This document specifies requirements for fire resisting data cabinets and diskette inserts. 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 (S 60 and S 120) based upon time of fire exposure; and three protection classes (P, D and DIS) are specified using the maximum temperature increases and humidity values permitted within the storage space of the data cabinet. Diskette inserts (DI 60 P/DIS and DI 120 P/DIS) are installed in data cabinets of protection class S 60 P or S 120 P, respectively, and subjected to a fire endurance test (see 5.1.2). Requirements are also specified for test specimens, the technical documentation for the test specimen, correlation of the test specimen with the technical documentation, preparation for type testing and test procedures. A scheme to classify the fire resisting data cabinets and diskette inserts from the test results is also given (see Table 1). Diskette inserts are only installed in data cabinets having the same design as the series of protection class S 60 P and S 120 P, respectively, in which the insert has been tested in using methods defined in 5.1.2. Where several inserts are installed, they are built in one beside the other or one above the other from bottom to top, respectively. The volume and total height of the installed inserts do not exceed 50 % of the total internal volume or 50 % of the internal height, respectively, of the data cabinets into which they are installed. The dimensions of the insert can be adapted by increasing the width and depth to the corresponding dimensions of the data cabinets. A reduction of these dimensions as well as a change of the height is only admitted within the specified tolerance. The temperature increases during type-tests on data cabinets and diskette inserts will be considered in deciding the permitted diskette insert installations. For a permitted installation, the temperature increase of the intended data cabinet ( ) does not exceed the temperature increase of the tested data cabinet ( ) in which the diskette insert has been type-tested by more than the difference between the maximum value for the diskette insert ( ) and the maximum admissible temperature increase (30 K), i.e (See example in Annex B). A description of the installation of the diskette inserts can be given in the technical documentation of the manufacturer.
