(Specification)Standard Specification for Seamless Copper Tube
Standard Specification for Seamless Copper Tube
ABSTRACT
This specification establishes the requirements for seamless round, rectangular, and square copper tube (UNS Nos. C10100, C10200, C10300, C10800, C12000, and C12200) suitable for general engineering applications. The material of manufacture shall be billets, cast bars, or tube. The tube shall be manufactured by hot- and cold-working processes, shall be cold drawn to the finished size and wall thickness, and shall be supplied in cold-drawn or annealed temper condition. The material shall conform to the chemical composition requirements prescribed for copper, phosphorus, and arsenic, as determined by chemical analysis, and to the mechanical property requirements including tensile strength, yield strength, Rockwell hardness, and straightening. Requirements for grain size, electrical mass resistivity, and dimensions are specified. The following test methods are detailed: grain size, electrical resistivity, tensile and yield strength, and hardness tests, expansion test for round table, microscopical examination, test for hydrogen embrittlement, and nondestructive tests such as electromagnetic (eddy-current), hydrostatic, and pneumatic pressure tests.
SCOPE
1.1 This specification2 establishes the requirements for seamless round, rectangular, and square copper tube suitable for general engineering applications.
1.1.1 Tubes made from any of the following Copper UNS No. designations shall be supplied unless otherwise specified in the contract or purchase order:
Copper UNS No.
Type of Copper
C10100
Oxygen-free electronic
C10200
Oxygen-free without residual deoxidants
C10300
Oxygen-free, extra low phosphorus
C10800
Oxygen-free, low phosphorus
C12000
Phosphorus deoxidized, low residual phosphorus
C12200
Phosphorus deoxidized, high residual phosphorus
1.2 Units—The values stated in either inch-pound units or SI units are to be regarded separately as standard. Within the text, SI units are shown in brackets. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.
1.3 The following safety hazard caveat pertains only to the test methods described in 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.

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
