E – INTEGRITY
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.
- no flames
- no smoke
- high temperature
EW – INTEGRITY AND RADIATION REDUCTION
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 significant thermal radiation or through an element, or from its non-heated surface to adjacent materials.
- no flames
- no smoke
- lower thermal radiation
EI – INTEGRITY AND 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.
- no flames
- no smoke
- high-temperature insulation
