Researched were samples with dimensions of 100 × 100 × 20 mm, dried at a temperature of 103 ± 2 °C to water content of 0 wt%. The orientation of samples during the test was horizontal. The initiatory parameters (critical heat flux density and surface temperature in the time of initiation) were set on a conical calorimeter using a testing procedure in accordance with ISO 5660-1:2015. The testing procedure according to the ISO standard was supplemented by a thermocouple of NiCr-Ni type, which measured the surface temperature of the sample during the test. Critical heat flux density was set by using an ignition initiator (critical heat flux for piloted ignition, in accordance with ISO 5660-1:2015) and without an ignition initiator (critical heat flux for autoignition, modified testing procedure). Critical heat flux density was defined from statistical dependence of initiation time exponentiated by -1/2 from the heat flux density. Critical heat flux density for piloted ignition was10.70 kW·m-2 and critical heat flux density for autoignition was 28.90 kW·m-2. The average surface temperature of the sample in the moment of piloted ignition was 335 ± 59 °C, and in the moment of autoignition 533 ± 63 °C.
