This method is used to determine the presence of free liquids in a representative sample of waste and used to determine compliance with 40 CFR 264.314 and 265.314. A 100mL or 100g representative sample is placed in a paint filter. If any portion of the material passes through and drops from the filter within the 5-min test period, the material is deemed to contain free liquids.
Particles to be tested should be smaller than 1cm which means it is capable fo passing through a 9.5mm standard sieve.
If it is not possible to get a representative sample size using 100mL or 100g then larger sizes can be used for testing, however, the sample should be divided into 100mL or 100g portions and each portion tested separately. if any portion contains free liquids then the entire samples is considered to have free liquids.
Temperautre can affect the test results if the test is performed below the freezing point of any liquid in the sample. The test must be performed above the freezing point and can, but isn't required to, exceed room temperature of 25°C.

* The analytes and detection limits listed for each method represent the typical detection limits and analytes reported for that particular method. Keep in mind that analyte lists may vary from laboratory to laboratory. Detection limits may also vary from lab to lab and are dependent upon the sample size, matrix, and any interferences that may be present in the sample.
