Guaranteed fire resistance; Class 0
The ‘BS476 Class 0’ fire resistance rating is the most demanding rating on the market today. To achieve class 0 the product must
achieve:
• BS476 part 7, Surface spread of flame, Class 1
• BS476 part 6, Fire propagation, Index I <12 and i1 < 6
This means that the material does not spread flames and limits the amount of heat released from the surface during a fire.
