90 minutes fire cabinet explosion-proof cabinet is to follow what criteria? EN 14470-1 standard. EN 14470-1 is a safety standard established in Europe in April 2004 for the storage of chemicals. Most of the domestic understanding of FM safety certification, the EN 14470-1 standard to understand very few people, in fact, EN 14470-1 standard is much higher than the FM standard. The EN 14470-1 standard contains three main safety requirements: Reduce the fire caused by chemicals stored in safety cabinets, and improve the protection of these materials in the event of fire. The latter thus thus develop a refractory time (FR, unit: minute) to reduce the discharge of chemical gases into the environment, retaining chemical gas leakage in the cabinet. EN14470-1 contains 4 classes - flame retardant time of 15, 30, 60 and 90 minutes, respectively - to suit the different needs of EU member states. This standard is not entirely acceptable to every Member State, since the new standards do not replace existing national regulations for certain EU Member States dealing with flammable liquids. In the event of a fire, it must be ensured that the chemicals stored in the safety cabinet will not create additional risks in less than 15 minutes to prevent the spread of fire. EN 14470-1 safety cabinets according to their fire resistance can make the following classification: Type 15 - fire resistance of safety cabinets of not less than 15 minutes; Type 30 - fire resistance of safety cabinets of not less than 30 minutes; Type 60 - fire resistance of safety cabinets of not less than 60 minutes; Type 90 - fire resistance of safety cabinets of not less than 90 minutes;
