Summary

Upper layer temperature from the MQH correlation for the example room, 60 s after ignition and after the lining has heated through. Based on Walton and Thomas (2002), pp. 3-176–3-177.

Original illustration for MQH correlation, level 4 Expert.

Source basis: Walton and Thomas (2002), p. 3-176 (Equation 11, limit of about 600 °C) and p. 3-177 (example room and hk values); Iqbal and Salley (2004), pp. 13-3–13-4 (500 °C flashover criterion)
Alt text: Line chart: upper layer temperature rises with heat release rate, faster for warm walls after 10 minutes than after 60 seconds.
