Appendix A Designation: E 708-79 Standard
					 Specification for Waste Glass As a Raw Material for the Manufacture of Glass
					 Containers1
This standard is issued under the fixed designation E 708:
					 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.
1. Scope
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. Applicable Documents
2.1
ASTM Standards
.
C 162 Definitions of Terms Relating to Glass and Glass
					 Products2
C 169 Chemical Analysis of Soda-Lime and Borosilicate
					 Glass2
C 429 Sieve Analysis of Raw Materials for Glass
					 Manufacture2

					 of Glass Containers3
3. Definitions
3.1
first glass cullet
-- a particulate
					 glass material that contains no more than 0.1 weight %
					 Fe2O3 or 0.0015 weight %
					 Cr2O3, as determined by chemical
					 analysis.
3.2 For definitions of other terms used in this
					 specification, refer to Definitions C 162.
4. Representative Sample
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.
NOTE 1--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.
Oxide
Composition,
							 Weight %
SiO2
66 to
							 75
A12O3
1 to
							 7
CaO + MgO
9 to 13
Na2O
12 to
							 16
NOTE 2--All percents referred to in this specification are
					 weight percents.
5. General Requirements.
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-[MICRO]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:
5.5.1
Amber Glass Cullet:
90 to 100
% amber
0 to 10
% flint
0 to 10
% green
0 to 5
% other colors
5.5.2
Green Glass Cullet:
50 to 100
% green
0 to 35
% amber
0 to 15
% flint
0 to 4
% other colors
5.5.3
Flint Glass Cullet:
95 to 100
% flint
0 to 5
% amber
0 to 1
% green
0 to 0.5
% other colors
5.5.3.1 Percents above 0.1 weight % of
					 Fe2O3 or 0.0015 weight % of
					 Cr7O3, or both, as determined by
					 chemical analysis shall be considered mixed color glass. These limits are
					 consistent with industry experience on raw material.
5.5.3.2 Flint glass cullet may contain up to 1 weight %
					 emerald green or 10 weight % Georgia green, or a combination within the limits:
					 1 % Georgia green = 0.1 % emerald green.
5.6
Other Inorganic Material
(such as
					 non-magnetic metals or refractories)--As measured, material larger than
					 850-[MICRO]m (No. 20) screen size shall not exceed 0.1 % of the dry sample
					 weight. Material smaller than 850-[MICRO]m screen size shall not exceed 0.5 %
					 of the dry sample weight.
5.6.1
Refractories
--Based upon U.S. series
					 screen size and sample weight, the following refractory particle limits shall
					 apply for each screen fraction as stated below.
+20 mesh
1 particle per 18-kg
							 (40-lb) sample
-20, +40 mesh
2 particles per 450-g
							 (1-lb) sample
-40, +60 mesh
20 refractory
							 particles per 450-g (1-lb) sample
5.6.2
Nonmagnetic Metals:
+20 mesh
1 particle per 18-kg
							 (40-lb) sample
Upon failure to meet the previously stated specification
					 limits, retesting is permissible.
6. Sampling and Testing
6.1 Sampling and testing shall be in accordance with
					 Methods E 688.
