ASTM B466/B466M-18

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.
Designation: B466/B466M − 14 B466/B466M − 18
Standard Specification for
Seamless Copper-Nickel Pipe and Tube
This standard is issued under the fixed designation B466/B466M; the number immediately following the designation indicates the year
of original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval.
A superscript epsilon (´) indicates an editorial change since the last revision or reapproval.
This standard has been approved for use by agencies of the U.S. Department of Defense.
1. Scope*
1.1 This specification establishes the requirements for seamless copper-nickel pipe and tube in straight lengths, suitable for
general engineering purposes. The alloys involved are copper alloys UNS Nos. C70400, C70600, C70620, C71000, C71500,
C71520, and C72200.
1.1.1 Copper alloys UNS Nos. C70620 and C71520 are intended for product that will be subsequently welded.
1.2 Units—Values stated in either SI units or inch-pound units are to be regarded separately as standard. Within the text, SI units
are shown in brackets. 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 nonconformance with the specification.
1.3 The following safety hazard caveat pertains only to the test methods described in this specification:
1.3.1 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 safety, health, and healthenvironmental 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.
