This specification covers seamless copper bus pipe and tube intended for use as electrical conductors. The material shall be manufactured by such hot-working, cold-working, and annealing processing as to produce a uniform, seamless wrought structure in the finished product. The method of manufacture shall be such that the finished material conforms to the specified temper properties. The material shall conform to the requirements for the copper UNS no. as specified. The material shall be furnished in either the O60 (soft anneal) or H80 (hard drawn) temper. The material shall conform to the maximum electrical resistivity requirements prescribed. The product shall conform to the prescribed mechanical property requirements. The product shall conform to the prescribed bend testing requirements. The test specimens of material designated as Copper UNS Nos. C10100, C10200, C10300, C10400, C10500, C10700, and C12000 shall be free of cuprous oxide. When tested, material designated as Copper UNS nos. C10100, C10200, C10300, C10400, C10500, C10700, and C12000 shall pass the embrittlement test. The product shall be passed through an eddy-current testing unit adjusted to provide information on the suitability of the product for the intended application.
1.1 This specification establishes the requirements for seamless copper bus pipe and tube intended for use as electrical conductors.
1.1.1 The product shall be made from one of the following coppers, as denoted in the ordering information:2
| Copper | Previously | Type of Copper |
|
|
|
|
| C10100 | OFE | Oxygen-free, electronic |
| C10200 | OF | Oxygen-free without residual deoxidants |
| C10300 | — | Oxygen-free, extra low phosphorus |
| C10400, C10500, | OFS | Oxygen-free, silver bearing |
| C11000 | ETP | Electrolytic tough pitch |
| C11300, C11400, | STP | Silver-bearing tough pitch |
| C12000 | DLP | Phosphorized, low residual phosphorus |
1.2 Unless otherwise specified, any one of the above coppers may be furnished.
1.3 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.
1.4 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.
