It should also meet the requirements for additional fire resistance.||Thirty times the coating had no blistering, obvious deterioration and softening. Meet additional fire resistance requirements.||qualified|
|11||Fire resistance||When the coating thickness is not more than (5.0±0.5) mm, the fire resistance limit should not be less than 1.0h.
Fire resistance limit judgment:
Loss of carrying capacity -
The maximum deflection of the coated steel beam is L0/20 (L0 is the span of the steel beam in mm).
|The actual coating thickness was 4.5 mm and the fire resistance test was carried out for 150 min.
Fire resistance is equal to 2.5h.
