EPA Method 1040:

Aliquots of the waste sample are mixed thoroughly with fibrous cellulose in both 1:1 and 4:1 weight-to-weight ratios. An aliquot of the waste:cellulose mixture is formed into a truncated conical pile on a cool, impervious surface by means of a glass funnel. The sample is ignited by means of an electrically-heated wire inserted into the base of the pile. The burning time (in seconds) of each waste mixture is measured under standard conditions and recorded. The test is repeated five times for each waste:cellulose ratio mixture.

This method can be used to evaluate the relative oxidizing hazard posed by a solid waste. The method is based on a "conical pile-type burning test method" adapted from the United Nations regulations and classification procedures for the international transportation of dangerous goods.
