13、was adopted by CEN on the strength of its acceptance by the following Member countries: Austria, Belgium, France, Germany, Greece, Italy, Netherlands, Norway, Switzerland, United Kingdom. CEN EN*43 85 3404589 0004072 5 1 Object This standard describes the method which is to be used to test the behav
14、iour, under humidity variations, of door leaves placed in successive uniform climates. 2 Field of application This standard can be applied to all doors which are nominally flat and rigid, and which contain a sufficient quantity of hygroscopic materials that might influence their behaviour during thi
15、s test. 3 References EN 24 : 1974 Doors. Measurement of defects of general flatness of door leaves 4 Principle of the fest The test consists of placing the door leaves for a determined duration in successive uniform climates and measuring any changes in general flatness and noting damage which resul

18、 be maintained as close as possible to the nominal values. 5.6 The duration of exposure in each of the two climates shall be 7 days for unfinished doors and 21 days for all other doors. If the test house considers that the test can be stopped at a shorter duration, it shall justify its decision. 6 E
