ASTM B 216 Standard Specification for Tough-Pitch Fire-Refined Copper—Refinery Shapes
ASTM B 216 火法精炼工业纯铜标准规范.精炼型材

This specification establishes the requirements for tough-pitch fire-refined copper wire bars, cakes, slabs, and billets for fabricating into wrought products and ingot and ingot bars for use in the manufacture of copper and copper alloy castings. This copper is not intended for electrical purposes. Any copper may be used that will yield a product with a chemical composition conforming to the requirements specified. The chemical composition test shall be made to conform with the product specification 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.
Significance and Use
Calculated values shall be rounded to the nearest unit in the last right-hand significant digit used in expressing the limiting value in accordance with the rounding method in Practice E29.
 
1. Scope
1.1 This specification establishes the requirements for tough-pitch fire-refined copper wire bars, cakes, slabs, and billets for fabricating into wrought products and ingot and ingot bars for use in the manufacture of copper and copper alloy castings. This copper is not intended for electrical purposes.
1.2 Copper under this specification corresponds to the designation “FRTP” (UNS C12500) as shown in Classification B224. This copper may also be used to produce copper, corresponding to the designation “DPTE” (UNS C14520).
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 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.5 The following safety hazard caveat pertains only to the test method described in the annex 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.
A1.1.1 This test method covers the analysis of antimony, arsenic, bismuth, lead, nickel, selenium, and tellurium in tough-pitch fire-refined copper.
A1.1.2 This standard may involve hazardous materials, operations, and equipment. This standard does not purport to address all of the safety concerns 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.
