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 are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.

1.3 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, health, and environmental 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.
