The average service life of high-quality fireproof safe is twenty five (25) years that is longer than the service life of conventional office equipment. Just how long fireproof safe will serve depends not only on the manufacturer, the use of and compliance with safety holder, but also on the level of caution at its exploitation.
What is a fireproof safe? Its main and perhaps basic purpose is to ensure the necessary protection of the property, which is stored in it from the fire. Such a fireproof safe, as well as other refractory structures and products are subject to special specific tests as a result of that it either receives or does not receive the relevant quality document.
Abbreviation: The values of 30, 60 or 120, and the letters “MDS” or “P”. These symbols and figures to explain the period of time (in minutes): magnetic data security (abbreviation “DS”); security, safety and preservation of paper (abbreviation “P”). Paper (not according to its class or density) will begin to turn yellow and burn at a temperature above 173 * C (no humidity effect), and the magnetic media (tapes, DVD / CD etc.) will come in unsuitability temperature is raised to 60 * C and a moisture content greater than 80%.
What is the dissimilarity between fireproof safes and fire-resistant cabinets? The answer is that the fire-resistant cabinets do not save from a fire or blaze its contents. After this safe being on fire, even for a very short time, there would be only ashes inside. Fireproof safes will burn the outside, but will protect its internal contents. It may burn out itself, but it will keep papers, documents or other content. Matched fire class of products will affect the length of his counter to the fire.
How do the fire trials run? During this operation, the product is kept in an oven at a temperature of 1000 C, until the moment when t in the middle of the construction reaches the self-ignition temperature: for magnetic storage, DVD / CD – 55 C and at a relative humidity above 80%; for the paper it is equal to 170 C. After passing the tests close to the actual fire conditions, products are issued by the relevant quality certificates: A2P and VDMA (France and Germany, respectively). Test simulates the difficult circumstances of the highest fires group:
– the temperature is increasing rapidly;
– the dynamic overloads are created, close to the overload at the destruction of the building or ceilings collapses;
– thermal attack of powerful water jet is run;
At the end of the tests, the experts assess the results of testing, and then those products receive or not certificates of quality and conformity to classes.
