1.1 This specification covers particulate glass (cullet material, recovered from waste destined for disposal, smaller than 6 mm intended for reuse as a raw material in the manufacture of glass containers.

2.1 ASTM Standards

3.1 first glass cullet - a particulate glass material that contains no more than 0.1 weight % Fe 2 O 3 or 0.0015 weight % Cr 2 O 3, as determined by chemical analysis.

3.2 For definitions of other terms used in this specification, refer to Definitions C 162.

4.1 The following requirements qualify the glass lot to be used for direct use in soda-lime glass container manufacturing. Sample should be prepared and examined in accordance with Methods E 688.

NOTE1 -A preponderant proportion of glass cullet will be soda-lime bottle glass, the glass cullet having a composition as follows, as determined by Method C 169.

NOTE2 -All percents referred to in this specification are weight percents.

5.1 The sample shall show no drainage of liquid and be noncaking and free flowing. A moisture content of less than 0.5 weight % is required to meet the free-flowing characteristics of a cullet that is predominantly of smaller particle size, 1.18-mm (No. 16) sieve or smaller.

5.2 Screen Size - No material shall be retained on a 6-mm (1/4-in.) screen. Material not exceeding 15 weight % shall pass through a 106- m m (No. 140) screen.

5.3 Organic Materials - The total content of organic materials, as measured in accordance with Section 6 shall not exceed 0.2 weight % of dry sample, except for color-mixed glass where the content of organic material may exceed 0.2 weight %. However, a content of organic material greater than 0.2 weight % must be held within a tolerance of + 0.05 weight %, with a maximum organic limit of 0.4 weight %.

5.4 Magnetic Materials -The total magnetic materials shall not exceed 0.05 weight % of dry sample weight for flint glass and 0.14 weight % for colored glass of dry sample weight in accordance with Section 6.

5.5 Permissible Color Mix for Color Sorted Glass Cullet by Weight:

5.6 Other Inorganic Material (such as non-magnetic metals or refractories) -As measured, material larger than 850- m m (No. 20) screen size shall not exceed 0.1 % of the dry sample weight. Material smaller than 850- m m screen size shall not exceed 0.5 % of the dry sample weight.

6.1 Sampling and testing shall be in accordance with Methods E 688.

The American Society for Testing and Materials takes no position respecting the validity of any patent rights assured in connection with any item mentioned in this standard. Users of this standard are expressly advised that determination of the validity of any such patent rights, and the risk of infringement of such rights, are entirely their own responsibility.

This standard is subject to revision at any time by the responsible technical committee and must be reviewed every five years and if not revised, either reapproved or withdrawn. Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM Headquarters. Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend. If you feel that your comments have not received a fair hearing you should make your views known to the ASTM Committee on Standards 1916 Race St., Philadelphia, Pa. 19103, which will schedule a further hearing regarding your comments. Failing satisfaction there, you may appeal to the ASTM Board of Directors.
