Sec. 261.21  Characteristic of ignitability.

    (a) A solid waste exhibits the characteristic of ignitability if a 
representative sample of the waste has any of the following properties:
    (1) It is a liquid, other than an aqueous solution containing less 
than 24 percent alcohol by volume and has flash point less than 60 C 
(140 F), as determined by a Pensky-Martens Closed Cup Tester, using the 
test method specified in ASTM Standard D-93-79 or D-93-80 (incorporated 
by reference, see Sec. 260.11), or a Setaflash Closed Cup Tester, using the

as determined by an equivalent test method approved by the Administrator 
under procedures set forth in Secs. 260.20 and 260.21.
    (2) It is not a liquid and is capable, under standard temperature 
and pressure, of causing fire through friction, absorption of moisture 
or spontaneous chemical changes and, when ignited, burns so vigorously 
and persistently that it creates a hazard.
    (3) It is an ignitable compressed gas as defined in 49 CFR 173.300 
and as determined by the test methods described in that regulation or 
equivalent test methods approved by the Administrator under Secs. 260.20 
and 260.21.
    (4) It is an oxidizer as defined in 49 CFR 173.151.
    (b) A solid waste that exhibits the characteristic of ignitability
