General

This Standard covers mechanical water flow shut off devices that are designed to shut off the cold water supply to water heater or the water supply to water closets, shower head, sink or bathtub upon actuation and specifies requirements for materials, physical characteristics, performance testing, and markings.

This standard applies to mechanical automatic water supply shutoff devices and component(s) (see Part IV, Definitions), hereinafter referred to as systems and component(s) constructed entirely of new, unused parts and materials, which is intended for use with water heaters, bathtubs, shower heads, lavatories, sinks, or water closets.

This standard does not cover shut off device installed on water heaters that shall be connected to the thermocouple or gas line within the system.

Alternative Materials

The requirements of this Standard are not intended to prevent the use of alternative materials or methods of construction provided such alternatives meet the intent and requirements of this Standard.

Terminology

In this Standard,

(a) "shall" is used to express a requirement, i.e., a provision that the user is obliged to satisfy to comply with the Standard;

(b) "should" is used to express a recommendation, but not a requirement;

(c) "may" is used to express an option or something permissible within the scope of the Standard; and

(d) "can" is used to express a possibility or a capability.

Notes accompanying sections of the Standard do not specify requirements or alternative requirements; their purpose is to separate explanatory or informative material from the text. Notes to tables and figures are considered part of the table or figure and can be written as requirements.

Units of Measurement

SI units are the primary units of record in global commerce. In this Standard, the inch/pound units are shown in parentheses. The values stated in each measurement system are equivalent in application, but each unit system is to be used independently. All references to gallons are to U.S. gallons.
