GB 16810-1997 specifies the test method for fire resistance performance of safes. Linear dispersion heating of safes in a simulated fire environment according to specific temperature rise. The fire resistance performance is judged by monitoring the temperature change in the cabinet, observing the deformation of the cabinet, the sealing situation and the difficulty of opening the cabinet door. The standard specifies the test equipment, heating procedure, temperature Measuring location and accuracy requirements provide a scientific basis for uniformly evaluating the fire resistance performance of safes to ensure that they can effectively protect the internal items in the fire. Provide mass control criteria for the production and application of safes.
