**SW-846 Update V 1030 - 1 Revision 1**

**October 2012 METHOD 1030** 

**IGNITABILITY OF SOLIDS**

**SW-846 is not intended to be an analytical training manual. Therefore, method**  **procedures are written based on the assumption that they will be performed by analysts who are**  **formally trained in at least the basic principles o f chemical analysis and in the use of the subject**  **technology.**

**In addition, SW-846 methods, with the exception of required method use for the analysis**  **of method-defined parameters, are intended to be gu idance methods which contain general**  **information on how to perform an analytical procedu re or technique, which a laboratory can use**  **as a basic starting point for generating its own de tailed standard operating procedure (SOP),**  **either for its own general use or for a specific pr oject application. Performance data included in**  **this method are for guidance purposes only and must not be used as absolute quality control**  **(QC) acceptance criteria for purposes of laboratory QC or accreditation.** 

**1.0 SCOPE AND APPLICATION**

**1.1 This method is suitable for the determination o f the ignitability of solids and is**  **appropriate for pastes, granular materials, solids that can be cut into strips, and powdery**  **substances. Also, if it is impractical to perform this test because of the physical form of the**  **sample, generator knowledge should be used to deter mine the ignitability hazard posed by the** 

**material. The test method described here is based on the test procedure adopted by the**  **Department of Transportation (DOT) from the United Nations regulations for the international**  **transportation of dangerous goods (see Appendix E t o Part 173 of 49 CFR).** 

**1.2 This method is not required by the Federal regu lations to determine if a waste**  **passes or fails the characteristic of ignitability according to the RCRA regulatory definition at 40**  **CFR 261.21. To clarify, the test results of this m ethod cannot be used to directly classify a** 

**waste as a D001 hazardous waste, nor can the result s be used by themselves to definitively**  **classify a waste as non-hazardous. No specific tes t for ignitable solids is required by the RCRA**  **regulations, and only a waste meeting the narrative regulatory definition at 40 CFR 261.21(a)(2)**  **is an ignitable hazardous waste because it is an ig nitable solid. In addition, the test in this**  **method for a liquid may be helpful in determining w hether a liquid waste has hazardous**  **properties; however, a liquid waste is only a D001 hazardous waste if it is an oxidizer, as**  **defined at 40 CFR 261.21(a)(4), or based on its fla sh point, as defined at 40 CFR 261.21(a)(1).**  **This test method was developed to specifically illu strate the ignitability properties of materials,**  **including wastes, and its results provide relevant and useful information that may be applied to**  **knowledge of a waste in determining whether a waste meets the 40 CFR 261.21 criteria.** 

**1.3 Prior to employing this method, analysts should consult the disclaimer statement at**  **the front of the manual and the information in Chap ter Two for 1) guidance on the intended**  **flexibility in the choice of methods, apparatus, ma terials, reagents, and supplies; and 2) the**  **responsibilities of the analyst for demonstrating t hat the techniques employed are appropriate**  **for the analytes of interest, in the matrix of inte rest, and at the levels of concern.** 

**In addition, analysts and data users are advised th at, except where explicitly specified in a**  **regulation, the use of SW-846 methods is** not **mandatory in response to Federal testing requirements. The information contained in this me**  **thod is provided by the Environmental Protection Agency (EPA) as guidance to be used by t**  **he analyst and the regulated community in SW-846 Update V 1030 - 2 Revision 1** 

**October 2012 making judgments necessary to generate results that**  **meet the data quality objectives (DQOs) for the intended application.** 

**1.4 This method is restricted to use by, or under s upervision of, appropriately**  **experienced and trained personnel. Each analyst mu st demonstrate the ability to generate**  **acceptable results with this method.**

**2.0 SUMMARY OF METHOD**

**In a preliminary test, the test material is formed into an unbroken strip or powder train, 250**  **mm in length. An ignition source is applied to one end of the test material to determine whether**  **combustion will propagate along 200 mm of the strip within a specified time period. Materials**  **that propagate burning along a 200-mm strip within the specified time period are then subjected**  **to a burning rate test. Materials that do not igni te or propagate combustion as described above**  **do not require further testing. In the burning rat e test, the burning time is measured over a**  **distance of 100 mm and the rate of burning is deter mined. The test method described here is**  **based on the test procedure adopted by the Departme nt of Transportation from the United**  **Nations regulations for the international transport ation of dangerous goods and is contained in**  **Appendix E to Part 173 of 49 CFR.**

**3.0 DEFINITIONS**

**Refer to Chapter One and the manufacturer's instruc tions for definitions that may be**  **relevant to this procedure.**

**4.0 INTERFERENCES**

**4.1 In laboratory tests, the burning rate of duplic ate runs is usually repeatable to within**  **10%. However, large differences in burning rates m ay occur if experimental conditions are not**  **held constant. Variation in airflow rates, particl e size, and moisture content of the test material**  **will affect test results. Therefore, at least trip licate determinations of the burning rate should be** 

**conducted.**

**4.2 Particle size of test material can affect not o nly the burning rate, but also the**  **ignition of the material. Therefore, the particle size of the test material should be the same for**  **each test run. The particle size of the test mater ial should be reported in a simple descriptive**  **format (e.g., fine powder, sand, coarse granular).**

**4.3 Temperature of some test material (such as sulf ur powder) affects the burning rate.**  **For reproducible results, all tests should be perfo rmed at approximately the same initial**  **temperature (ambient room or laboratory temperature ).** 

**4.4 All tests must be carried out inside a fume hoo d with the test apparatus situated**  **perpendicular (90 o**  **) to the direction of airflow. Airflow parallel (0 o**  **) to the test apparatus results in non-reproducible burning rates.** 

**4.5 The rate of airflow through the fume hood affec ts the burning rate. An airflow rate**  **that is too high distorts the flame and retards its horizontal propagation. The optimum airflow**  **rate appears to be in the range of 0.7-1 meters per second.** **SW-846 Update V 1030 - 3 Revision 1**

**October 2012 4.6 Materials that are moisture sensitive (i.e., re**  **adily absorb moisture from air) should be tested as quickly as possible after removal from**  **the sample container. All materials should be tested as received by the laboratory.** 

**5.0 SAFETY**

**5.1 This method does not address all safety issues associated with its use. The**  **laboratory is responsible for maintaining a safe wo rk environment and a current awareness file**  **of OSHA regulations regarding the safe handling of the chemicals specified in this method. A**  **reference file of material safety data sheets (MSDS s) should be available to all personnel**  **involved in these analyses.**

**5.2 Prior to starting the preliminary screening tes t, all sample materials must be tested**  **to determine if that material is explosive or extre mely flammable (see WARNING below). Use a**  **very small portion of material (1 g or less) for th is test.** 

**WARNING: If the sample material is explosive or extremely**  **flammable, do not conduct this test.**

**5.3 This method could involve the combustion of hig hly flammable materials and the**  **generation of toxic fumes. All tests must be condu cted in a suitable fume hood fitted with a pull**  **down sash to prevent the escape of toxic fumes into working areas. The analyst should wear**  **appropriate protective clothing, including a labora tory jacket or apron, safety glasses, and**  **protective gloves. The laboratory should have appr opriate firefighting equipment (such as a**  **Class A fire extinguisher) readily available to ext inguish small fires.** 

**6.0 EQUIPMENT AND SUPPLIES**

**The mention of trade names or commercial products i n this manual is for illustrative**  **purposes only, and does not constitute an EPA endor sement or exclusive recommendation for**  **use. The products and instrument settings cited in SW-846 methods represent those products**  **and settings used during method development or subs equently evaluated by the Agency.**  **Glassware, reagents, supplies, equipment, and setti ngs other than those listed in this manual**  **may be employed provided that method performance ap propriate for the intended application** 

**has been demonstrated and documented.**

**This section does not list common laboratory glassw are (e.g., beakers and flasks) that**  **might be used.**

**6.1 Low-heat conducting, non-combustible, imperviou s ceramic tile or equivalent**  **material, an approximate dimension of 25 cm x 25 cm x 2.5 cm (the tile must be at least 25 cm**  **in length to support a 250-mm test sample).**

**6.2 High temperature marker or equivalent marking d evice for marking ceramic plates.** 

**6.3 Powder train mold (see Figure 1) for molding po wdered and granular materials for** 

**the burn rate test. The material of construction c an be aluminum, brass, stainless steel, or**  **plastic. The mold is 250 mm in length and has a tr iangular cross-section, with a width of 20**  **mm, and a depth of 10 mm as measured from the botto m of the triangular opening to where the**  **sides meet. On both sides of the mold, in the long itudinal direction, two sheets are mounted as**  **lateral limitations which extend 2 mm beyond the up per edge of the triangular cross-section.** **SW-846 Update V 1030 - 4 Revision 1**

**October 2012 This device can be fabricated by most machine shops**  **. The complete burn rate apparatus is available from: Associated Design and Manufacturin**  **g Co., Lorton, Virginia, 22079.**

**6.4 A Bunsen (propane gas and air) burner with a mi nimum diameter of 5 mm capable**  **of attaining a temperature of at least 1,000 o**  **C.**

**6.5 Stop watch.**

**6.6 Thermocouple to measure the temperature of the gas flame.** 

**6.7 Thermometer to measure initial temperature of m aterial (i.e., room temperature).** 

**6.8 Anemometer to measure airflow in the fume hood.**

**7.0 REAGENTS AND STANDARDS**

**No special reagents or standards are required to co nduct this test.** 

**8.0 SAMPLE COLLECTION, PRESERVATION, AND STORAGE**

**8.1 Samples should be tested on an as-received basi s unless requested otherwise.**  **No sample preservation is required, but sample cont ainers should be completely filled and**  **tightly sealed to preserve sample integrity.**

**8.2 Samples should be tested as soon as possible af ter removal from the sample**  **container (i.e., samples should not be allowed to d ry or absorb moisture for excessive periods or**  **to lose volatiles). Samples that are chilled or co oled upon receipt to the laboratory should be**  **allowed to equilibrate to the ambient laboratory te mperature in the sample container.** 

**9.0 QUALITY CONTROL**

**9.1 Refer to Chapter One for additional guidance on quality assurance (QA) and**  **quality control (QC) protocols. When inconsistenci es exist between QC guidelines, method**  **specific QC criteria take precedence over both tech nique specific criteria and Chapter One**  **criteria; technique specific QC criteria take prece dence over Chapter One criteria. Any effort**  **involving the collection of analytical data should include development of a structured and**  **systematic planning document, such as a Quality Ass urance Project Plan (QAPP) or a Sampling**  **and Analysis Plan (SAP), which translates project o bjectives and specifications into directions**  **for those implementing the project and assessing th e results.** 

**Each laboratory should maintain a formal quality as surance program. The laboratory**  **should also maintain records to document the qualit y of the data generated. Development of in**  **house QC limits for each method is encouraged. Use of instrument specific QC limits is**  **encouraged, provided such limits will generate data appropriate for use in the intended**  **application. All data sheets and quality control d ata should be maintained for reference or**  **inspection.**

**9.2 All tests must be performed on a clean ceramic plate at room temperature.** **SW-846 Update V 1030 - 5 Revision 1**

**October 2012 9.3 All replicate runs must be at the same initial**  **temperature (ambient laboratory temperature).** 

**9.4 All replicate tests must be run at approximatel y the same airflow through the fume** 

**hood.**

**9.5 Only materials of the same particle size distri bution should be used for all replicate** 

**tests.**

**9.6 The burn rate test must be conducted in triplic ate if the preliminary screening test is**  **positive. Any burn rate for non-metallic samples t hat exceeds 2.2 mm/sec (or a burn time of**  **less than 45 seconds for 100 mm) is considered to h ave a positive result. For metals, a burn**  **rate of more than 0.17 mm/sec (or burn time of less than 10 minutes for 100 mm) is considered**  **to have a positive result.**

**10.0 CALIBRATION AND STANDARDIZATION**

**There are no calibration or standardization steps d irectly associated with this procedure.**  **See the equipment manufacturer's instructions for t he calibration of certain equipment used in**  **this method (e.g., the thermocouple).**

**11.0 PROCEDURE**

**WARNING : Prior to starting the preliminary screening test,**  **all sample materials must be tested**

**to determine if that material is explosive or extre mely flammable. Use a very small**  **portion of material (1 g or less). If the sample m aterial is explosive or extremely**  **flammable, do not conduct this test.**

**11.1 Preliminary screening test**

**11.1.1 The preliminary screening test for ignitabil ity is conducted on all waste**  **materials. On a clean, impervious ceramic tile (Se c. 6.1), clearly mark a 250 mm long test**  **path. Make another mark at exactly 200 mm from the start of the sample path.** 

**11.1.2 Prepare the test material in its "as receive d" form by forming an unbroken**  **strip or powder train of sample 250 mm long by 20 m m wide by 10 mm high on the** 

**ceramic tile. Use the mold to form the material as described in Sec. 11.2.3.1, if**  **appropriate.**

**11.1.3 Place the ceramic tile with the loaded sampl e in a fume hood about 20 cm**  **(~8 inches) from the front of the hood and in an ar ea of laminar airflow. Position the**  **sample perpendicular to the airflow (See Figure 2). The airflow across the perpendicular**  **axis of the sample should be sufficient to prevent fumes from escaping into the laboratory**  **and should not be varied during the test. The air velocity should be approximately 0.7**  **meters/second. Measure the air velocity with an an emometer.** 

**11.1.4 Light the Bunsen burner and adjust the heigh t of the flame (6.5 to 7.5 cm)**  **by adjusting the propane gas and air flows. Measur e the temperature of the flame (tip of**  **the flame) by a thermocouple. The temperature of t he flame must be at least 1000**  ° **C. SW-846 Update V 1030 - 6 Revision 1** 

**October 2012 11.1.5 Apply the tip of the flame to one end of the**  **sample strip. The test period will depend on the sample matrix (whether non-metal**  **lic or metallic) as described below in**

**Sec. 11.1.5.1 and 11.1.5.2.**

**11.1.5.1 If the waste is non-metallic, hold the fla me tip on the sample**  **strip until the sample ignites or for a maximum of 2 minutes. If combustion occurs,**  **begin timing with a stop watch and note whether the combustion propagates up to**  **the 200 mm mark within the 2 minute test period.**

**11.1.5.2 If the waste is a metal or metal alloy pow der, hold the flame tip**  **on the sample strip until the sample ignites or for a maximum of 5 minutes. If**  **combustion occurs, begin timing with a stop watch a nd note whether the**  **combustion propagates up to the 200-mm mark within the 20 minute test period.** 

**11.1.6 If the waste does not ignite and propagate c ombustion either by burning**  **with open flame or by smoldering along the 200-mm s ample strip within the 2 minute test**  **period (or 20 minute test period for metal powders) , the waste is not considered flammable**  **and no further testing is required. If the waste p ropagates burning of 200 mm of the test**  **strip within the 2 minute test period (20 minute te st period for metals), the material must be**  **evaluated by the burning rate test (proceed to Sec. 11.2).** 

**11.2 Burning rate test**

**11.2.1 The preparation of the test sample for the b urning rate test will depend on**  **the physical characteristics of the waste. Wastes that exist in a powdered or granular**  **state are molded in a powder train mold as shown in Figure 1. Pasty materials are formed**  **into a rope that is 250 mm in length with a cross-s ection of 1 cm**  **2 . All tests for the burn**  **rate test are performed on clean, ambient temperatu re, ceramic plates.** 

**11.2.2 On a clean, impervious ceramic tile (Sec. 6. 2), clearly mark a 250-mm**  **long test path. Make two additional timing marks a t 80 mm and 180 mm from the start of**  **the sample path. The distance between the two mark s (100 mm) will be used to calculate** 

**the rate of burn in Sec. 12.0.**

**11.2.3 Sample preparation based on physical charact eristics** 

**11.2.3.1 Powder or granular material -- Tighten the side plates on the**  **mold. Place the mold on the base plate. Pour the material to fill the triangular**  **cross section of the mold loosely. Drop the unit f rom a height of 2 cm onto a solid**  **surface three times to settle the powder. Remove t he side supports. Lift the mold**  **off the base plate. Place a clean ceramic test pla te with the appropriate timing**  **marks (Sec. 11.2.2) face down on top of the mold. Invert the setup and remove the** 

**mold.**

**11.2.3.2 Pasty wastes - Spread the waste on a marke d ceramic tile**  **(Sec. 11.2.2) in the form of a rope 250 mm in lengt h with a cross-section of 1 cm**  **2**

**.**

**11.2.4 Place the ceramic tile with the loaded sampl e prepared in Sec. 11.2.3 in a**  **fume hood about 20 cm (~8 in) from the front of the hood and in an area of laminar airflow.**  **Position the sample perpendicular to the airflow (S ee Figure 2). The airflow across the**  **perpendicular axis of the sample should be sufficie nt to prevent fumes from escaping into**  **the laboratory and should not be varied during the test. The air velocity should be** **SW-846 Update V 1030 - 7 Revision 1**

**October 2012 approximately in the range of 0.7-1 meters/second.**  **Measure the air velocity with an**

**anemometer.**

**11.2.5 Light the Bunsen burner and adjust the heigh t of the flame (6.5 to 7.5 cm)**  **by adjusting the propane gas and air flows. Measur e the temperature of the flame (tip of**  **the flame) by a thermocouple. The temperature of t he flame must be at least 1000**  ° **C.**

**11.2.6 Apply the tip of the flame to one end of the sample strip to ignite the test**  **strip as described in Sec. 11.1.5.1 or 11.1.5.2 (ba sed on whether the sample is non**  **metallic or metallic).**

**11.2.7 When the test strip or powder train has burn ed up to the 80-mm time**  **marker, begin timing the rate of combustion with a stop watch. Stop the timer when the**  **burned strip reaches the 180-mm time marker. Recor d the amount of time (in sec)**  **required to burn the 100-mm test strip.**

**12.0 DATA ANALYSIS AND CALCULATIONS**

**Calculate the rate of burning by dividing the lengt h of the burn test strip (100 mm) by the**  **total time (sec). Results of the burn rate test sh ould be reported in mm/sec. Wastes that have a**  **rate of burning of more than 2.2 mm/sec (or burn ti me of less than 45 sec for 100 mm) are**  **considered to have a positive result for ignitabili ty according to DOT regulations. For metals,**  **this time is 10 minutes or less for 100 mm (or a bu rn rate of more than 0.17 mm/sec). The**  **following format may be used to document the data.**

**October 2012 13.0 METHOD PERFORMANCE** 

**13.1 Performance data and related information are p rovided in SW-846 methods only as**  **examples and guidance. The data does not represent required performance criteria for users of**  **the methods. Instead, performance criteria should be developed on a project-specific basis,**  **and the laboratory should establish in-house QC per formance criteria for the application of this** 

**method. Performance data must not be used as absol ute QC acceptance criteria for laboratory** 

**QC or accreditation.**

**13.2 An independent laboratory validation was condu cted on the robustness of the burn**  **rate test procedure. The materials selected for th is evaluation included:** 

**1. A 50/50 mixture of metallic silicon and lead d ioxide (PbO**  **2 )** 

**2. Excelsior 3. Dextrin (yellow powder)**  **4. Sulfur (fine yellow powder) 5. Aluminum metal (coarse)**  **6. Magnesium metal (coarse) 7. Polyethylene high density (granular)**  **8. Polyethylene low density (fluffy white powder) 9. Scott fertilizer (32-3-10:N-P-K)**  **10. JP-4 contaminated soil (approximately 5000 ppm )** 

**Of these materials, the 50/50 mixture of metallic silicon and lead dioxide (PbO**  **2 ), elemental**  **sulfur, and excelsior gave a positive ignitability result under the conditions of the test. The**  **remaining materials gave negative (nonflammable) re sults under the conditions of the test.**  **Several test variables including: ignition source, ambient temperature, and apparatus**  **orientation, were studied using these materials. P artial results of this study are summarized in**  **Table 1. These data are provided for guidance purp oses only.** 

**13.3 In another evaluation of the DOT burn rate tes t, potentially ignitable finishing**  **wastes from the furniture industry were collected a nd tested for burning rates. Each waste was**  **tested in triplicate to establish a mean value for the burning rate. The results for the flammable**  **wastes are summarized in Table 2. These data are p rovided for guidance purposes only.** 

**13.4 In order to evaluate the ruggedness of the DOT burn rate test, select ignitable**  **finishing wastes were split and tested by a state l aboratory and an independent contract**  **laboratory. The results of this comparison are sum marized in Table 3. These data are provided**  **for guidance purposes only.**

**14.0 POLLUTION PREVENTION**

**14.1 Pollution prevention encompasses any technique that reduces or eliminates the**  **quantity and/or toxicity of waste at the point of g eneration. Numerous opportunities for pollution**  **prevention exist in laboratory operations. The EPA has established a preferred hierarchy of**  **environmental management techniques that places pol lution prevention as the management**  **option of first choice. Whenever feasible, laborat ory personnel should use pollution prevention**  **techniques to address their waste generation. When wastes cannot be feasibly reduced at the**  **source, the Agency recommends recycling as the next best option.** **SW-846 Update V 1030 - 9 Revision 1**

**15.0 WASTE MANAGEMENT**

**The Environmental Protection Agency requires that l aboratory waste management**  **practices be conducted consistent with all applicab le rules and regulations. Laboratories are**  **urged to protect air, water, and land by minimizing and controlling all releases from hoods and**  **bench operations, complying with the letter and spi rit of any sewer discharge permits and**  **regulations, and by complying with all solid and ha zardous waste regulations, particularly the**  **hazardous waste identification rules and land dispo sal restrictions.
