ASTM B187/B187M-20 - 1.6.2020
 
1. Scope

1.1This specification2 establishes the requirements for copper conductor bar, rod, and shapes for electrical (bus) applications and rod, bar, and shapes for general applications.

1.1.1The products for electrical (bus) applications shall be made from the following coppers:3

Copper UNS No.3

Reference Designation

C10100

OFE

C10200

OF

C10300

OFXLP

C10400, C10500, C10700

OFS

C10920, C10930, C10940

C11000

ETP

C11020

FRHC

C11300, C11400, C11500, C11600

STP

C12000

DLP

1.1.1.1The product may be furnished from any copper listed unless otherwise specified in the contract or purchase order.

1.2The product for general applications shall be made from any of the coppers in 1.1.1 or the following coppers:

Copper UNS No.3

Reference Designation

C10800

OFLP

C12200

DHP

1.2.1The product may be furnished from any copper listed above unless otherwise specified in the contract or purchase order. Other coppers may be used upon agreement between the supplier and purchaser.

1.3UnitsThe 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.

Note 1:Material for hot forging will be found in Specification B124/B124M.

1.4This 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.
