ASTM D5359-98(R2021) pdf free download.Standard Specification for Glass Cullet Recovered from Waste for Use in Manufacture of Glass Fiber
1. Scope
1.1 This specification describes glass cullet recovered from municipal waste destined for disposal. The recovered cullet is intended for use in the manufacture of glass fiber used for insulation-type products. 1.2 This international standard was developed in accor- dance with internationally recognized principles on standard- ization established in the Decision on Principles for the Development of International Standards, Guides and Recom- mendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
2. Referenced Documents

3. Terminology
3.1 For definitions of terms used in this specification, refer to Terminology C162.
4. General Requirements
4.1 Glass cullet from municipal waste is primarily soda- lime bottle glass and shall be one of three grades depending upon the total usage rate requirement of the user. The three grades shall satisfy the following chemical composition, color mix, contamination, and particle size requirements as listed in Section 4: 4.2 Chemical Composition—See Table 1. 4.3 Color Mix—Color is an indicator of the oxidation state of container cullet. SO 3 gas solubility in the glass melt is a function of the glass oxidation state. Changes in the oxidation state of cullet added to the fiberglass batch can shift the glass oxidation state causing the release of dissolved SO 3 gas, which can upset the furnace. Achange in the glass oxidation state also means a change in the glass FeO content. This affects the heat transfer in the melt and can affect furnace efficiency and glass quality. See Table 2. 4.4 Contaminants—Free metals, magnetic or nonmagnetic, are not oxidized in the glass melting process and, therefore, are insoluble. Metals will pool on the furnace floor and leak through joints causing premature wear of refractories and electrical shorts, which can lead to glass leaks. Some metals will attack and destroy precious metal skimmers and thermo- couples and molybdenum electrodes. Examples are silver, tin, lead, and aluminum.4.4.1 Other inorganic materials and refractories will not melt in the glass melting process. Other inorganics can be porcelains, ceramics, or high-temperature glasses. Refractories can be remnants of furnace construction materials or minerals contained as unmelted inclusions in the cullet. See Table 3. The container cullet mixture must not contain glass types or other materials whose composition contains anything that is either harmful to the fiberglass production process or which affects the user’s ability to meet Federal or state environmental, safety, or health laws. Examples of such materials are anything which contains elements or oxides of phosphorus, arsenic, antimony, and chlorides. 4.5 Particle Size—For all grades of cullet, the particle size shall be 100 % < 1 ⁄ 4 in. and <15 % <200 mesh. The specification for the particle size distribution between these two end points shall be agreed to on an individual basis between the cullet supplier and the cullet user.
5. Sampling and Testing
5.1 Sampling and testing shall be in accordance with Test Methods E688.
