Symbols in the classification of fire resistance of a construction

bir konstrueksiyonun yangn direncinin snflandrlmasnda kullanlan simgeler v2

E - ıntegrity

  • no flames
  • no smoke
  • high temperature

Integrity (E) is the ability of a component or construction to maintain the integrity of the element on one side only, without spreading the fire to a non-heated side as a result of penetration of flames or hot gases.

EW - integrity and radiation reduction

  • no flames
  • no smoke
  • lower thermal radiation

Reduction of radiation (W) is the ability of a component or construction to maintain the integrity of the element on one side only, to reduce the likelihood of fire spreading that may result from signi cant thermal radiation or through an element, or from its non-heated surface to adjacent materials.

EI - integrity and insulation

  • no flames
  • no smoke
  • high temperature insulation

Insulation (I) is the ability of a component or construction to maintain the integrity of the element on one side only, without spreading the fire as a result of a significant heat flow from a heated side to a non-heated side. During the fire, the construction on the non-heated side reaches a temperature of not more than +140°C up to +180°C.
