Charring rates of cross-laminated timber under standard fire exposure are predictable within the Eurocode 5 design assumptions.

Under review — the register is reading the literature and will publish a conclusion once directional evidence has been indexed.

In plain terms

36 studies are indexed, but only 1 has been classified for or against — too few to state a consensus, so no share is calculated yet.

This sentence is generated from the same numbers shown below — consensus share, confidence band and the number of indexed studies. Open any section to see exactly how it was reached.

Where the literature disagreesNo direct contradictions in the indexed pool

No direct contradictions in the indexed pool. That is not the same as agreement — it can also mean too few directional studies have been published to disagree yet.

Delamination and char fall-off in fire exposed cross-laminated timber loaded in shear

Antonela Čolic, Felix Wiesner, Luke Bisby et al. · 2021 · Proceedings of the 12th Asia-Oceania Symposium on Fire Science and Technology (AOSFST 2021) · doi:10.14264/a067f63

The title identifies delamination and char fall-off but gives no comparison between measured charring and Eurocode 5 assumptions.

Roy Crielaard, Jan-Willem van de Kuilen, Karel Terwel et al. · 2019 · Fire Safety Journal · doi:10.1016/j.firesaf.2019.01.008

The title concerns CLT self-extinguishment and provides no finding about Eurocode 5 charring-rate assumptions.

Fire Safety of Mass timber Buildings with CLT in USA

David Barber · 2018 · Wood and Fiber Science · doi:10.22382/wfs-2018-042

Paulo B. Cachim, Jean-Marc Franssen · 2009 · Fire Technology · doi:10.1007/s10694-009-0092-x

Stance classification is automated and reviewed against each record's own abstract; it is a reading of the literature, not a measurement. The Evidence Score is a rule-based function of indexed metadata under method WI-EV v1.0.0 and does not constitute proof of the statement.
