AS 1074 (NZS 1074)ndi chitoliro chachitsulo ndi zolumikizira za ku Australia (New Zealand).
Izi zimagwira ntchito pa mapaipi achitsulo opangidwa ndi ulusi ndi zolumikizira zomwe zafotokozedwa mu AS 1722.1, ndi mapaipi achitsulo okhala ndi mbali yosalala kuyambira DN 8 mpaka DN 150.
Makoma atatu a chitoliro chachitsulo amatchulidwanso, opepuka, apakatikati, ndi olemera.
Machubu a AS 1074 akhoza kupangidwa ndi aliyensewopanda msokokapena njira zolukidwa, ndipo njira yolukidwa nthawi zambiri imakhalaERW.
Mitundu itatu ya malekezero a mapaipi akuphatikizidwa: wamba, wopindika, ndi wopindika.

Mphamvu yocheperako yopezera mphamvu: 195 MPa;
Mphamvu yocheperako yokoka: 320 - 460 MPa;
Kutalika: osachepera 20%.
Chitoliro chilichonse chachitsulo chiyenera kuyesedwa posankha imodzi mwa njira zoyesera kulimba kwa chitoliro chachitsulo.
Mayeso a Hydrostatic
Chitoliro chachitsulo chimasunga mphamvu ya madzi ya 5 MPa kwa nthawi yayitali yokwanira popanda kutuluka.
Mayeso Osawononga
Mayeso a Eddy omwe alipo pano akugwirizana ndi AS 1074 Appendix B.
Kuyesa kwa Ultrasound motsatira AS 1074 Appendix C.
Makulidwe a khoma: opepuka, apakatikati, komanso olemera.
