1. Scope
1.2 These practices are applicable to waste liquids, sludges, semi-solids, and solids. 1.3 These practices are designed and intended as a prelimi- nary or supplementary test to complement the more sophisti- cated quantitative analytical techniques that should be used to determine waste composition and compatibilities. This stan- dard offers the user the option and the ability to screen wastes for potentially hazardous reactions when the more sophisti- cated techniques are not available and the total waste compo- sition is unknown, and to screen compatibility when the composition is known. (Warning—Delayed or slow reactions of wastes may go unnoticed.) 1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.4.1 Exception—The values given in parentheses are for information only. 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 appro- priate safety, health, and environmental practices and deter- mine the applicability of regulatory limitations prior to use. For specific hazard and warning statements, see Sections 1.3, 6.1, 10, 11.2.3, 11.5.2, 16, and 23. 1.6 This international standard was developed in accor- dance with internationally recognized principles on standard- ization established in the Decision on Principles for the Development of International Standards, Guides and Recom- mendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
3. Terminology
3.1 Definitions—For definitions ofterms used in this screen- ing practice, refer to Terminology D5681. 3.2 Definitions ofTerms Specific to This Standard: 3.2.1 screening—a preliminary qualitative or semi- quantitative test, developed from classical qualitative and quantitative techniques, that is designed to efficiently give the user specific information about a waste that will aid in determining waste identification, process compatibility, and safety in handling.
4. Summary of Practices
4.1 Practice A—Representative samples of waste are added to each other. The generation of heat or violent reaction is noted. In addition, the production ofmists, fumes, dusts, gases, layering, polymerization, precipitation, emulsification or in- crease in viscosity, and other chemical or physical changes are noted. 4.2 Practice B—Reactivity of wastes is determined by adding an aliquot of a sample to an equal volume of reagent and observing any characteristic reaction, such as temperature increase, gas evolution, gelling, or polymerization. 4.3 Practice C—Water and the waste are mixed in an approximate 10 + 1 ratio to test for compatibility. A thermom- eter is used to measure heat generation when applicable. Qualitative solubility and relative apparent density are ob- served concurrently.
5. Purity of Reagents
5.1 Purity of Reagents—Reagent-grade chemicals shall be used in all tests. Unless otherwise indicated, it is intended that all reagents conform to the specifications of the Committee on Analytical Reagents of the American Chemical Society, where such specifications are available. 3 Other grades may be used provided it is first ascertained that the reagent is of sufficiently high purity to permit its use without lessening the accuracy of the determination (see Practice E200). 5.2 Purity ofWater—Unless otherwise indicated, references to water shall be understood to mean reagent water as defined by Type III of Specification D1193.
6. Sampling
6.1 Warning—Avoid inhalation of or skin contact with any hazardous waste. 6.2 Obtain representative samples of waste. If composite samples are taken, report any generation of heat, gases, or solids during compositing. If reactions are observed during compositing, then individual samples should be taken. If the waste is suspected of containing varying proportions of reac- tive compounds, take individual samples and conduct tests on each sample. 6.3 Allow all samples to stabilize to room temperature and analyze as soon as possible. 6.4 Always perform this procedure in a hood with the sash down as far as possible.
