ASTM B75/B75M-11 - 15.10.2011
 
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.
