scope:

This standard pertains to the various classes and types of stainless-steel fittings that are intended for use in facilities of water distribution systems.

Classes. This standard covers three classes of materials; wrought austenitic stainless-steel fittings; cast austenitic stainless-steel fittings; and welded or weld-fabricated austenitic stainless-steel fittings, in diameters ranging from ½ in. (13 mm) to 72 in. (1,800 mm).

Large fittings. Fittings larger than 72 in. (1,800 mm) in diameter may be manufactured with special consideration given to the specific nature of the application.

Appurtenances not covered by this standard. Mechanical grooved-end fittings, compression fittings, grooved-end couplings, tapping sleeves, sleeve-type couplings and split-sleeve couplings are covered by other ANSI/AWWA standards.

Purpose

The purpose of this standard is to provide purchasers, manufacturers, and constructors with the minimum requirements for stainless-steel fittings, including testing, inspection, and marking requirements.
