Summary of Test Method4.1 The stability and miscibility of a waste material areobserved when the waste is mixed with various media.5. Significance and Use5.1 This test method will identify waste materials that arepotent

9、ially unstable when they come in contact with othermaterials at a waste treatment or disposal site.5.2 This test method will serve to determine the miscibilityof waste materials with various media, including other wastes.5.3 This test method may not be applicable to all wastes.The appropriateness of

10、 these tests depends upon the proposedmanagement of the waste.5.4 Since the initiation of some chemical reactions are slowto take place, the user may wish to establish reagent-to-wastecontact times prior to observing the mixes for any reactions.6.

Reagents7.1 Purity of WaterThe deionized water used to preparethe aqueous test solutions should conform to the conductivityspecifications ofAST

15、M Type II water as found in SpecificationD1193.7.2 Hydrochloric Acid (HCl) Test Solution, carefully mix100 g of reagent grade hydrochloric acid (;36 %) with 900 gof deionized water.7.3 Sodium Hydroxide (NaOH) Test Solution, carefully mix200 g of reagent grade sodium hydroxide solution (;50 %)with 80

18、ds.9. Procedure9.1 Refer to the samples label and respective chemicalcomposition data to determine if there is any waste componentlisted that could react with the agents or materials selected fortesting.9.2 Air Stability:9.2.1 Open the cap of the sample container very slowly, andremove the cap slowl

19、y by sliding it across the top of the samplecontainer.9.2.2 If any evidence of fuming is observed when thecontainer is first opened, close the container immediately andrefer to the samples respective chemical composition data todetermine if there is any waste component listed that could bereactive i

20、n air. If no air reactive components are identified, thencarefully open the container.9.2.3 Using a glass, plastic spatula, or disposable dropper,remove a small portion of the sample and place it on a watchglass to observe any reaction of the waste in air. Note anyreaction. If the waste sample is ai

21、r reactive, do not proceedwith any of the following steps.9.3 Water Stability:9.3.1 Mix liquid waste sample thoroughly, and place a10-mL aliquot of the sample in a 40-mL plastic cup. For drywaste or sludges, add enough sample to fill the cup to the10-mL mark.9.3.2 Pour 10-mL of water slowly and care

22、fully over thesample and observe any reaction. If no reaction is observedimmediately, then mix the sample and water and note anyreaction. Also estimate the volume percent solubility of thesample in water. If the waste appears to be water reactive, it issuggested that the appropriateness of the follo

For dry waste orsludges, fill to the 10-mL mark.9.4.2 Slowly and carefully add 10-mL of the HCl testsolution or up to 10-mL until a reaction is observed.

24、 If noreaction is observed after the addition of 10-mL, then carefullymix the HCl solution with the sample until it is evenly mixed.Note any reaction that occurs. Also estimate the volumepercent solubility of the sample in the acid.9.5 Stability with Base:9.5.1 Take a 10-mL aliquot of the well mixed

25、 liquid wastesample and place it in a 40-mL plastic cup. For dry waste orsludges, fill to the 10-mL mark.9.5.2 Slowly and carefully add 10-mL of the NaOH testsolution or up to 10-mL until a reaction is observed. If noreaction is observed after the addition of 10-mL, then carefullymix the NaOH soluti

26、on with the sample until it is evenlymixed. Note any reaction that occurs.Also estimate the volumepercent solubility of the sample in base.9.6 Stability with Organics:9.6.1 For waste material that may be mixed with otherwastes for treatment and disposal, take a 10-mL aliquot of thewell mixed liquid

27、waste sample and place it in a 40-mL plasticcup. For dry waste or sludges fill to the 10-mL mark.9.6.2 Slowly and carefully add 10-mL of oil/solvent mixtureor up to 10-mL until a reaction is observed. If no reaction isobserved after the addition of 10-mL, then carefully mix theoil/solvent with the s

28、ample until it is evenly mixed. Note anyreaction that occurs. Also estimate the volume percent solubil-ity of the sample with organics.9.7 Stability with Other Waste Materials or Solid Media:9.7.1 Place a 10-mL aliquot of the well mixed liquid samplein a 40-mL plastic cup. For dry waste or sludge, f

29、ill to the10-mL mark.9.7.2 Carefully and slowly add 10-mL of the other wastematerial or solid media or up to 10-mL until a reaction isobserved. If no reaction is observed after the addition of the10-mL, then carefully mix the contents of the plastic cup untilevenly mixed. Note any reaction that occu

30、rs. Also note thevolume percent solubility of the waste sample with the otherwaste material, if applicable.10. Interpretation of Results10.1 If the waste material reacts with any of the test mediaevaluated, resulting in the evolution of heat or the vigorousevolution of gases, then the waste will be

31、termed unstable withthat respective media.10.2 The solubility of the waste material observed whenmixed with the various liquid media can be an indication of themiscibility of the waste in those media.D5232 13211. Precision and Bias11.1 PrecisionIt is not practicable to specify the precisionof the pr
