    Significance and Use

    18.1 For purpose of determining compliance with the specified limits for requirements of the properties listed in Table 5, an observed value or calculated value shall be rounded as indicated in accordance with the rounding method of Practice E29.

    1. Scope

    1.1 This specification establishes the requirements for Type GAS seamless Copper UNS No. C12200 tube for use in above ground natural gas and liquified petroleum (LP) gas fuel distribution systems, commonly assembled with flared fittings or brazed joints.

    Note 1: Tube temper, size, and joining method are determined by installation code requirements.

    1.2 Units—The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units which are provided for information only and are not considered standard.

    1.3 The following safety hazard caveat pertains only to the test method(s) portion, Section 17, of this specification. This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

    1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
