The fire resistance classification is related to the
complete glazed assembly.
Classes are expressed by the letter(s) representing
the considered functional requirement(s),
followed by the performance time in minutes.
Example: E130 = 30 minutes fire resistance plus
30 minutes insulation. |

gases and smoke. |
"The ability of the element of construction with
a separating function to withstand fire
exposure on one side only, without the
transmission of fire to the non-fire side as a
result of the passage of significant quantities of
flames or hot gases from the fire to the non-fire
side, thereby causing ignition of the non-fire
exposed surface or any materials adjacent to
that surface."

"The ability of the element of construction with
a separating function to withstand fire
exposure from one side only for a period of
time, while the measured radiated heat in font
of the glazing is below a specified level.” –

"The ability of the element of construction with
a separating function to withstand fire
exposure on one side only, without the
transmission of fire exposure on one side only,
without the transmission of fire to the non-fire
side as a result of significant conduction of
heat from the fire side to the non-fire side,
thereby causing ignition of the non-fire
exposed surface or any material in contact
with that surface and the ability to provide a
barrier to heat sufficient to protect people near
the element of construction for the relevant
classification period.” –
