T = 154t0,25 + 20 for t > 21
T = 345 log10
(8(t-20) + 1) + 20 where t is the time from start of test, in minutes (min); T is the mean furnace temperature in degrees Celsius (°C). Further details relating to the practical application of this curve, and other test parameters e.g. tolerances, shall be as given in EN 1363-2. 4.4 Constant temperature attack In addition to the heating regimes given above, the evaluation of smoke barriers and smoke and heat exhaust ventilators is made using a notional constant temperature attack. The specified temperature and the rate at which the temperature is reached, is specified in the relevant test method. 4.5 Specific thermal actions 4.5.1 Smoke control ducts Multi-compartment ducts – standard temperature/time curve. Single compartment ducts – a constant temperature of either 300 °C or 600 °C, following the standard temperature/time curve up to the specified constant temperature. NOTE prEN 1366-9 does not include a test for assessing integrity at 300 °C. 4.5.2 Smoke control dampers Multi-compartment dampers – standard temperature/time curve. Single compartment dampers – a constant temperature of either 300 °C or 600 °C, following the standard temperature/time curve up to the specified constant temperature. NOTE prEN 1366-10 does not include a test for assessing integrity at 300 °C. 4.5.3 Smoke barriers A constant temperature of 600 °C, following the standard temperature/time curve up to the specified constant temperature.

°C, increasing the furnace temperature following a gradient as specified in EN 12101-2. NOTE
°C is an open class for special applications. 5 Resistance to fire performance characteristics 5.1 General The essential requirement ‘safety in case of fire’ of the Construction Products Directive requires the products covered in this standard to be assessed against specified characteristics. These include integrity, insulation, stability, smoke leakage and reliability. This clause provides the necessary details of each of the above characteristics. Where a characteristic may have more than one different definition or type of performance, later clauses identify which specific definition applies to which products. 5.2 Performance characteristics 5.2.1 E – Integrity Integrity E is the ability of a component of a smoke control system to prevent the transmission of fire as a result of the passage of significant quantities of flames or hot gases from the fire to the unexposed side, thereby causing ignition either of the non-fire exposed surface or of any material adjacent to that surface. The assessment of integrity is made on the basis of one or more of the following aspects simultaneously:  cracks or openings in excess of given dimensions;  ignition of a cotton pad;  sustained flaming on the non-exposed side;
