18.1 For purposes of determining compliance with the specified limits for requirements of the properties listed in the following table, an observed value or a calculated value shall be rounded as indicated in accordance with the rounding method of Practice E29.Property Rounded Unit for Calculatedor Observed Value Chemical composition nearest unit in the last right-hand place of figures of the specified limit Hardness Electrical resistivity nearest unit in the last right-hand place of figures Electrical conductivity Tensile strength nearest ksi (5 MPa) Elongation: below 5 % nearest multiple of 0.5 % 5 % and over nearest 1 %AbstractThis 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:2CopperUNS No.2 PreviouslyUsedDesignation Type of Copper C10100 OFE Oxygen-free, electronic C10200 OF Oxygen-free without residual deoxidants C10300 — Oxygen-free, extra low phosphorus C10400, C10500, C10700 OFS Oxygen-free, silver bearing C11000 ETP Electrolytic tough pitch C11300, C11400, C11600 STP Silver-bearing tough pitch C12000 DLP Phosphorized, low residual phosphorus1.2 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.
