1、Designation: E 708 79 (Reapproved 2006)Standard Specification forWaste Glass as a Raw Material for the Manufacture of GlassContainers1This standard is issued under the fixed designation E 708; the number immediately following the designation indicates the year oforiginal adoption or, in the case of
2、revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope1.1 This specification covers particulate glass (cullet mate-rial, recovered from waste destined fo
3、r disposal, smaller than 6mm intended for reuse as a raw material in the manufacture ofglass containers.1.2 The values stated in SI units are to be regarded as thestandard.

General Requirements5.1 The sample shall show no drainage of liquid and benoncaking and free flowing.Amoisture content of less than 0.5weight % is required to meet the free-flowing characteristics ofa cullet that is
8、 predominantly of smaller particle size, 1.18-mm(No 16) sieve or smaller.5.2 Screen SizeNo material shall be retained on a 6-mm(14-in.) screen. Material not exceeding 15 weight % shall passthrough a 106-m (No. 140) screen.5.3 Organic MaterialsThe total content of organic mate-rials, as measured in a
9、ccordance with Section 6 shall notexceed 0.2 weight % of dry sample, except for color-mixedglass where the content of organic material may exceed 0.2weight %. However, a content of organic material greater than0.2 weight % must be held within a tolerance of 60.05weight %, with a maximum organic limi
