Liquid

A substance which at 50 °C has a vapour pressure of not more than 300 kPa (3 bar), which is not completely gaseous at 20 °C and 101.3 kPa, and which (a) has a melting point or initial melting point of 20 °C or less at a pressure of 101.3 kPa, or (b) is liquid according to the ASTM D 4359-90 test method or (c) is not pasty according to the criteria applicable to the test for determining fluidity (penetrometer test) described in 2.3.4. NOTE: "Carriage in the liquid state", for the purpose of tank requirements, means: – Carriage of liquids according to the above definition, or – Solids handed over for carriage in the molten state.
