ASTM E702-21

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
Designation: E702 − 85 (Reapproved 2015) E702 − 21
Standard Specification for
1
Municipal Ferrous Scrap
This standard is issued under the fixed designation E702; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (´) indicates an editorial change since the last revision or reapproval.
1. Scope
1.1 This specification covers the chemical and physical requirements of municipal ferrous scrap that are intended for use by such
industries listed as 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, and
1.1.5 Ferroalloy industry.
1.2 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.
1.3 Questions concerning material rejection, downgrading, and retesting based on failure to meet the requirements of this
specification shall be dealt with through contractual arrangements between the purchaser and the supplier.
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.

3.2 Definitions:Definitions of Terms Specific to This Standard:
3.2.1 metallic yield—yield, n—the weight percent of the municipal ferrous scrap that is generally recoverable as metal or alloy.
3.2.2 municipal ferrous scrap—scrap, n—ferrous waste that is collected from industrial, commercial, or household sources and
destined for disposal facilities. Typically, municipal ferrous scrap consists of a metal or alloy fraction, a combustible fraction, and
an inorganic noncombustible fraction that includes metal oxides.
3.2.3 total combustibles—combustibles, n—materials that include paints, lacquers, coatings, plastics, etc., associated with the
original ferrous product, as well as combustible materials (paper, plastic, textiles, etc.) which become associated with the ferrous
product after it is manufactured.
4. Chemical Composition
4.1 Municipal ferrous scrap shall conform to the requirements as to chemical composition for the respective end uses prescribed
in Table 1.
4.2 The chemical requirements listed in Table 1 are based on melt analyses except where noted.
5. Physical Properties
5.1 Municipal ferrous scrap shall conform to the physical properties for the respective end uses prescribed in Table 2.
6. Test Methods
6.1 Determine the physical and chemical requirements of municipal ferrous scrap in accordance with Test Methods E701.
