適用范圍：This part of this European Standard 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 andhumidity sensitive contents from the effects of fire: a fire endurance test and a fire shock and impact test. Twolevels of fire severity (S 60 and S 120) based upon time of fire exposure; and three protection classes (P, D andDIS) are specified using the maximum temperature increases and humidity values permitted within the storagespace 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, correlationof 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 (seeTable 1).Cabinets having the same design, protection and construction features (type and thickness of construction andprotective materials, rebate geometry, locking, etc.) will only give the same fire protection classification as that of atest specimen if they are of similar internal dimensions. The maximum difference in internal dimensions (height,width and depth of the storage space, measured from wall to wall) to which the test classification could apply is +15 %. Cabinets having internal dimensions which differ by more than this amount from that of the tested specimenshould be submitted to an extra test.The wall, ceiling and door thicknesses should not be below the specified minimum limit of the type-tested thicknessby more than 3 %.Diskette inserts should only be installed in data cabinets having the same design as the series of protection class S60 P and S 120 P, respectively, in which the insert has been tested in accordance with 5.1.2. Where several insertsare installed, they should be 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 should not exceed 50 % of the total internal volume or 50 % ofthe internal height, respectively, of the data cabinets into which they are installed. The dimensions of the insert canbe adapted by increasing the width and depth to the corresponding dimensions of the data cabinets. A reduction ofthese 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 decidingthe permitted diskette insert installations. For a permitted installation, the temperature increase of the intended datacabinet (?Ta K) should not exceed the temperature increase of the tested data cabinet (?Tb K) in which thediskette insert has been type-tested by more than the difference between the maximum value for the diskette insert(?Ti K) and the maximum admissible temperature increase (30 K), i.e: ?Ta - ?Tb ≤ 30 K - ?Ti (See example inAnnex B).A description of the installation of the diskette inserts should be given in the technical documentation of themanufacturer.
