Foreword

The standard reference ASTMC169-92 (2000) "soda-lime and borosilicate glass chemical analysis test methods", JISR3101-1995 "Sodium, calcium and magnesium silicate glass chemical analysis." This standard replaces GB/T 1549-1994 "sodium calcium aluminosilicate glass boron chemical analysis." This standard compared with GB/T 1549-1994, the main technical changes as follows. --- Expanding the scope of application. The standard name be changed to "fiberglass chemical analysis methods," the scope of application in addition to including the original E (E) and the outer glass base (C) glass, further comprising a boron-free alkali (ECR) glass, alkali-resistant (AR) glass, high base (A) glass Glass, high silica glass, high-strength (S) glass, basalt fiber and glass wool, rock wool, slag wool, aluminum silicate fiber cotton glass state. --- Increased manganese oxide, zirconia, lithium, antimony total, total sulfur, phosphorus pentoxide, strontium oxide, zinc oxide, ceria and barium, cadmium, Chromium, mercury, lead and test items. --- Increased by atomic absorption spectrophotometry of total iron, calcium oxide and magnesium oxide, hydrogen peroxide spectrophotometric determination of the spectral dioxide Titanium, with fluoride ion selective electrode method, the determination of total arsenic by inductively coupled plasma atomic emission spectrometry and other detection method. --- Increased by inductively coupled plasma atomic emission spectrometry aluminum oxide, calcium oxide, magnesium oxide, zirconium dioxide, total iron and Titania Appendix A. --- The original determination of ferrous oxide redox titration with potassium dichromate to  phenanthroline spectrophotometry method. --- In the method of determination of EDTA complexometric titration of calcium oxide and magnesium oxide, the only original triethanolamine to mask interfering ions Triethanolamine and hydroxylamine hydrochloride joint masking interfering ions. --- In the gravimetric method - Silicon molybdenum blue spectrophotometric method for determination of silicon dioxide, the silicon molybdenum yellow color from the original acidity 0.10mol/L increased to 0.20mol/L; increased operating silicomolybdenum dark yellow color when, in order to eliminate interference photochemical reduction; the Silicon molybdenum yellow coloration process were also placed in a plastic cup, eliminating the interference of F-. --- In phenanthroline  morpholino spectrophotometric method to determine the total iron, increasing the use of acetic acid - sodium acetate buffer solution pH adjusting color The method to accommodate the requirements of the determination of calcium oxide content of the glass. --- In the method of spectrophotometric determination of total arsenic in arsenic molybdenum blue spectrophotometric, the amount before the color standard colorimetric series was added dropwise a solution of potassium permanganate Dropwise to the solution to microscopic red, expanded the scope of work of the curve, and increased sample weight and volume dispensing.
