ISO 6444:2005 (R2020)

ISO 6444:2005 describes the method which is to be used to test the behaviour under humidity variations of door leaves placed in successive uniform climates. ISO 6444:2005 can be applied to all door leaves, (e.g. solid doors, hollow core doors, panelled doors and glazed doors), which are nominally flat and rigid, and which contain hygroscopic materials can might influence their behaviour during this test.
