Except as provided for in 22.214.171.124.5.2, 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, sub- section 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 126.96.36.199.5.1,
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 188.8.131.52, 184.108.40.206 and 220.127.116.11 to 18.104.22.168.
If substances of Class 3, as a result of admixtures, come into categories of hazard 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 danger.
NOTE: For the classification of solutions and mixtures (such as preparations and wastes) see also 2.1.3.
On the basis of the test procedures in accordance with 22.214.171.124 and 2.3.4, and the criteria set out in 126.96.36.199.1, 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 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 188.8.131.52.
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.
Radioactive material means any material containing radionuclides where both the activity concentration and the total activity in the consignment exceed the values specified in 184.108.40.206.2.1 to 220.127.116.11.2.6.
Contamination means the presence of a radioactive substance on a surface in quantities in excess of 0.4 Bq/cm2for beta and gamma emitters and low toxicity alpha emitters, or 0.04 Bq/cm2for all other alpha emitters.Non-fixed contamination means contamination that can be removed from a surface during routine conditions of carriage.Fixed contamination means contamination other than non-fixed contamination.
A1 and A2
A1 means the activity value of special form radioactive material which is listed in the Table in 18.104.22.168.2.1 or derived in 22.214.171.124.2.2 and is used to determine the activity limits for the requirements of ADR.
A2 means the activity value of radioactive material, other than special form radioactive material, which is listed in the Table in 126.96.36.199.2.1 or derived in 188.8.131.52.2.2 and is used to determine the activity limits for the requirements of ADR.
Fissile nuclidesmeans uranium-233, uranium-235, plutonium-239 and plutonium-241. Fissile materialmeans a material containing any of the fissile nuclides. Excluded from the definition of fissile material are the following:
(a)Natural uranium or depleted uranium which is unirradiated;
(b)Natural uranium or depleted uranium which has been irradiated in thermal reactors only;
(c)Material with fissile nuclides less than a total of0.25g;
(d)Any combination of (a), (b) and/or (c).
These exclusions are only valid if there is no other material with fissile nuclides in the package or in the consignment if shipped unpackaged.
Low dispersible radioactive materialmeans either a solid radioactive material or a solid radioactive material in a sealed capsule, that has limited dispersibility and is not in powder form.
Low specific activity (LSA) materialmeans radioactive material which by its nature has a limited specific activity, or radioactive material for which limits of estimated average specific activity apply. External shielding materials surrounding the LSA material shall not be considered in determining the estimated average specific activity.
Low toxicity alpha emittersare: natural uranium; depleted uranium; natural thorium; uranium-235 or uranium-238; thorium-232; thorium-228 and thorium-230 when contained in ores or physical andchemical concentrates; or alpha emitters with a half-life of less than 10 days.
Special form radioactive materialmeans either:
(a)An indispersible solid radioactive material; or
(b)A sealed capsule containing radioactive material.
Specific activity of a radionuclidemeans the activity per unit mass of that nuclide. The specific activity of a material shall mean the activity per unit mass of the material in which the radionuclides are essentially uniformly distributed.
Surface contaminated object (SCO) means a solid object which is not itself radioactive but which has radioactive material distributed on its surface.Unirradiated thoriummeans thorium containing not more than 10-7g of uranium-233 per gram of thorium-232.
Unirradiated uraniummeans uraniumcontaining not more than 2 ×103Bq of plutonium per gram of uranium-235, not more than 9×106Bq of fission products per gram of uranium-235 and not more than 5 ×10-3g of uranium-236 per gram of uranium-235.
Uranium - natural, depleted, enrichedmeansthe following:
Natural uraniummeans uranium (which may be chemically separated) containing the naturally occurring distribution of uranium isotopes (approximately 99.28% uranium-238, and 0.72% uranium-235 by mass).
Depleted uraniummeans uranium containing a lesser mass percentage of uranium-235 than in natural uranium.
Enriched uraniummeans uranium containing a greater mass percentage of uranium-235than0.72%.
In all cases, a very small mass percentage of uranium-234 is present.
