Standard Test Method for Determining the Stability and Miscibility of a Solid, Semi-Solid, or Liquid Waste Material

Standard Test Method for Determining the Stability and Miscibility of a Solid, Semi-Solid, or Liquid Waste Material

SIGNIFICANCE AND USE
This test method will identify waste materials that are potentially unstable when they come in contact with other materials at a waste treatment or disposal site.
This test method will serve to determine the miscibility of waste materials with various media, including other wastes.
This test method may not be applicable to all wastes. The appropriateness of these tests depends upon the proposed management of the waste.
Since the initiation of some chemical reactions are slow to take place, the user may wish to establish reagent-to-waste contact times prior to observing the mixes for any reactions.
SCOPE
1.1 This test method is designed to determine whether a waste material reacts when it is mixed with air, water, strong acid, strong base, an oil/solvent mixture, other waste mixtures, or solid media such as a geological formation or solidification agents.
1.2 The miscibility of the waste material with the above media can also be defined.
Note 1—The following ASTM standards provide supplemental information: Test Methods D 4978, D 4979, D 4980, D 4981, D 4982, D 5049, D 5057, and D 5058.
1.3 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.

Standard Test Method for Determining the Bulk Density of Solid Waste Fractions

SIGNIFICANCE AND USE
5.1 This test method describes a physical property of solid waste in processing facilities, a property that characterizes the solid waste streams and hence the operation of resource recovery separators and processors.  
5.2 The bulk density is an important property for the design of materials handling equipment, separators, and processors.  
5.3 In this test method, bulk density is not considered an absolute material property as is the density of individual particles of a material. The measured bulk density here depends on the size of the container, the moisture content of the “as tested” material, and how the material is loaded into the container. For example, the bulk density of material placed loosely in a container will be less than that of material tamped into a container. Also, some materials placed loosely in a container will settle with time due to its own weight; thus, its bulk density will increase. As written, the “as tested” waste sample may or may not be dried prior to testing, so that calculated bulk density includes the moisture associated with the “as tested” material.
SCOPE
1.1 This test method may be used to determine the bulk density of various fractions from the resource recovery processing of municipal solid waste. It is intended as a means of characterizing such fractions and for providing data useful to designers of solid waste processing plants.  
1.2 The values stated in SI units are to be regarded as standard. The values given in parentheses are for information only.  
1.3 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.  
1.4 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.

Standard Test Method for Laboratory Weathering of Solid Materials Using a Humidity Cell

SIGNIFICANCE AND USE
5.1 The laboratory weathering procedure will generate data that can be used to: (1) determine whether a solid material will produce an acidic, alkaline, or neutral effluent, (2) identify solutes in the effluent that represent dissolved weathering products formed during a specified period of time, (3) determine the mass of solute release, and (4) determine the rate at which solutes are released (from the solids into the effluent) under the closely controlled conditions of the test.  
5.2 Data generated by the laboratory weathering procedure can be used to address the following objectives: (1) determine the variation of drainage quality as a function of compositional variations (for example, iron sulfide and calcium+magnesium carbonate contents) within individual mine-rock lithologies, (2) determine the amount of acid that can be neutralized by the sample while maintaining drainage pH ≥6.0 under the conditions of the test, (3) estimate mine-rock weathering rates to aid in predicting the environmental behavior of mine rock, and (4) determine mine-rock weathering rates to aid in experimental design of site-specific kinetic tests.  
5.3 The laboratory weathering procedure provides conditions conducive to oxidation of solid material constituents and enhances the transport of weathering reaction products contained in the resulting weekly effluent. This is accomplished by controlling the exposure of the solid material sample to such environmental parameters as reaction environment temperature and application rate of water and oxygen.  
5.4 Because efficient removal of reaction products is vital to track mineral dissolution rates during the procedure, laboratory leach volumes are large per unit mass of rock to promote the rinsing of weathering reaction products from the mine-rock sample. A comparison of laboratory kinetic tests with field tests has shown that more reaction products from mineral dissolution are consistently released per unit weight and unit time in laborat...
SCOPE
1.1 This kinetic test method covers a laboratory weathering procedure that (1) enhances reaction-product transport in the aqueous leach of a solid material sample of specified mass, and (2) measures rates of weathering-product mass release. Soluble weathering products are mobilized by a fixed-volume aqueous leach that is performed and collected weekly. Leachate samples are analyzed for pH, alkalinity/acidity, specific conductance, sulfate, and other selected analytes.  
1.1.1 This test method is intended for use to meet kinetic testing regulatory requirements for mining waste rock and ores sized to pass a 6.3-mm (0.25-in.) Tyler screen.  
1.1.2 Interlaboratory testing of this method has been confined to mine waste rock. Application of this test method to metallurgical processing waste (for example, mill tailings) is outside the scope of the test method.  
1.2 This test method is a modification of a laboratory weathering procedure developed originally for mining wastes (1-3).2 However, it may have useful application wherever gaseous oxidation coupled with aqueous leaching are important mechanisms for contaminant mobility.  
1.3 This test method calls for the weekly leaching of a well-characterized solid material sample (weighing at least 1000 g) with water of specified purity, and the collection and chemical characterization of the resulting leachate. Test duration is determined by the user’s objectives of the test. See Guide D8187.3  
1.4 As described, this test method may not be suitable for some materials containing plastics, polymers, or refined metals. These materials may be resistant to traditional particle size reduction methods.  
1.5 Additionally, this test method has not been tested for applicability to organic substances and volatile matter.  
1.6 This test method is not intended to provide leachates that are identical to the actual leachate produced from a solid material in the field or to produce leach...

Standard Guide for Interpretation of Standard Humidity Cell Test Results

SIGNIFICANCE AND USE
4.1 Use of HCT Data and Testing Objectives—The laboratory weathering test method (D5744) generates data that can be used to:  
4.1.1 Determine whether a solid material will produce an acidic, alkaline, or neutral effluent;  
4.1.2 Identify solutes in the effluent that represent dissolved weathering products formed during a specified period of time, and inform the user of their potential to produce environmental impacts at a mining or metallurgical processing site under proposed operating conditions;  
4.1.3 Determine the mass of solute release; and  
4.1.4 Determine the rate at which solutes are released (from the solids into the effluent) under the closely controlled conditions of the test for comparison to other materials.  
4.1.5 These approaches are based on the existence of detailed mineralogical work and static tests that provide a basis for interpreting HCT results.  
4.1.6 Detailed mineralogical work might lead a reviewer to suspect either acid neutralization potential (ANP) or acid generation potential (AGP) minerals have questionable availability, which would be a significant factor in interpreting HCT results and decisions concerning test duration.  
4.2 Interpretation of data generated by the laboratory weathering procedure can be used to address the following objectives:  
4.2.1 Determine the variation of drainage quality as a function of compositional variations (for example, iron sulfide and calcium plus magnesium carbonate contents) within individual mine rock lithologies;  
4.2.2 Determine the amount of acid that can be neutralized by the sample while maintaining a drainage pH of ≥6.0 under the conditions of the test;  
4.2.3 Estimate mine rock weathering rates to aid in predicting the environmental behavior of mine rock; and  
4.2.4 Determine mine rock weathering rates to aid in experimental design of site-specific kinetic tests.  
4.3 Interpretation Approaches—Guides A, B, and C are intended as examples of what to consider in developin...
SCOPE
1.1 This kinetic test guide covers interpretation and cooperative management of a standard laboratory weathering procedure, Test Method D5744. The guide suggests strategies for analysis and interpretation of data produced by Test Method D5744 on mining waste rock, metallurgical processing wastes, and ores.  
1.1.1 Cooperative management of the testing involves agreement of stakeholders in defining the objectives of the testing, analytical requirements, planning the initial estimate of duration of the testing, and discussion of the results at decision points to determine if the testing period needs to be extended and the disposition of the residues.  
1.2 The humidity cell test (HCT) enhances reaction product transport in the aqueous leach of a solid material sample of specified mass. Standard conditions allow comparison of the relative reactivity of materials during interpretation of results.  
1.3 The HCT measures rates of weathering product mass release. Soluble weathering products are mobilized by a fixed-volume aqueous leach that is performed and collected weekly. Leachate samples are analyzed for pH, alkalinity/acidity, specific conductance, sulfates, and other selected analytes which may be regulated in the environmental drainage at a particular mining or metallurgical processing site.

Standard Practice for Nitric Acid Digestion of Solid Waste

SIGNIFICANCE AND USE
5.1 A knowledge of the inorganic composition of 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 digestion procedure which dissolves many of the toxic inorganic constituents and produces a solution suitable for determination of total recoverable contents by such techniques as atomic absorption spectroscopy, atomic emission spectroscopy, and so forth. The relatively large sample size aids representative sampling of heterogenous wastes. The relatively small dilution factor allows lower detection limits than most other sample digestion methods. Volatile metals, such as lead and mercury, are not lost during this digestion procedure, however organo-lead and organo-mercury may not be completely digested. Hydride-forming elements, such as arsenic and selenium, may be partially lost. Samples with total metal contents greater than 5 % may give low results. The analyst is responsible for determining whether this practice is applicable to the solid waste being tested.
SCOPE
1.1 This practice describes the partial digestion of solid waste using nitric acid for the subsequent determination of the total recoverable content of inorganic constituents.  
1.2 This practice is to be used when the concentrations of total recoverable elements are to be determined from a waste sample. Total recoverable elements are often not equivalent to total elemental content, because of the solubility of the speciated forms of the element in the sample matrix. Recovery from refractory sample matrices, such as soils, is usually significantly less than total concentrations of the elements present.  
Note 1: This practice has been used successfully for oily sludges and a municipal digested sludge standard [Environmental Protection Agency (EPA) Sample No. 397]. The practice may be applicable to some elements not listed above, such as arsenic, barium, selenium, cobalt, magnesium, and calcium. Refractory elements such as silicon, silver, and titanium, as well as organo-mercury, are not solubilized by this practice.
