New fire-performance evidence has been added to the GRP Express Assurance Centre. The update makes the test method, product construction and limits of applicability clearer for buyers and designers.
At a glance
- Fire evidence applies to the tested product and configuration.
- Different test standards measure different behaviours.
- A classification is not a complete project fire strategy.
- Confirm resin, thickness, surface and orientation against the report.
What is now visible
The assurance route identifies the report, test method, product reference and controlled revision. This helps users distinguish evidence from general fire-retardant marketing language.
Where a report does not apply to the supplied construction, it should not be used to justify selection.
How to interpret evidence
Flame spread, smoke, heat release, fire resistance and reaction-to-fire classifications are not interchangeable.
Project specifications should state the required method and classification rather than asking only for a fire-rated product.
Product and application
Resin formulation, thickness, surface, mounting, supports and orientation can affect results. Confirm the intended product falls within the evidence scope.
Penetrations, fixings and adjacent materials remain part of the complete fire design.
Approval route
The responsible fire and design teams should assess suitability for the building or infrastructure context.
Retain the report revision and supplied product identity in the project record.
Update checklist
| Check | Why it matters | Action |
|---|---|---|
| Method | Matches project requirement | Read report scope |
| Product | Same resin and construction | Match schedule |
| Result | Correct classification | Record value |
| Application | Mounting and end use | Fire review |
| Supply | Traceable to evidence | Retain documents |

Questions about this update
Does fire-retardant mean non-combustible?
No. Use the precise test result and classification.
Can ASTM and EN results be compared directly?
Not without understanding the different test methods and scopes.
Does the report approve an installation?
No. It supports the project fire assessment.
