scope:

The American National Standards Committee A112 was organized on July 27, 1955 for the purpose of standardization of plumbing materials and equipment. The first organizational meeting was held on July 22, 1958. At the meeting on May 1, 1964, Panel No. 21 was created to establish standards for roof drains, floor drains, backwater valves and other drainage specialties. Its scope was as follows: The recommendation of suitable existing standards in cooperation with interested sponsors, or the development of adequate new standards as needed for roof drains, floor drains, and other drains as used or installed in plumbing systems.

The A 112 Committee undergoing a number of organizational changes over the years is currently identified as ASME Standards Committee A 112. A112 Panel 21 Working Groups with the responsibility for drainage products were reorganized as Project Teams with sanitary floor sinks assigned to Project Team 6.7. The project team met twice for the purpose of developing this Standard including criteria from the International Association of Plumbing and Mechanical Officials (IAMPO) product standards PS-62, PS-83, and PS-84.

Suggestions for improvement of this Standard will be welcomed. They should be sent to The American Society of Mechanical Engineers; Attn.: Secretary, A112 Committee; Three Park Avenue; New York, NY 10016-5990.

This Standard was approved as an American National Standard on January 17, 2001.
