The results of their activity resulted in their Interim Guide Criteria IGC 203-2004, which was used as a benchmark for perance of such devices, which are now known as “Sanitary Waste Valves.” IGC 203-2004 was ted to the ASME Standards Committee A112, Plumbing Materials and Equipment, for conversion into an American National Standard. A112 Project Team 18.8 was established for the purpose of undertaking this task. The purpose of this Standard is to establish a generally acceptable standard for sanitary waste valves for installation on tubing. Its purpose is to serve as a guide for producers, distributors, architects, engineers, contractors, installers, inspectors, and users; to promote understanding regarding materials, manufacture, and installation; and to provide for identifying fittings for installation on the valve complying with this Standard. Sanitary waste valves are intended for use as an alternative to tubular p-traps. Sanitary waste valves provide a waterless barrier between the waste system and the fixture. Suggestions for improvement of this Standard will be welcomed. They should be sent to The American Society of Mechanical Engineers, Attn Secretary, A112 Standards Committee, Three Park Avenue, New York, NY 10016-5990. This Standard was approved by the American National Standards Institute on June 2, 2009. iv Copyright ASME International Provided by IHS under license with ASME LicenseeHong Kong Polytechnic Univ/9976803100 Not for Resale, 10/19/2009 034101 MDTNo reproduction or networking permitted without license from IHS --,,,,,,,,,,,,--,,,,,,,--- w w w . b z f x w . c o m ASME A112 COMMITTEE Standardization of Plumbing Materials and Equipment The following is the roster of the Committee at the time of approval of this Standard.

ThisStandarddoesnotdefinetherequirementsforprod- ucts to be used in urinals or water closets. It is not intended that products meeting this Standard will be used in a urinal or water closet. The provisions of this Standard are not intended to prevent the use of any alternate material or of construction provided any such alternate meets the intent of this Standard. 1.2 Units of Measurement Values are stated in U.S. Customary units and in the International System of Units SI. The U.S. Customary units shall be considered as the standard. In this Standard, gallons U.S. liquid per minute is abbreviated gpm and liters metric liquid per minute is abbreviated L/min. 1.3 References The following documents a part of this Standard to the extent specified herein.
