Direct answer
B1 describes the assessed burning behavior of the tested product under the applicable GB methods. It does not replace the fire design, assembly assessment or approval required by another country or municipality.

What buyers should verify
Fire performance is evaluated for the tested product and conditions. The complete building result also depends on panel joints, supporting structure, penetrations, flashings, interior finishes and the intended occupancy.
Overseas buyers should provide the project location and approval requirements so the available report can be reviewed against local regulations before the order is finalized.
