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 (P2O5), 0.05 % zinc oxide (ZnO), 0.05 % antimony oxide (Sb2O3), 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:

Procedures for Referee Analysis:
BaO, R2O2 (Al2O3 + P2O5), CaO, and MgO11-15
Fe2O3, TiO 2, ZrO2 by Photometry and Al2O3 by Complexio-
metric Titration
Cr2O3 by Volumetric and Photometric Methods23-25
MnO by the Periodate Oxidation Method26-29
Na2O by the Zinc Uranyl Acetate Method and K2O by the Tetraphenylborate Method 30-33
SO3 (Total Sulfur)34 to 35
As2O3 by Volumetric Method36-40
Procedures for Routine Analysis:
Silica by the Single Dehydration Method42-44
Al2O3, CaO, and MgO by Complexiometric Titration, and BaO, Na2O, and K2O by Gravimetric Method45-51
BaO, Al2O3, CaO, and MgO by Atomic Absorption; and Na2O and K 2O by Flame Emission Spectroscopy52-59
SO3 (Total Sulfur)60
B2O361 to 62
Fluorine by Pyrohydrolysis Separation and Specific Ion Electrode Measurement63-66
P2O5 by the Molybdo-Vanadate Method67-70
Colorimetric Determination of Ferrous Iron Using 1,10 Phenan throline71-76

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 and health practices and determine the applicability of regulatory limitations prior to use.
