ASTM B956-07e1

This document is not anASTM standard and is intended only to provide the user of anASTM 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:B956–07 Designation: B 956 – 07
Standard Specification for
Welded Copper and Copper-Alloy Condenser and Heat
1
Exchanger Tubes with Integral Fins
This standard is issued under the fixed designation B 956; 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 (e) indicates an editorial change since the last revision or reapproval.

e NOTE—Added table reference to 5.2.4.
1. Scope
1.1 Thisspecificationestablishestherequirementsforheatexchangertubesmanufacturedfromforge-weldedcopperandcopper
alloy tubing in straight lengths on which the external or internal surface, or both, has been modified by cold forming process to
produce an integral enhanced surface for improved heat transfer.
1.2 Units—The values stated in either inch-pounds units or SI units are to be regarded separately as the standard. Within the
text, the SI units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system shall
be used independently of the other. Combining values from the two systems could result in nonconformance with the specification.
1.3 The tubes are typically used in surface condensers, evaporators, and heat exchangers.
1.4 The product shall be produced of the following coppers or copper alloys, as specified in the ordering information.
Copper or Copper Alloy

NOTE 1—Designations listed in Classification B 224.
1.5 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 and health practices and determine the applicability of regulatory limitations prior to use.
