing of components. The Standard applies to PCAC components manufactured from reinforced or unreinforced concrete that are intended for use with buried sewer pipes to a depth of 6 m and for pipes not greater than 300 mm in diameter. While the Standard is limited to sewerage applications, reference may be made for drainage applications. Recommended installation procedures are not covered by this Standard.

This Standard describes the requirements of precast concrete access chambers and the minimum requirements for the materials to be used in, and the manufacture of, controlled quality precast concrete access chamber (PCAC) components. It also describes methods of sampling and testing of components manufactured in accordance with this Standard.This Standard applies to precast concrete access chamber components manufactured from steel reinforced or unreinforced concrete that are intended for use with buried sewerage systems to a depth of 6 m and for sewer pipes not greater than 300 mm diameter.NOTES:1 Advisory information on means for demonstrating compliance with this Standard is given in Appendix A.2 Guidance on the information to be supplied between purchaser and supplier at the time of enquiry or order is given in Appendix B.3 For sewer pipes greater than 300 mm diameter and shafts deeper than 6 m, agreement may be made between the manufacturer/regulatory authority/purchaser.
