1.1This specification establishes the requirements for seamless copper tube in coils, suitable for use in refrigeration and air conditioning or other uses, such as oil lines and gasoline lines.
1.2Units—The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.3The tube shall be produced of the following coppers:
| Copper Alloy | Previously Used | Type of Copper |
| C10200 | OF | Oxygen-free without residual deoxidantsA |
| C10300 | ... | Oxygen-free, extra low phosphorusA |
| C10800 | ... | Oxygen-free, low phosphorusA |
| C12000 | DLP | Phosphorized, low residual phosphorus |
| C12200 | DHP | Phosphorized, high residual phosphorus |
1.4The following safety hazards caveat pertains to the test method 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.
1.5This 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.
