Liquid
Liquid means a material, other than an elevated temperature material, with a melting point or initial melting point of 20 C (68 F) or lower at a standard pressure of 101.3 kPa (14.7 psia). A viscous material for which a specific melting point cannot be determined must be subjected to the procedures specified in ASTM D 4359 (IBR, see 171.7) or to the test for determining fluidity (penetrometer test) prescribed in section 2.3.4 of Annex A of the European Agreement Concerning the International Carriage of Dangerous Goods by Road (ADR) (IBR, see 171.7).
