Specifies thread form, thread dimensions, tolerance, and associated gauges and gauging practices for fastening threads for pipes of nominal bore 4mm to 150mm. Incorporates modified tables for screw gauge limits and dimensions for fastening pipe threads; setting plugs for GO and NOT GO screw calliper gauges; provision for the use of adjustable screw calliper gauges; and wear allowance for GO gauges.

This Standard specifies thread form, thread dimensions, tolerance, and associated gauges and gauging practices for threads used for fastening pipes.The Standard covers pipe threads for pipe of nominal bore size 4 mm to 150 mm.NOTES:1 Where these threads are used on pipes for conveying fluids, the sealing is effected by means other than thread interference (e.g. gaskets on flanges or O-rings).2 Pipe threads of Whitworth form where pressure tight joints are made on the threads are specified in AS 1722.1.
