ASME A112.18.2-2005 pdf download.Plumbing waste fittings.
1 Scope 1.1 This Standard covers plumbing waste fittings of sizes NPS-2 and smaller. 1.2 Plumbing supply fittings are covered by ASME A1 1 2.1 8.1 /CSA B1 25.1 . 1.3 Other devices, e.g., temperature-actuated in-line mixing valves and flexible connectors under continuous pressure, are covered by CSA B1 25.3 or other plumbing product Standards. 1.4 This Standard does not apply to pipes and tubes or pipe and tube fittings. 1.5 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. 1.6 The values stated in either SI (metric) or yard/pound units are to be regarded as the standard. SI units are the units of record in Canada. In this Standard, the yard/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 US gallons.

Continuous waste — a drain connection for multiple compartments of a fixture or fixtures connected to a common trap or for connecting other fixtures to a common trap. Diversion tee — a component of a continuous waste assembly consisting of a tee fitting and an integral element that directs the flow downward to the outlet of the tee. Fixture waste fitting — any part of a waste system from a plumbing fixture to, and including, a fixture trap outlet or trap wall adapter. Patent overflow — a lavatory waste fitting incorporating an overflow opening. Significant surface — an exposed surface that, if blemished, spoils the appearance or affects the performance of a fitting. Slip joint — an adjustable tubing connection that consists of a compression nut and compression washer and is designed to fit a threaded adapter fitting or a standard taper pipe thread. Strainer — a device designed to prevent debris from entering a drainage system. Strainer basket — a removable component of a sink strainer assembly, designed to collect debris. Strainer body — the fixed, exposed component of a sink strainer assembly connected to the fixture that accommodates the strainer basket. Strainer shell — the unexposed component of a sink strainer assembly that connects the strainer body to the fixture that accommodates the strainer basket.
