FICHET BAUCHE ORDINA 815 & 525 CABINETS
Fire has always been a very serious hazard for a company, and this hazard has greatly increased with the advent of data processing. The data carriers used are in fact more exposed than documents on paper, not only because of their "lower resistance" to heat but also because of the great concentration of data recorded in a very small volume.
Again compared with documents on paper, it should also be pointed out that data carriers are very sensitive to moisture and humidity and additionally can suffer "losses" due to demagnetisation.
The new range of heat-resisting and fireproof cabinets intended for the protection of computer data, which includes the "Ordina" 815 and 525, is the result of Fichet-Bauche's desire to meet the most stringent requirements with regard to fire resistance.
The substantial resources made available to its designers, a comprehensive test programme and extensive industrial facilities using advanced technology have enabled Fichet-Bauche to develop the "Ordina" range.
The Outer Cabinet
This outer cabinet is formed of two sheet steel envelopes, between which our special heat-resisting and fireproof material is poured. This is a cellular, homogeneous and stable aggregate incorporating thermally treated natural minerals and various additives. In a fire, its task is to act as a real chemical barrier, releasing a substantial part of its water of crystallisation in the form of vapour (steam).
An initial barrier to the build-up of the external temperature is thus formed.
The Internal Container
Its design makes use of the latest and most appropriate techniques in the field of insulation and sealing.
Located behind the first "barrier" formed by the outer cabinet, its role is to lower the internal temperature to a level compatible with that which can be tolerated by "sensitive" surfaces (magnetic media).
The Door Leaves
The leaves of the doors are of the "baffle" type and when closed, they interlock in matching recesses in the frame to form a substantial obstacle to the penetration of heat.
These are distributed around the perimeter of the doors of the outer cabinet and effectively complete the thermal insulation of the leaves and "seal" them against flames.
Fire and Drop Tests
C.S.T.B. in FRANCE
The "ORDINA" 815 has successfully completed tests at the Centre Scientifique et Technique du Batiment (Scientific and Technical Building Centre) in Champs-sur-Marne (77).
Fire resistance test (duration: 2 hours)
• Various magnetic media were arranged inside the cabinet, together with measuring instruments.
• The cabinet was placed in the furnace and the burners were lit.
• The temperature inside the furnace rose to 1,029 °C after two hours (in accordance with the international "temperature/ time" curve).
• The heating was completed. The furnace was opened and the cabinet hosed down.
• The cabinet was opened without any difficulty.
Drop test (heating: 1 1/2 hours, drop: 4.50 m, (15 feet), heating: 30 min)
• The cabinet was placed in the furnace and heated for 1 hr 30 min to 986 °C.
• The cabinet was removed from the furnace. lifted to 4.50 m and dropped on to a bed of rubble.
• The cabinet was replaced in the furnace to be reheated for 30 min to 925 °C.
• The cabinet was finally removed from the furnace and hosed down. Once again, it could be opened without difficulty. During the two tests, the various measuring instruments placed inside the cabinet indicated a temperature and relative humidity rate well below the permitted limits.
The recorded magnetic tapes placed in the cabinets for these two tests were recovered intact (see the testimonial below).
B.T.U. in GERMANY (V.D.M.A.)
The "Ordina" 815 unit was successfully tested at the Brunswick Technical University, Germany, by the "Institute for construction materials, permanent building and fire protection". The tests were carried out in accordance with the fire resistance conditions for heat-resisting cabinets and other containers, as set out in V.D.M.A. standard 24991, part 1, June 1979 version. The test consisted of a fire resistance test and a fire and drop test.
Fire Resistance Test
• The cabinet was placed in the furnace. During the period of exposure to the flames (1 hour) the average temperature inside the furnace was maintained in accordance with DIN 4102, part 2, September 1977 version, section 524.
• The burners were stopped. The cabinet remained in the furnace until the interior temperature of the cabinet reached its maximum and began to fall.
• The cabinet was then removed from the furnace and opened.
• The furnace was pre-heated for 30 minutes.
• The cabinet was put quickly into this pre-heated furnace. The temperature was raised to 1,090 °C in 15 minutes and held at that level for a further 15 minutes.
• At the end of this period, the cabinet was withdrawn from the furnace, lifted to 9.15 m (30 feet) and dropped on to rubble.
• The cabinet was then returned to the furnace for a further period of heating. The temperature was raised to 840 °C in 5 minutes and held for 25 minutes.
• The furnace burners were stopped. Depending on the time required in the previous test to reach the maximum temperature, the cabinet was again kept in the furnace during the cooling period.
• The cabinet was removed from the furnace and opened.
The two tests were successful. The "Ordina" 815 was therefore (as all the models of the range) awarded the RG 626/7 label in conformity with class S 60 D.
