ASTM B5-00

Standard Specification for High Conductivity Tough-Pitch Copper Refinery Shapes

SCOPE
1.1 This specification establishes the requirements for high conductivity tough-pitch copper wire bars, cakes, slabs, billets, ingots, and ingot bars.  
1.2 Copper under this specification corresponds to the designations "ETP" (UNS C11000) and "FRHC" (UNS C11020) as shown in Classification B224. These coppers may also be used to produce coppers corresponding to the following: Copper UNS No. Classification B 224 Designation C11300, C11400, C11500 ∧ C11600 STP C12000 DLP C12200 DHP C12300 DHPS C14500 DPTE
1.3 Although this specification includes certain UNS designations as described in Practice E527, these designations are for cross reference only and are not specification requirements. Therefore in case of conflict, this ASTM specification shall govern.  
1.4 In this specification inch-pound units are the standard except for electrical resistivity which is expressed in SI units. The values given in parentheses are for information only.
