Sec. 261.22  Characteristic of corrosivity.

    (a) A solid waste exhibits the characteristic of corrosivity if a 
representative sample of the waste has either of the following 
properties:
    (1) It is aqueous and has a pH less than or equal to 2 or greater 
than or equal to 12.5, as determined by a pH meter using Method 9040 in 
``Test Methods for Evaluating Solid Waste, Physical/Chemical Methods,'' 
EPA Publication SW-846, as incorporated by reference in Sec. 260.11 of 
this chapter.
    (2) It is a liquid and corrodes steel (SAE 1020) at a rate greater 
than 6.35 mm (0.250 inch) per year at a test temperature of 55 [deg]C 
(130 [deg]F) as determined by the test method specified in NACE 
(National Association of Corrosion Engineers) Standard TM-01-69 as 
standardized in ``Test Methods for Evaluating Solid Waste, Physical/
Chemical Methods,'' EPA Publication SW-846, as incorporated by reference 
in Sec. 260.11 of this chapter.
