The Model Regulations cover the classification of dangerous goods and their listing, the use, construction, testing and approval of packagings and portable tanks, and the consignment procedures (marking, labelling, placarding and documentation). They aim at ensuring a high level of safety by preventing accidents to persons and property and damage to the environment during transport and, providing at the same time, a uniform regulatory framework which can be applied worldwide for national or international transport by any mode. This revised edition contains new and revised provisions concerning, inter alia: classification of solid oxidizing substances; transport of adsorbed gases; lithium batteries (including damaged or defective lithium batteries, lithium batteries for disposal or recycling); asymmetric capacitors; discarded packagings; ammonium nitrate and radioactive material; testing of gas cartridges and fuel cell cartridges; marking of bundles of cylinders; and the applicability of ISO standards to the manufacture of new pressure receptacles or service equipment.
