Viscous liquids

Except as provided for in, viscous liquids which:
- have a flash-point of 23 °C or above and less than or equal to 60 °C;
- are not toxic, corrosive or environmentally hazardous;
- contain not more than 20% nitrocellulose provided the nitrocellulose contains not more
than 12.6% nitrogen by dry mass; and
- are packed in receptacles of not more than 450 litre capacity;
are not subject to ADR, if:
(a) in the solvent separation test (see Manual of Tests and Criteria, Part III, sub-section 32.5.1),
the height of the separated layer of solvent is less than 3% of the total height; and
(b) the flowtime in the viscosity test (see Manual of Tests and Criteria, Part III, subsection
32.4.3), with a jet diameter of 6 mm is equal to or greater than:
(i) 60 seconds; or
(ii) 40 seconds if the viscous liquid contains not more than 60% of Class 3 substances.

Viscous liquids which are also environmentally hazardous, but meet all other criteria in,
are not subject to any other provisions of ADR when they are carried in single or combination
packagings containing a net quantity per single or inner packaging of 5 litres or less, provided the
packagings meet the general provisions of, and to

If substances of Class 3, as a result of admixtures, come into categories of risk different from those to
which the substances mentioned by name in Table A of Chapter 3.2 belong, these mixtures or
solutions shall be assigned to the entries to which they belong on the basis of their actual degree of
NOTE: For the classification of solutions and mixtures (such as preparations and wastes) see also

On the basis of the test procedures in accordance with and 2.3.4, and the criteria set out in, it may also be determined whether the nature of a solution or a mixture mentioned by name
or containing a substance mentioned by name is such that the solution or mixture is not subject to the
provisions for this Class (see also 2.1.3).

Substances not accepted for carriage

Substances of Class 3 which are liable to form peroxides easily (as happens with ethers or with certain
heterocyclic oxygenated substances) shall not be accepted for carriage if their peroxide content,
calculated as hydrogen peroxide (H2O2), exceeds 0.3%. The peroxide content shall be determined as
indicated in

Chemically unstable substances of Class 3 shall not be accepted for carriage unless the necessary
precautions have been taken to prevent the possibility of a dangerous decomposition or
polymerization under normal conditions of carriage. For the precautions necessary to prevent
polymerization, see special provision 386 of Chapter 3.3. To this end particular care shall be taken to
ensure that receptacles and tanks do not contain any substances liable to promote these reactions.

Liquid desensitized explosives other than those listed in Table A of Chapter 3.2 shall not be accepted
for carriage as substances of Class 3.
