Based on Hamins and McGrattan (2007), pp. 5-1–5-2.<br /> <br /> Original illustration for [[Uncertainty analysis]], level 4 Expert.<br /> <br /> * Source basis: Hamins and McGrattan (2007), p. 5-1 (HRR uncertainty 15 % to 25 %, MQH correlation) and p. 5-2 (two-thirds rule; layer height 1 % to 2 %)<br /> * Alt text: Chart: temperature uncertainty rises at two-thirds of the heat release rate uncertainty, while layer height uncertainty stays near 1 to 2 %.<br /> <br /> == Licensing ==<br /> New drawing by Fire Safety Academy. © Fire Safety Academy.</div>
