The presence of inorganic chlorides and sulfates in oil in contact with metal surfaces in electrical equipment can result in corrosion of transformer components. The deterioration of metal surfaces is dependent upon the quantity of the corrosive agent and the operating environment. Although not quantitative, this test method is a means for recognizing the potential for such a hazard.1.1 This test method describes the qualitative determination of inorganic chlorides and sulfates in electrical insulating oils. Note 1 - It should be pointed out that if the strong acids, hydrochloric and sulfuric, are present, they will give positive results for chlorides and sulfates, respectively.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.

This practice is intended for inorganic process wastes that can be used as replacements for natural material such as soil or rock suitable for construction applications. Selection of appropriate and feasible fill materials and selection of applicable materials, tests, and specifications to facilitate construction and environmental protection are the responsibility of the design engineer. This practice is intended to encourage wider utilization of waste materials.1.1 This guide provides guidance for use of selected process wastes as structural fills by listing representative test methods for predicting and evaluating those physical characteristics of waste that are related to the integrity of fills and to protection of ground and surface waters. 1.2 Table 1 lists references which provide engineering practices and test procedures that may be applied to process waste for use as structural fill. 1.3 This guide includes approaches for the environmental assessment of process wastes prior to application.

Anionic surfactants, such as those listed in 1.1, commonly are used in detergent formulations. Their acceptability for use depends on their purity. Sulfate content, as measured by this test method, can be used to estimate the purity of an anionic surfactant under test.1.1 This test method describes a potentiometric titration procedure for determining the inorganic sulfate content of surfactants. It is intended for the analysis of -olefin sulfonates, alkane sulfonates, alcohol sulfates, alcohol ether sulfates, alkylbenzenesulfonates, and the like.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. Material Safety Data Sheets are available for reagents and materials. Review them for hazards prior to usage.

1.1 This practice consists of a procedure for decomposition of wood as an initial step for analysis for the constituents arsenic, chromium, copper, phosphate, and zinc, all of which may then be analyzed in accordance with Test Methods D 1326, D 1627, D 1628 and D 5584.1.2 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. Specific precautionary statements are given in Section 7.
