Packaging must be subjected to performance tests designed to ensure that the packages tested will not lose any of their contents under normal transport conditions. The severity of the tests on the packaging is dependent on the degree of danger of the intended contents as expressed by their packing group. These packages will bear UN markings (see para 8.7 below)
8.6.3.2. Limited Quantity Packaging (DGR 2.7, 5.0.3, 7.1.5.3)
Limited Quantity Packaging provisions recognize that may dangerous goods in small quantities present a reduced hazard, and can be safely transported in good quality Packaging. These Limited Quantity packaging must be made to the same construction requirements as the UN specification packaging, but instead of the UN testing they must be capable of withstanding a 1.2 meter (4 ft) drop test and a 24 hour stacking test as described in DGR 6.7. Such Packaging must be marked with the Limited Quantities mark to indicate that they meet these requirements. ‘’Y’’ Packing Instructions are used for dangerous goods that are permitted in Limited Quantities.
Note
Limited Quantity Packaging does not require UN specification markings.
