Accelerated laboratory weathering tests reliably predict field performance of exterior wood coatings.

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

In plain terms

38 studies are indexed, but only 2 have 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.

Supports

Correlation between natural and accelerated weathering of coated wood

2014 · Grade D · Not peer-reviewed

Both accelerated methods reproduced outdoor color and water-repellency trends for tested exterior wood coatings.

Contradicts

Critical view on the possibility of color changes prediction in the surfaces of painted wood exposed outdoors using accelerated weathering in Xenotest

Journal of Coatings Technology and Research · 2018 · Grade D · Not peer-reviewed

The title critically questions predicting outdoor painted-wood color changes using accelerated Xenotest weathering.

Why they differ

Comparable in age, venue and grade — the disagreement is substantive and unresolved.

Effects of UV radiation on natural and synthetic materials.

Andrady AL, Heikkilä AM, Pandey KK et al. · 2023 · doi:10.1007/s43630-023-00377-6

The abstract describes UV degradation of materials but does not compare accelerated tests with field coating performance.

Peer-reviewed

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.
