Draft Scope/Description:

1 Scope

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.

1.1 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.

1.2 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.

1.3 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.

1.4 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.
