Got a question about the generation, identification, management, transportation, and disposal of hazardous waste, universal waste, used oil, or non-hazardous waste?

Q:  What is the paint filter test?

A:  The paint filter test is test method specified by the USEPA (USEPA Method 9095A) used to determine the presence of free liquids in a representative sample of waste.  A predetermined amount of material is placed in a paint filter, any portion of the material that passes through the filter in a five-minute test period is identified as free liquids.  The method is used to determine compliance with 40 CFR 264.314 and 265.314.  However, the presence of free liquids is critical to a generators hazardous waste determination as well; especially for the characteristics of Ignitability (D001) and Corrosivity (D002).
