Frequently Asked Questions:-

What is BS 476?

The British Standard 476 fire tests for these level of fire resistance elements of structure/materials and grades The tests that dictate the to the Solid Surface industry are the BS476 part 6, appropriate relevant and BS476 part 7.

What is the difference Class A and Class C fire between ratings?

A combustible flame spread Class A, Class B, or Class C based on a material rated as its material will be rated as performance in this test. Class results of results in a A would have a lower, and therefore a better performance rating, than a Class C material. The numeric rating the flame spread test
