To what temperature are fire safes, filing cabinets, and media or data cabinet tested?
Fire Endurance Test: Contents, which may consist of paper, computer media, or both, are distributed loosely throughout the fire resistant product to be tested. For products testing to meet the Class 350 or 125 requirements, the product is first conditioned for at least twelve hours prior to the test. This conditioning insures that the temperature of the interior at the start of the test will be between 65° and 75° and the relative humidity will be below 65%. This is considered to be equivalent to the normal room conditions where the documents will be stored. Depending upon the classification time being tested, the furnace heat rises at a carefully monitored rate until the specified temperature is reached. Great care is taken to make sure the furnace heat is distributed evenly over the exposed surfaces of the products.
