ASME A112.18.1-2005 pdf download.Plumbing supply fittings.
This is the first edition of ASME A1 1 2.1 8.1 /CSA B1 25.1 , Plumbing supply fittings. This joint Standard was developed in response to an industry request for a Standard for testing plumbing supply fittings that would be acceptable in both Canada and the United States. Its coverage is restricted to devices located between the supply line stop and the terminal fitting. Plumbing waste fittings are covered by ASME A1 1 2.1 8.2/CSA B1 25.2, Plumbing waste fittings. Devices not covered by this Standard or by ASME A1 1 2.1 8.2/CSA B1 25.2, e.g., temperature-actuated in-line mixing valves and flexible connectors under continuous pressure, are covered by CSA B1 25.3, Plumbing fittings. The technical content of Clause 5.1 0 of this Standard was developed jointly by the American Association of Sanitary Engineering (ASSE) and CSA. This Standard replaces ASME A1 1 2.1 8.1 -2003, Plumbing Fixture Fittings, and, together with ASME A1 1 2.1 8.2/CSA B1 25.2 and CSA B1 25.3, replaces CAN/CSA-B1 25-01 , Plumbing Fittings. The concept of harmonization for plumbing fittings arose in the early 1 990s, when a free trade agreement between Canada, Mexico, and the United States began to be discussed. Standards development organizations (SDOs) were at the forefront of these discussions and an opportunity soon arose for those SDOs involved in setting requirements for plumbing products to establish a process for harmonization. However, the effort to develop a trinational Standard stalled until 2001 , when ASME and CSA decided to develop a binational Standard for plumbing fixture fittings. Harmonization activities were undertaken by a Joint Harmonization Task Group (JHTG), in which the ASME and CSA plumbing fitting committees were equally represented. The responsibility for procedural matters and final approval of technical content was assumed by committees and teams at higher levels within each SDO.
(2) ASME does not “approve,” “rate,” or “endorse” any item, construction, proprietary device, or activity. (3) ASME does not take any position with respect to the validity of any patent rights asserted in connection with any items mentioned in this document, and does not undertake to insure anyone utilizing a standard against liability for infringement of any applicable letters patent, nor assume any such liability. Users of a standard are expressly advised that determination of the validity of any such patent rights, and the risk of infringement of such rights, is entirely their own responsibility. (4) Participation by federal agency representative(s) or person(s) affiliated with industry is not to be interpreted as government or industry endorsement of this standard. (5) ASME accepts responsibility for only those interpretations of this document issued in accordance with the established ASME procedures and policies, which precludes the issuance of interpretations by individuals. (6) ASME issues written replies to inquiries concerning interpretation of technical aspects of this Standard. All inquiries regarding this Standard, including requests for interpretations, should be addressed to: Secretary, A112 Standards Committee The American Society of Mechanical Engineers Three Park Avenue New York, NY 10016-5990 A request for interpretation should be clear and unambiguous. The request should • cite the applicable edition of the Standard for which the interpretation is being requested. • phrase the question as a request for an interpretation of a specific requirement suitable for general understanding and use, not as a request for an approval of a proprietary design or situation. The inquirer may also include any plans or drawings, which are necessary to explain the question; however, they should not contain proprietary names or information. ASME procedures provide for reconsideration of any interpretation when or if additional information that might affect an interpretation is available.
