The effectiveness of the United Nations' leakproofness tests

The regulations for the packaging of dangerous goods, which are applicable world-wide for the various modes of transport, include performance tests. It is impossible to conduct laboratory tests for every environmental condition, but the tests can produce a conservative estimate of the situation during transport. This paper analyses the so-called leakproofness test as one of the design-type tests for packagings covered by the United Nations' (UN) recommendations for dangerous goods.
