AS 4198:1994 PDF Download

AS 4198:1994 is a standard that provides requirements for precast concrete access chambers used in sewerage applications. It specifies the minimum material requirements and manufacturing standards for these access chambers, ensuring controlled quality. The standard also outlines the sampling and testing methods for components manufactured in adherence to the standard.

This standard specifically applies to precast concrete access chamber components made from steel-reinforced or unreinforced concrete. It is intended for use with buried sewerage systems up to a depth of 6 meters and with sewer pipes that have a maximum diameter of 300 mm. The standard provides guidance on means for demonstrating compliance and offers information on the details to be exchanged between the purchaser and the supplier during the enquiry or order process.

It is worth noting that for sewer pipes larger than 300 mm in diameter or shafts deeper than 6 meters, alternative agreements can be reached between the manufacturer, regulatory authority, and purchaser. Appendices A and B of the standard provide advisory information and guidance on compliance demonstration and communications respectively.
