7. Reagents
7.1 Purity of Reagents - Reagent grade chemicals shall be used in all tests. Unless otherwise indicated, it is intended that all reagents shall conform to the specifications of the Committee on Analytical Reagents of the American Chemical Society, where such specifications are available. Other grades may be used, provided that it is first ascertained that the reagent is of sufficiently high purity to permit its use without lessening the accuracy of the determination.
7.2 Purity of Water - Unless otherwise indicated, references to water shall be understood to mean reagent water conforming to Specification D1193, Type III.
7.3 Isopropyl Alcohol.
NOTE 1 - Warning: Flammable.
7.4 Solvent Rinse Solution, of the following composition by volume:
7.4.1 Isopropyl Alcohol, 90 %,
7.4.2 Distilled Water, 9 %, and
7.4.3 Ammonium Hydroxide, 1 %.
NOTE 2 - Warning: Poison. Causes burns. Vapor extremely irritating. May be fatal if swallowed. Harmful if inhaled.
7.5 Stoddard Solvent, as described in Specification D235.
NOTE 3 - Warning: Combustible. Vapor harmful.
7.6 Synthetic Sea Water, prepared as described in Test Method D665.
NOTE 4 - Warning: Poison. May be fatal if swallowed.
