2622-126 (1999)

1 PURPOSE This standard specifies the physical and dimensional characteristics of prefabricated reinforced concrete and unreinforced concrete pipes and monolithic lateral connections. This standard also specifies control and test methods to verify these requirements. 2 SCOPE This standard applies to round sections of reinforced concrete and unreinforced concrete pipes intended for burial underground and conveying domestic wastewater or storm water by gravity flow. This standard applies to reinforced concrete pipes and monolithic lateral connections of diameters between 200 mm and 3600 mm and to unreinforced concrete pipes and monolithic lateral connections of diameters between 150 mm and 900 mm. NOTES ? 1 For requirements concerning installation of concrete wastewater pipes, refer to Standard NQ 1809-300. 2 In some circumstances, wastewater may contain substances such that pipes are subject to special conditions of exposure. The pipe designer shall consider such circumstances. 3 Domestic wastewater pipes and storm water pipes are subject to special leak tightness requirements as defined in Chapter 7 of this standard.
