The International Association of Plumbing and Mechanical Officials (IAPMO) has published IAPMO/ANSI/CAN Z1117: Press Connections, and IAPMO/ANSI/CAN Z124.10: Water Closets and Urinal Partitions, as American National Standards (ANS) and National Standards of Canada (NSC).

A copy of IAPMO/ANSI/CAN Z1117 can be purchased here. A copy of IAPMO/ANSI/CAN Z124.10 can be purchased here.

The IAPMO/ANSI/CAN Z1117 standard covers press connections made with the following:

• Copper or copper alloy fittings and Type K, L, and M copper tube
• Carbon steel fittings and Schedule 10 and 40 carbon steel pipe
• Stainless steel fittings and Schedule 5, 10, and 40 stainless steel pipe
• Stainless steel fittings and stainless steel pipe complying with the specific dimensions

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. 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 IAPMO/ANSI/CAN Z124.10 standard covers urinal and water closet partitions and specifies requirements for materials, construction, performance testing, and markings. This standard fills a gap in the industry that has existed for many years. IAPMO/ANSI/CAN Z124.10 brings a comprehensive approach in addressing the essential requirements for materials, strength, and durability and design specification to properly address partitions for water closets and urinals. With the expanded use of all-gender toilet facilities, IAPMO Z124.10 is an extremely important new standard for specifying the level of privacy and security for the users of water closets.

Both of these standards were developed by a balanced consensus body that consists of professionals in both the United States and Canada. Both of these standards are available in English and French. Visit IAPMO’s standards website for more information: iapmo.org/standards-development.
