Summary of Test Methods Summary of Practices4.1 Test Method APractice A Repres
16、entative samples of waste are added to each other. The generation of heat or violentreaction is noted. In addition, the production of mists, fumes, dusts, gases, layering, polymerization, precipitation, emulsificationor increase in viscosity and other chemical or physical changes are noted.4.2 Test
17、Method BPractice B Reactivity of wastes is determined by adding an aliquot of a sample to an equal volume ofreagent and observing any characteristic reaction, such as temperature increase, gas evolution, gelling, or polymerization.4.3 Test Method CPractice C Water and the waste are mixed in an appro
18、ximate 10 + 1 ratio to test for compatibility. Athermometer is used to measure heat generation when applicable. Qualitative solubility and relative apparent density are observedconcurrently.5. Purity of Reagents5.1 Purity of ReagentsReagent grade chemicals shall be used in all tests. Unless otherwis
19、e indicated, it is intended that allreagents conform to the specifications of the Committee on Analytical Reagents of the American Chemical Society, where suchspecifications are available.3Other grades may be used provided it is first ascertained that the reagent is of sufficiently high purityto per

Sampling6.1 WarningAvoid inhalation of or skin contact wit
21、h any hazardous waste.6.2 Obtain representative samples of waste. If composite samples are taken, report any generation of heat, gases or solids duringcompositing. If reactions are observed during compositing, then individual samples should be taken. If the waste is suspected ofcontaining varying pr
22、oportions of reactive 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.7. Quality Assurance7.1 Thermometers are
23、evaluated and verified at a frequency specified by the laboratory (see Specification E1).7.2 Care is taken to ensure that samples are representative of the total wastes involved.TEST METHOD ACOMMINGLED WASTE COMPATIBILITYPRACTICE ACOMMINGLED WASTE COMPATIBILITY8.

Procedure11.1 Determine the total quantity A of th
28、e incoming waste to be added to the storage or treatment unit.11.2 Determine the total quantity B of the waste in the storage tank or treatment unit.11.2.1 Both quantities A and B must be stated in the same units of measure; pounds or gallons are typically used.11.2.2 The waste in a tank can be esti
29、mated from the design volume of the tank. The volume of a tank truck can be determinedfrom the contents net weight and an estimate of the density. A value of 3.75 kg/L (8.34 lb/gal) can be used as an approximatedensity for a wide range of aqueous wastes.11.2.3 The total volume of A and B, upon mixin
30、g, should not exceed 300 mL. The initial volume A (150 mL) may be adjustedproportionally to accommodate total volume specification. (WarningPerform a pre-test using 1 or 2 mL of each sample toreduce the risk when mixing potentially highly reactive wastes.)11.3 Place in a 500-mL beaker 150 mL of a re
31、presentative sample from the storage tank or treatment unit.11.3.1 Measure the temperature, when applicable, of the test sample and remove the thermometer.NOTE 1High precision thermometers may be employed to provide higher sensitivity in temperature readings.11.4 Use the ratio A + B of wastes to det
32、ermine the aliquot, V, in milliliters, of incoming waste to now be added. Use thefollowing equation:V 5 V A/B! (1)where V is the volume in milliliters used in step 11.3 (150 mL), and A and B are as defined in 11.1 and 11.2 respectively.11.5 Slowly and very carefully add the aliquot V of incoming was
33、te to the test sample volume V already in the beaker.11.5.1 The recommended rate of addition is approximately 1 mL/s.11.5.2 While the addition is in progress, watch for adverse reactions. (WarningIf a reaction is observed, stop the additionimmediately and report the observation.)11.6 If after adding
34、 the aliquot V of incoming waste no adverse reaction is observed, mix well and immediately measure thetemperature.11.6.1 Compare the temperature here with the temperature measured in step 11.3.1. Record the difference, using ( + ) to indicatean increase and () to indicate a decrease in temperature (
35、see Note 1).NOTE 2Mixing the representative waste samples at equal proportions can increase the sensitivity of reactivity and may be used as a substitute or inaddition to the test based on actual proportions.11.7 Record any generation of heat or violent reaction. Record the production of any mists,
36、fumes, dust, or gases.Any layering,polymerization, precipitation, emulsification, increase in viscosity, bubbling, foaming, solidification, spattering, or other interactionof the commingled wastes must be observed and recorded.11.8 If no reaction is observed, the waste passes the compatibility test.
37、 If any reaction or temperature rise is observed, theincoming waste has failed the compatibility test and is reported.12. Precision and Bias12.1 No statement is made about either the precision or bias of this test method practice since the result merely states whetherthere is conformance to the crit

Significance and Use13.1 This test methodpractice is significant to those in the waste management industries.13.2 It is designed to screen wastes that have the potential of unde

Hazards16.1 Use triethylamine in the hood and avoid exposure.16.2 With samples that do not contain any reactive compounds, this test procedure does not present any other special hazards.However, samples that are reactive will fail this test and some reaction will result. The reaction could be se

Procedure17.1 Conduct the following procedure in a fume hood:17.
43、1.1 Place approximately 1 mL of triethylamine reagent in the cavity of a ceramic spotplate.17.1.2 Place approximately 1 mL of sample in the spotplate cavity with reagent. Immediately lower hood sash as protectionagainst violent reactions.17.1.3 Observe mixture for about 1 min and record any reaction
44、 characteristics, such as gas evolution, fuming, charring,precipitation, gelling, polymerization, or burning.17.1.4 If any reaction characteristics are observed, then material is reactive and fails this test. Material which fails this testshould not be tested using 17.2 or 17.3.17.2 Conduct the foll
45、owing procedure with special care in a fume hood:17.2.1 Add about 5 mL of reagent to a 10-mL graduated cylinder or disposable test tube.17.2.2 Carefully add 5 mL of sample to the cylinder, stopper, and invert several times or vortex to mix well. Immediatelyremove stopper, insert the thermometer, and
46、 record temperature of mixture (see Note 1).17.2.3 Continue to monitor temperature of mixture for several minutes. Observe and record any reaction characteristics, suchas temperature increase, gas evolution or gelling. Note that gas evolution may be observed as tiny bubbles that consistently riseto
47、surface (see 17.3).17.2.4 If temperature increases significantly or any reaction characteristics are observed, then material is reactive and fails thistest. Material which fails this test should not be tested using 17.3.17.3 If gas evolution is difficult to observe during 17.2, conduct the following
48、 procedure with special care in a fume hood:17.3.1 Add about 5 mL of reagent to 10-mL graduated cylinder or disposable test tube.17.3.2 Carefully add 5 mL of sample to the cylinder, stopper, and invert several times or vortex to mix well. Immediatelyremove stopper and restopper. Lower hood sash as p
49、rotection against violent reaction.17.3.3 After several minutes, carefully remove stopper and observe mixture for gas evolution. Gas evolution will be observedas immediate venting or bubbles at surface, similar to opening a carbonated drink.17.3.4 If gas evolution is observed, then material is reactive and fails this test. If no gas evolution or other signs of reaction areobserved, the material has passed the test.17.3.5 Record observations.18.
