Preface
This is the first edition of ASME A112.6.8/CSA B79.8, Trench drains. It supersedes CSA B79, Commercial and residential drains and cleanouts standard, published in 2008, and the testing and certification requirements for trench drains of the ASME A112.6.3-2019, Floor and Trench Drains Standard. This Standard was prepared by the ASME/CSA Harmonization Task Group on Drains under the jurisdiction of the ASME A112 Standards Committee on Plumbing Materials and Equipment and the CSA Technical Committee on Drains and Interceptors. The ASME A112 Standards Committee operates under the jurisdiction of the ASME Board on Standardization and Testing and the CSA Technical Committee operates under the jurisdiction of the CSA Strategic Steering Committee on Construction and Civil Infrastructure. This Standard is considered suitable for use for conformity assessment within the stated scope of the Standard. This Standard was approved as an American National Standard by the American National Standards Institute on May 9, 2022. This Standard has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group.
Scope
1.1 Inclusions This Standard specifies design and performance requirements for trench drains, utility channels, and grate systems that are used inside of, or adjacent to, building structures that are typically non-residential. Note: These channels are not typically subject to high-speed vehicles but can be subjected to concentrated heavy loads such as hard-wheeled forklifts.
1.2 Linear shower drains Drains with outlet size NPS-2 and smaller, intended only for installation in shower areas, are covered in ASME A112.18.2/CSA B125.2 and can also be covered in this Standard.
1.3 Illustrations Figures 1 through 7 illustrate typical trench and slot drains and are not intended to restrict design or to specify requirements.
1.4 Terminology In this Standard, “shall” is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the standard; “should” is used to express a recommendation or that which is advised but not required; and “may” is used to express an option or that which is permissible within the limits of the Standard. Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material. Notes to tables and figures are considered part of the table or figure and may be written as requirements. Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application.
1.5 Units of measure The values given in either SI (metric) or U.S. Customary units of measure are equivalent in application; however, each measurement system is to be used independently of the other. In this Standard, U.S. Customary units are shown in parentheses. Combining values from the two measurement systems can result in non-conformance with this Standard.
1.6 Alternatives The requirements of this Standard are not intended to prevent the use of alternative designs, materials, or methods of construction, provided such alternatives meet the intent and requirements of this Standard.
