Preface

This is the second edition of ANSI Z21.90 / CSA 6.24, Standard for Gas Convenience Outlets and Optional Enclosures. It supersedes the previous edition published in 2001.

Scope

1.1
This Standard applies to gas convenience outlets (see Clause 3, Definitions), hereinafter referred to as gas outlets and optional enclosures, not to exceed 1-1/2 in (38.1 mm) and pressures not to exceed 5 psi (34.5 kPa), capable of operation at temperatures between 32°F and 200°F (0°C and 93.3°C) if intended for indoor use only, or between -20°F and 200°F (-28.8°C and 93.3°C) if intended for indoor/outdoor use. Indoor/outdoor use is also to be capable of operation at -40°F (-40°C) when so specified by the manufacturer.

1.2
This Standard set forth the minimum capabilities, characteristics, and properties that a gas outlet and optional enclosure must possess, at the time of manufacture, in order to be considered suitable for use in a gas piping system. Details of design and manufacture not stated in these requirements, including such design and production tests that will produce gas outlets that meet these requirements, remain the responsibility of the manufacturer.

1.3
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.

1.4
All references to pressure throughout this Standard are to be considered gauge pressure, unless otherwise specified.

1.5
Clause 2, Reference Publications contains a list of standards specifically referenced in this Standard, and sources from which these reference standards may be obtained.

1.6
This Standard contains SI (Metric) units corresponding to the yard/pound quantities, the purpose being to allow the standard to be used in SI (Metric) units. (IEEE/ASTM SI 10, American National Standard for Metric Practice, or ISO 80000-1:2009, Quantities and units — Part 1: General, is used as a guide in making metric conversion from yard/pound quantities.) If a value for a measurement and a corresponding value in other units are stated, the first stated value is to be regarded as the requirement. The given corresponding value may be approximate. If a value for a measurement and a corresponding value in other units are both specified as a quoted marking requirement, the first stated unit, or both, are to be provided.

1.7
In this Standard, “shall” is used to express a requirement, i.e., a provision that the user shall 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.
