The International Association of Plumbing and Mechanical Officials (IAPMO<sup>®</sup>) has published ANSI/CAN/IAPMO Z1001, Prefabricated Gravity Grease Interceptors, as an American National Standard (ANS) and National Standard of Canada (NSC). The binational standard is available in both English and French.
First published in 2007, this is the fourth edition of IAPMO Z1001 and the first to be published as an ANS and NSC. This standard supersedes the previous editions, last published in 2016. This is the first edition of this standard with both American and Canadian designation.
The ANSI/CAN/IAPMO Z1001 standard covers prefabricated gravity grease interceptors made of concrete, fiber‐reinforced polyester (FRP), thermoplastic, or steel, and specifies requirements for design, materials, performance, testing and markings.
A copy of ANSI/CAN/IAPMO Z1001-2021 may be purchased through the IAPMO Online Store in English
or French.
For more than 30 years, IAPMO has developed plumbing product standards as American National Standards, initially as the secretariat for the ANSI Z124 Technical Committee in 1984, and since 2005 independently under its own American National Standards Institute (ANSI)-accredited standards development procedures. In 2018, IAPMO received accreditation through the Standards Council of Canada (SCC) for development of National Standards of Canada, thus accepting the responsibility for development of CAN/IAPMO-designated standards.
