General

This Standard covers requirements for manually operated metallic valves sizes NPS ½ through NPS 2, for outdoor installation as gas shut-off valves at the end of the gas service line and before the gas regulator and meter where the designated gauge pressure of the gas piping system does not exceed 125 psi (8.6 bar). The Standard applies to valves operated in a temperature environment between −20°F and 150°F (−29°C and 66°C).

Design

This Standard sets forth the minimum capabilities, characteristics, and properties, which a valve at the time of manufacture must possess, in order to be considered suitable for use in gas piping systems. Details of design and manufacture (other than those stated in this Standard, including such design and production tests that will produce a valve that will have the required capabilities to meet this Standard) remain the responsibility of the manufacturer.

Standards and Specifications

Standards and specifications adopted by reference in this Standard and the names and addresses of the sponsoring organizations are shown in Nonmandatory Annex A. It is not considered practical to refer to a specific edition of each of the standards and specifications in the individual references. Instead the specific edition references are included in Nonmandatory Annex A. A product made in conformance with a prior edition of reference standards and in all other aspects conforming to this Standard will be considered to be in conformance even though the edition reference may be changed in a subsequent revision of this Standard.

Quality Systems

Nonmandatory requirements relating to the manufacturer's Quality System Program are described in Non-mandatory Annex B.

Convention

For the purpose of determining conformance with this Standard, the convention for fixing significant digits where limits, maximum or minimum values, are specified shall be "rounding off" as defined in ASTM Practice E 29. This requires that an observed or calculated value shall be rounded off to the nearest unit in the last right-hand digit used for expressing the limit. Decimal values and tolerances do not imply a particular method of measurement.

Codes and Regulations

A valve used under the jurisdiction of the Code of Federal Regulation (CFR) such as Title 49 Part 192, the ASME Code for Pressure Piping such as ASME B31.8, or the National Fuel Gas Code, Z223.1, is subject to any limitation of that code or regulation.
