ASTM D3098 84 I 0757530 0028856 1 I I-37-13 I Designation:D 3098-84 AMERICAN SOCIETY FOR TESTING AND MATERIALS 1916 Race St.,Philadelphia,Pa.19103 Reprinted from the Annual Book of ASTM Standards,Copyright ASTM If not listed in the current combined index,will appear in the next edition.Standard Test Method for FINISH CONTENT OF WOVEN GLASS FABRIC,CLEANED TYPE FINISHES FOR PLASTIC LAMINATES AND AFTER FINISHED WITH EPOXY-FUNCTIONAL SILANE-This standard is issued under the fved designation D 3098;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.A superscript epsilon(c)indicates an editorial change since the last revision or reapproval.1.Scope 1.1 This test methodcovers the measurement of the amount of epoxy-functional silane finish applied to various styles of woven glass fabric that have been suitably cleaned to remove the oils and binders present on the yarn to make them suitable for use in plastic laminates.1.2 Glass fabrics with these finishes can be used with epoxy resin systems to produce lami-nates having properties suitable for use as single-and multi-layer circuit boards.NOTE 1-Typical epoxy-functional silane finishes are known as A-186-Beta(3,4-Epoxycyclohexyl)ethyl-trimethoxysilane:A-187-GammaG1ycidoxypropyltri-methoxysilane:Z-6040-Gamma-Glycidoxypropyltri-methox ysilane.NOTE 2-This test method is based on the use of a Lec0 No.589-600 Conductometric Carbon Determi-nator and Lec0 Induction Furnace,Laboratory Equip ment Co.,St.Joseph,Mich.,but any test method giving comparable results may be used.NOTE 3-The finish content may also be determined using automatic instruments not on the market when this test method was originally Written.The results obtained by these instruments comply with the require-ments of this test method although the procedure may differ.i.3 This standard may involve hazardous ma-terials,operations,and equipment.This standard does not purport to address all of the safetyprob-lems associated with its use.It is the responsibil-ity of whoever uses this standard to consult and establish appropriate sajty and health practices and determine the applicability of regulatory lrni-tations prior to use.2.Applicable Document 2.1 ASTMStandard:D4029 Specificatiqn for Finished Woven Glass Fabrics 3.Summary of Method 3.1 Specimens are burned with iron and tin accelerators in the presence of oxygen.The car-bon content is measured,which is a reliable indicatiqn of the amount of epoxy-functional silane finish on thg glass fabric.4.Signjficapce and Use 4.1 Th purpose of this test method is to pro-vide a means for determining the amount of epoxy-functiqnal silane finish on glass fabrics that have met the requirements of Specification D 4029 and whether it has been correctly applied.It is intended for use in specifications,product evaluation,and quality control.4.2 The epoxy-functional silane finish en-hances the handleability of the fabric and im-proves the mechanical properties of the glass fabric wheo used as a reinforcement in polyester laminates.5.t?aParas 5.1 Induction Furnace,Lec0 Model 521,522,5.2 Conductometric Carbon Determinator,or 523.eco No.515.This test method is under the jurisdiction of ASTM Com-mittee D20 on Plastics and is the direct responsibility of Sub committee D20.18 on Reinforced Thermosetting Plastics.Current edition approved Feb.24,1984.Published June 1984.Originally published as D 3098-72.Last previous edition D 3098-82.Annital Book o f ASThSiandards,Vol 07.02.1 NOTICE:This standard has either been superseded and replaced by a new version or discontinued.Contact ASTM International(www.astm.org)for the latest information.ASTM D3098 84 0759530 0028857 3 4 S P 5.3 Combustion Tube,Lec0 No.550-120.5.4 Carbon Crucible,Quartz-Enclosed,Lec0 5.5 Tin Accelerator,Lec0 No.501-76.5.6 Iron Accelerator,Lec0 No.501-77.5.7 Crucibles,Lec0 No.528-25.These cruci-bles are to be preignited at 1205C(2200F)in a tube furnace through which a stream of oxygen is flowing.After burning,the crucibles must be handled with tongs to prevent contamination with oil from the skin;the crucibles shall then be stored in a desiccator.5.8 Tube Furnace.5.9 Variable Tranflormer.5.10 Caution-Before attempting this deter-mination,the analyst must be thoroughly famil-iar with the“Instruction Manual for Operation of Lec0 No.589-600 Conductometric Carbon Determinator”and the“Instruction Manual for Operation of Lec0 Induction Furnace.”Princi-ples of the method are explained in the manuals.NO.550-182.6.Reagents and Materials 6.i Barium Hydroxide Solution-See In-struction Manual for Operation of Lec0 No.5 15 Conductometric Carbon Determination.”6.2 Mercury.6.3 Oxygen,cylinder.6.4 Standard Steel,NBS 166A.7.Procedure 7.1 Assemble the apparatus in accordance with Fig.V,“S”modification of the“In:struction Manual for Operation of Lec0 Induc-tion Furnaces.”7.2 Using a quartz-enclo
