Description
TR9 is a specialist fire engineering tool used to extend the results of a fire resistance test on a light timber‑framed wall or floor/ceiling system.
When a prototype wall or floor system has passed a fire resistance test, TR9 allows designers to extrapolate those results to similar systems with:
- Greater wall heights
- Longer floor spans
- Different loadings.
This makes it possible to design timber‑framed walls and floor/ceiling systems for fire resistance without repeating full‑scale fire testing, provided the new design stays within defined limits.
