IAPMO Updates Standard on Press Fittings
By HPAC MagazineHealth & Safety HPAC General Plumbing IAPMO press fittings standards
The new IAPMO/ANSI/CAN Z1117 supersedes the IAPMO PS 117 standard references in model plumbing codes.
The International Association of Plumbing and Mechanical Officials (IAPMO) has published IAPMO/ANSI/CAN Z1117, Press Connections as American National Standards (ANS) and National Standards of Canada (NSC).
The new IAPMO/ANSI/CAN Z1117 supersedes the widely used IAPMO PS 117, which is a standard referenced in the model plumbing codes including the ANSI-accredited Uniform Plumbing Code (UPC). It specifies requirements for materials, physical characteristics, performance testing and markings.
The IAPMO/ANSI/CAN Z1117 standard covers press connections made with:
(a) copper or copper alloy fittings and Type K, L, and M copper tube;
(b) carbon steel fittings and Schedule 10 and 40 carbon steel pipe;
(c) stainless steel fittings and Schedule 5, 10, and 40 stainless steel pipe; or
(d) stainless steel fittings and stainless-steel pipe complying with the specific dimensions in Table 1.
Products covered by this standard include fittings, tube and pipe with press connection ends combined with other types of connections (e.g., threaded, soldered, and push‐fit).
The international association has also published IAPMO/ANSI/CAN Z124.10, Water Closets and Urinal Partitions, a standard that covers urinal and water closet partitions and specifies requirements for materials, construction, performance testing and markings.
The association notes that with the expanded use of all-gender toilet facilities, the IAPMO Z124.10 is an important new standard for specifying the level of privacy and security for the users of water closets.
Both standards were developed by professionals in both the U.S. and Canada, and both standards are available in English and French.
