Water-cooled heat radiation flux sensor The results can be traced back to the US NIST.
Electrical control cabinet Sample holder Perpendicular to the radiant panel, and the standard scale mark above, the critical heat radiant flux can be calculated according to the flame propagation distance.


Frequently Asked Questions:-

What is BS 476?

BS 476 refers to the British standard. This test standard is split into for fire tests on structures two parts: Part 6 and Part 7. Part 7 specifies the test building spread of flame along materials and method for measuring the lateral the surface of a test specimen.

What is fire propagation index?

a fire propagation made by an essentially flat material index, measure of the contribution to the growth that provides a, composite or assembly. It is primarily comparative the performance of fire intended for the assessment of internal wall and ceiling linings.

What is the difference between Class 1 and Class 0 fire rating?

Class 1 – Protects the spread of flames Class 0 – Protect your surface from surface from the spread of flames AND limits the from the surface amount of heat released during a fire.
