1、Designation: E702 85 (Reapproved 2010)Standard Specification forMunicipal Ferrous Scrap1This standard is issued under the fixed designation E702; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision. A number i
2、n parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This specification covers the chemical and physicalrequirements of municipal ferrous scrap that are intended foruse by such industries listed a
3、s follows:1.1.1 Copper industry (precipitation process),1.1.2 Iron and steel foundries,1.1.3 Iron and steel production,1.1.4 Detinning industry, and1.1.5 Ferroalloy industry.1.2 The values stated in inch-pound units are to be regardedas standard. The values given in parentheses are mathematicalconve
4、rsions to SI units that are provided for information onlyand are not considered standard.1.3 Questions concerning material rejection, downgrading,and retesting based on failure to meet the requirements of thisspecification shall be dealt with through contractual arrange-ments between the purchaser a
