ASME A112.4.14-2017 pdf download.Manually operated valves for use in plumbing systems.
1 Scope 1.1 This Standard specifies requirements for manually operated valves, also known as supply line stops, in sizes NPS 4 and smaller. 1.2 Valves covered by this Standard are intended for a) installation as water shutoff valves between the meter and the supply stop; and b) service at temperatures between 5 °C (40 °F) and 71 °C (160 °F), with an allowable working pressure rating not less than 862 kPa (125 psi). 1.3 This Standard does not apply to hose end valves or endpoint devices as defined in Section 9 of NSF/ ANSI 61. 1.4 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 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 U.S. gallons. For information on the conversion criteria used in this Standard, see Annex A.
