This standard provides the minimum requirements for full-encirclement-type band repair clamps and full-encirclement service connection clamps for various pipe materials, including system components, testing, and marking requirements.

This standard describes fabricated full-encirclement stainless-steel band clamps for use in the repair or tapped service connection of potable water, wastewater, and reclaimed water piping systems. They are intended for nominal pipe sizes 2 in. (50 mm) through 12 in. (300 mm). Full-encirclement repair clamps shall be manufactured completely from stainless-steel or a combination of stainless-steel band and cast ductile-iron lug, along with stainless or low-alloy carbon steel bolts and nuts, depending on service requirements and the purchaser's documents. Tapped service connection outlets may be provided and shall range from 1/2 in. through 3 in. (12 mm through 75 mm) sizes., with either NPTor AWWA-type threaded connections. This standard does not cover stainless-steel tapping saddles whose seal is not fully circumferential. Repair clamps for larger than 12-in. (300-mm) nominal pipe diameters pipe are available from various manufacturers but are not covered by this standard.
