该测试主要用于防水或提供一定程度“防水性”的包装。试验在准备运输的包装上进行，可能构成试验顺序的一部分。原理:对包装进行调节，然后将其完全浸入水中，取出，排水，并在调节空气中干燥。浸泡时间、排水和干燥时间以及大气条件是预先确定的。

The test is principally intended for packages which are waterproof or which are intended to provide some degree of "waterproofness". The test is performed on the package as prepared for transport and may form part of a test sequence. Principle: Conditioning of the package, followed by complete immersion in water, removal and draining and drying in the conditioning atmosphere. The time of immersion, time of draining and drying and the atmospheric conditions are predetermined.
