ASTM B75 / B75M - 11 standard specification for seamless copper tube

0

Source: ASTM International

This specification establishes the requirements for seamless round, rectangular, and square copper tube suitable for general engineering applications. The tube shall be manufactured by such hot- and cold-working processes as to produce a homogeneous, uniform wrought structure in the finished product. It shall be cold drawn to the finished size and wall thickness. The requirements and size availability of tube in the tempers shall conform to the specified requirements. Tensile and yield strength test, Rockwell hardness test, expansion test, microscopical examination, hydrogen embrittlement, electromagnetic test, hydrostatic pressure test, pneumatic pressure test, electrical resistivity, and chemical composition shall be made to conform to specified requirements.

This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.

1. Scope

1.1 This specification 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 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 The following hazard statement pertains only to the test methods described in Sections 20.5.2.1, 21.2.9, and 21.2.10 of 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.
