Abstract

This specification covers a group of general requirements for wrought seamless copper and copper alloy tube. The material shall be produced by either hot or cold working operations, or both, and shall be finished, unless otherwise specified, by such cold working and annealing or heat treatment as necessary to meet the properties specified. Dimensional requirements such as wall thickness are specified. The sampling requirements including lot size, portion size, and selection of sample pieces are given. Requirements for chemical analysis, and tension, microscopical examination, Rockwell hardness, grain size, expansion (pin), mercurous nitrate, and electrical resistivity tests are detailed. The material shall conform to the prescribed chemical composition, hardness, electrical resistivity, tensile strength, yield strength, elongation, and grain size.

Scope

1.1 This specification covers a group of general requirements common to several wrought product specifications. Unless otherwise specified in the purchase order, or in an individual specification, these general requirements shall apply to copper and copper-alloy tube supplied under Specifications B68/B68M, B75/B75M, B135/B135M, B466/B466M, B643 and B743.

1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.

1.3 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.
