Scope

1.1 This Standard applies to line pressure regulators (see Clause 3, Definitions), constructed entirely of new, unused parts and materials, hereinafter referred to as regulator(s), either individual or in combination with overpressure protection devices, hereinafter referred to as device(s), intended for application in gas piping systems between the service regulator, or LP-gas 2 psi (13.8 kPa) service regulator, and the gas utilization equipment.

1.2 This Standard applies to regulators for operation with natural, manufactured and mixed gases, liquefied petroleum gases, and LP gas-air mixtures.

1.3 This Standard applies to regulators classified in accordance with their intended application with reference to inlet and outlet pressures.

1.4 The tests specified herein are conducted at a room temperature of 77 ± 10 °F (25 ± 5.5 °C). Regulators and vent limiters complying with the provisions of this Standard are considered as having an operating temperature range of 32 °F (0 °C) to 125 °F (51.5 °C). At the option of the manufacturer, a greater operating temperature range may be specified, in which case additional tests as outlined in Clause 5.4, Leakage, and Clause 5.10, Continued operation, will be conducted.

1.5 If a value for measurement as given in this Standard is followed by an equivalent value in other units, the first stated value is to be regarded as the specification.

1.6 All references to psi throughout this Standard are to be considered gauge pressures unless otherwise specified.

1.7 Clause 2, Reference publications, contains a list of standards specifically referenced in this Standard.

1.8 Clause 8, Items unique to Canada, contains provisions that are unique to Canada.

1.9 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 designed normative (mandatory) or informative (non-mandatory) to define their application.
