Designation:D535998(Reapproved 2021)Standard Specification forGlass Cullet Recovered from Waste for Use in Manufactureof Glass Fiber1This standard is issued under the fixed designation D5359;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 This specification describes glass cullet recovered frommunicipal waste destined for disposal.The recovered cullet isintended for use in the manufacture of glass fiber used forinsulation-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 theDevelopment of International Standards,Guides and Recom-mendations issued by the World Trade Organization TechnicalBarriers to Trade(TBT)Committee.2.Referenced Documents2.1 ASTM Standards:2C162 Terminology of Glass and Glass ProductsD4129 Test Method for Total and Organic Carbon in Waterby High Temperature Oxidation and by CoulometricDetectionE688 Test Methods for Waste Glass as a Raw Material forGlass Manufacturing(Withdrawn 2019)33.Terminology3.1 For definitions of terms used in this specification,referto Terminology C162.4.General Requirements4.1 Glass cullet from municipal waste is primarily soda-lime bottle glass and shall be one of three grades dependingupon the total usage rate requirement of the user.The threegrades shall satisfy the following chemical composition,colormix,contamination,and particle size requirements as listed inSection 4:4.2 Chemical CompositionSee Table 1.4.3 Color MixColor is an indicator of the oxidation stateof container cullet.SO3gas solubility in the glass melt is afunction of the glass oxidation state.Changes in the oxidationstate of cullet added to the fiberglass batch can shift the glassoxidation state causing the release of dissolved SO3gas,whichcan upset the furnace.Achange in the glass oxidation state alsomeans a change in the glass FeO content.This affects the heattransfer in the melt and can affect furnace efficiency and glassquality.See Table 2.4.4 ContaminantsFree metals,magnetic or nonmagnetic,are not oxidized in the glass melting process and,therefore,areinsoluble.Metals will pool on the furnace floor and leakthrough joints causing premature wear of refractories andelectrical shorts,which can lead to glass leaks.Some metalswill 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 notmelt in the glass melting process.Other inorganics can beporcelains,ceramics,or high-temperature glasses.Refractoriescan be remnants of furnace construction materials or mineralscontained as unmelted inclusions in the cullet.See Table 3.4.4.1.1 The container cullet mixture must not contain glasstypes or other materials whose composition contains anythingthat is either harmful to the fiberglass production process orwhich affects the users ability to meet Federal or stateenvironmental,safety,or health laws.Examples of suchmaterials are anything which contains elements or oxides ofphosphorus,arsenic,antimony,and chlorides.4.5 Particle SizeFor all grades of cullet,the particle sizeshall be 100%14in.and 15%15%in batchOxideWeight%Range%Weight%Range%Weight%Range%SiO26877NA68771.0068771.00Al2O307NA070.50070.50CaO515NA5150.505150.50MgO05NA050.50050.50Na2O818NA8180.508180.50K2O04NA040.50040.50Fe2O30.5NA0.50.050.50.05Cr2O30.2NA0.150.030.10.02SO30.4NA0.30.030.20.02All otheroxides0.5NA0.30.050.10.02CA0.15NA0.100.020.050.01H2O0.5NA0.50.050.50.05LOI0.45NA0.300.0515%in batchColorWeight%Range%Weight%Range%Weight%Range%Flint0100NA0100501003dGreen0100NA0100501003Amber50NA30515%in batchContaminant TypeWeight%Weight%Weight%Magnetic Material0.30.20.1Nonmagnetic Metals0.010.0050.005Other InorganicMaterial+12 MeshNA0.00.0+20 MeshNA0.20.120 MeshNA0.30.2Refractories+12 MeshNA0.00.0+20 MeshNA0.20.120 MeshNA0.30.2D5359 98(2021)2ASTM International takes no position respecting the validity of any patent rights asserted in connection with any item mentionedin this standard.Users of this standard are expressly advised that determination of the validity of any such patent rights,and the riskof 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 andif not revised,either reapproved or withdrawn.Your comments are invited either for revision of this standard or for additional standardsand should be addressed to ASTM International Headquarters.Your comments will receive careful consideration at a meeting of theresponsible technical committee,which you may attend.If you feel that your comments have not rec
