note 1: examples to explain the use of the table
classification of a single substance
description of the substance to be classified:
an amine not mentioned by name meeting the criteria for class 3, packing group ii as well as those for class 8, packing group i.
procedure:
the intersection of line 3 ii with column 8 i gives 8 i.
this amine has therefore to be classified in class 8 under:
un no. 2734 amines liquid, corrosive, flammable, n.o.s. or un no. 2734 polyamines, liquid, corrosive, flammable, n.o.s.
packing group i
classification of a mixture
description of the mixture to be classified:
mixture consisting of a flammable liquid classified in class 3, packing group iii, a toxic substance in class 6.1, packing group ii and a corrosive substance in class 8, packing group i.
procedure:
the intersection of line 3 iii with column 6.1 ii gives 6.1 ii. the intersection of line 6.1 ii with column 8 i gives 8 i liq.
this mixture not further defined has therefore to be classified in class 8 under: un no. 2922 corrosive liquid, toxic, n.o.s. packing group i.
note 2: examples for the classification of mixtures and solutions under a class and a packing group:
a phenol solution of class 6.1, (ii), in benzene of class 3, (ii) is to be classified in class 3, (ii); this solution is to be classified under un no. 1992 flammable liquid, toxic, n.o.s., class 3, (ii), by virtue of the toxicity of the phenol.
a solid mixture of sodium arsenate of class 6.1, (ii) and sodium hydroxide of class 8, (ii) is to be classified under un no. 3290 toxic solid, corrosive, inorganic, n.o.s., in class 6.1 (ii).
a solution of crude or refined naphthalene of class 4.1, (iii) in petrol of class 3, (ii), is to be classified under un no. 3295 hydrocarbons, liquid, n.o.s. in class 3, (ii).
a mixture of hydrocarbons of class 3, (iii), and of polychlorinated biphenyls (pcb) of class 9, (ii), is to be classified under un no. 2315 polychlorinated biphenyls liquid or un no. 3432 polychlorinated biphenyls solid in class 9, (ii).
a mixture of propyleneimine of class 3, and polychlorinated biphenyls (pcb) of class 9, (ii), is to be classified under un no. 1921 propyleneimine, inhibited in class 3.
