12、pment. The first organizational meetingwas held on July 22, 1958. At the meeting on May 1, 1964, Panel No. 21 was created to establishstandards for roof drains, floor drains, backwater valves, and other drainage specialties. Its scopewas as follows: The recommendation of suitable existing standards
13、in cooperation with interestedsponsors, 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 A112 Committee, undergoing a number of organizational changes over the years, is cur-rently identified as ASME A1
14、12 Standards Committee. A112 Panel 21 Working Groups, with theresponsibility for drainage products were reorganized as Project Teams with sanitary floor sinksassigned to Project Team 6.7. The project team met twice for the purpose of developing thisStandard, including criteria from the International
15、 Association of Plumbing and MechanicalOfficials (IAPMO) product standards PS-62, PS-83, and PS-84.Suggestions for improvement of this Standard are welcome. They should be sent to TheAmerican Society of Mechanical Engineers, Attn: Secretary, A112 Standards Committee, ThreePark Avenue, New York, NY 1
