5.1 Identification of a brackish water, seawater, or brine is determined by comparison of the concentrations of their dissolved constituents. The results are used to evaluate the water as a possible pollutant, or as a commercial source of a valuable constituent such as lithium.1.1 This test method covers the determination of soluble lithium, potassium, and sodium ions in brackish water, seawater, and brines by atomic absorption spectrophotometry.21.2 Samples containing from 0.1 to 70 000 mg/L of lithium, potassium, and sodium may be analyzed by this test method.1.3 This test method has been used successfully with artificial brine samples. It is the user's responsibility to ensure the validity of this test method for waters of untested matrices.1.4 The values stated in SI units are to be regarded as standard. The values given in parentheses are mathematical conversion to inch-pound units that are provided for information only and are not considered standard.1.5 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.1.6 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.

A knowledge of the inorganic constituent composition in a waste is often required for the selection of appropriate waste disposal practices. Solid waste may exist in a variety of forms and contain a range of organic and inorganic constituents. This practice describes a drying and ashing step that may be applied to remove moisture and volatile and nonvolatile organic constituents prior to determining nonvolatile metals. Generation of a dry ash concentrates the inorganic constituents of interest and makes the LiBO2 fusion feasible for a greater variety of waste samples. Acidification of the LiBO2 fusion mix results in a solution amenable to inductively coupled plasma (ICP) or atomic absorption spectrometry (AAS) analysis.1.1 This practice covers the drying, ashing, and solubilization of solid waste using a lithium metaborate (LiBO2) fusion for the subsequent determination of inorganic constituents by argon plasma emission spectroscopy or atomic absorption spectroscopy.1.2 The following elements may be solubilized by this practice:aluminum chromium siliconbarium iron titaniumcadmium magnesium vanadiumcalcium manganese zinccopper nickel 1.3 This practice has been used successfully with a bauxite ore and a neutralized metal treatment sludge. The practice may be applicable to other elements not listed above. Some metals, such as cadmium and zinc, may volatilize from some samples during the drying, ashing, or fusion steps. The analyst is responsible for determining whether the practice is applicable to the solid waste being tested.1.4 This practice is intended for the solubilization of nonvolatile inorganic constituents in solid waste. The LiBO2 fusion is appropriate for a silicate matrix or acid resistant samples.1.5 This standard does not purport to address all of the safety problems 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. For specific hazard statements see Section 7.

Lubricating greases can contain the lithium soap of hydroxy stearic acid or the sodium soap of various fatty acids as thickeners. The determination of total lithium or total sodium is a measure of the amount of thickener in the grease.1.1 This test method covers determination of the lithium and sodium content of lubricating greases by means of a flame photometer.1.2 A multi-element analysis method for greases, which includes the measurement of lithium and sodium concentrations using inductively couple plasma-atomic emission spectroscopy (ICP-AES), is available in Test Method D 7303.1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.The preferred units are mass %.1.4 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.

1.1 The purpose of this guide is to provide standard methods for the safe use of Li-ion batteries onboard vessels. The guidelines in this document were developed primarily for larger Li-ion marine battery installations, such as for propulsion or ships service electrical power. The guidelines may not be appropriate for smaller battery packages such as those for computers, packaged uninterruptible power supply (UPS) units, and tools.1.2 Advances in energy storage technology have enabled new possibilities in shipboard power systems. Currently, lead acid batteries comprise the vast majority of shipboard power storage installations due to their low cost and predictable performance. Li-ion batteries are very energy dense, are becoming less expensive and make all-electric or hybrid-electric power systems possible on some types of vessels. There are many unique safety concerns related to Li-ion battery installations which are addressed here. Battery technology is rapidly developing and users should be aware of additional safety practices unique to each particular battery chemistry.1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.1.4 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.1.5 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.
