Reply #180: The use of the envelope curve is indeed conservative. [View All]

[Carefulplease]

I have no idea how you interpret those statement that you emphasized such that the data ought to be disqualified. I reported factual data you challenged me to find.

The temperatures recorded in different locations vary. I did not mention the envelope curve from the NFST fire test database. Why should I have? I reported on the raw data provided in this paper. The envelope curve is conservative (it expresses a lower bound) because it only displays the maximum temperature reached at any time from *just* three locations in the compartment. If the spatial peak in temperature happens to be located anywhere else than at those precise locations then the actual highest temperature at that time would be higher. In other words, including the data from more locations in the composite graph would have bumped up the envelope curve for some time intervals. Why is that significant? Do you fear that I might have underestimated the average temperature in this test fire?

The fact remains that temperature above 1200C were reached within 40 minutes during the second test that included a more realistic ventilation area. You did not comment on that one either.
