for solids and liquids, if the test is performed with the solid or liquid to be carried or with another

substance having essentially the same physical characteristics:

for liquids in single packagings and for inner packagings of combination packagings, if the test is performed with water:

note: the term water includes water/antifreeze solutions with a minimum specific gravity of 0.95 for testing at - 18 °c.

(a) where the substances to be carried have a relative density not exceeding 1.2:

(b) where the substances to be carried have a relative density exceeding 1.2, the drop height shall be calculated on the basis of the relative density (d) of the substance to be carried, rounded up to the first decimal, as follows:

(c) for light-gauge metal packagings, marked with symbol "rid/adr" according to 6.1.3.1(a) (ii) intended for the carriage of substances having a viscosity at 23 °c greater than 200 mm2/s (corresponding to a flow time of 30 seconds with an iso flow cup having a jet orifice of 6 mm diameter in accordance with iso standard 2431:1993)

(i) if the relative density does not exceed 1.2:

(ii) where the substances to be carried have a relative density (d) exceeding 1.2 the drop height shall be calculated on the basis of the relative density (d) of the substance to be carried, rounded up to the first decimal place, as follows:
