This is the first edition of ASSE 1002/ASME A112.1002/CSA B125.12, Anti-siphon fill valves for water closet tanks. It supersedes the previous edition of ASSE 1002, published in 2008, and it replaces the requirements for anti-siphon fill valves in CSA B125.3, Plumbing fittings, published in 2012.
1.1 This Standard covers anti-siphon fill valves intended to be installed in water closet tanks. Note: In this Standard, anti-siphon fill valves are also referred to as "devices". 1.2 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 SI units are the units of record in Canada. In this Standard the inch/pound units are shown in parentheses. The values stated in each measurement system are equivalent in application; however, each system is to be used independently. Combining values from the two measurement systems can result in non-conformance with this Standard. All references to gallons are to U.S. gallons.
