This European Standard specifies requirements for fire resisting data cabinets. Two methods of test are specified to determine the ability of fire resisting data cabinets to protect temperature and humidity sensitive contents from the effects of fire: a fire endurance test and a fire shock and impact test. Two levels of fire severity are specified based upon time of fire exposure; three levels of protection performance are specified using the maximum temperature increases and humidity values permitted within the storage space of the data cabinet. Requirements are also specified for test specimens, documentation to accompany the test specimens, correlation of the test specimens with the documentation, preparation for testing and test procedures. A scheme to classify the fire resisting data cabinets from the test results is given.
