1.1 These test methods cover the quantitative chemical analysis of soda-lime and borosilicate glass compositions for both referee and routine analysis. This would be for the usual constituents present in glasses of the following types: ( 1 ) soda-lime silicate glass, ( 2 ) soda-lime fluoride opal glass, and ( 3 ) borosilicate glass. The following common oxides, when present in concentrations greater than indicated, are known to interfere with some of the determinations in this method: 2 % barium oxide (BaO), 0.2 % phosphorous pentoxide (P 2 O 5 ), 0.05 % zinc oxide (ZnO), 0.05 % antimony oxide (Sb 2 O 3 ), 0.05 % lead oxide (PbO). 1.2 The analytical procedures, divided into two general groups, those for referee analysis, and those for routine analysis, appear in the following order: Sections Procedures for Referee Analysis: Silica 10 BaO, R 2 O 2 (Al 2 O 3 + P 2 O 5 ), CaO, and MgO 11 – 15 Fe 2 O 3 , TiO 2 , ZrO 2 by Photometry and Al 2 O 3 by Com- plexiometric Titration 16 – 22 Cr 2 O 3 by Volumetric and Photometric Methods 23 – 25 MnO by the Periodate Oxidation Method 26 – 29 Na 2 O by the Zinc Uranyl Acetate Method and K 2 O by the Tetraphenylborate Method 30 – 33 SO 3 (Total Sulfur) 34 – 35 As 2 O 3 by Volumetric Method 36 – 40 Procedures for Routine Analysis: Silica by the Single Dehydration Method 42 – 44 Al 2 O 3 , CaO, and MgO by Complexiometric Titration, and BaO, Na 2 O, and K 2 O by Gravimetric Method 45 – 51 BaO, Al 2 O 3 , CaO, and MgO by Atomic Absorption; and Na 2 O and K 2 O by Flame Emission Spectroscopy 52 – 59 SO 3 (Total Sulfur) 60 B 2 O 3 61 – 62 Fluorine by Pyrohydrolysis Separation and Specific Ion Electrode Measurement 63 – 66 P 2 O 5 by the Molybdo-Vanadate Method 67 – 70 Colorimetric Determination of Ferrous Iron Using 1,10 Phenanthroline 71 – 76 1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. ====== Significance And Use ====== 3.1 These test methods can be used to ensure that the chemical composition of the glass meets the compositional specification required for the finished glass product. 3.2 These test methods do not preclude the use of other methods that yield results within permissible variations. In any case, the analyst should verify the procedure and technique employed by means of a National Institute of Standards and Technology (NIST) standard reference material having a component comparable with that of the material under test. A list of standard reference materials is given in the NIST Special Publication 260 , 3 current edition. 3.3 Typical examples of products manufactured using soda-lime silicate glass are containers, tableware, and flat glass. 3.4 Typical examples of products manufactured using borosilicate glass are bakeware, labware, and fiberglass. 3.5 Typical examples of products manufactured using fluoride opal glass are containers, tableware, and decorative glassware.
