Siderise are strong advocates of large-scale system testing and have participated in a significant number of such tests (including BS 8414, NFPA 285). This has provided considerable data which is invaluable in determining the performance of our cavity barriers.

What are National Classes (BS) and European Classes (EN) for reaction to fire and fire resistance?

Reaction to fire

National Class: Historically products were tested to BS 476-6 and 7 and then classified as Class 0, Class 1 etc. dependant on their performance.

Reaction to fire national classes have now been removed from Approved Document B for England & Wales (2019 edition).

European Class: Products should now be classified to European Class A1, A2 etc. under EN 13501-1.

Resistance to fire

National Class: BS 476-20 is a furnace test to prove fire resistance performance in terms of integrity (E) and insulation (I) in minutes.

For example, a product may achieve 120 minutes integrity and 90 minutes insulation.

European Class: Products should be tested to the relevant EN standard such as EN 1364-4 or EN 1366-4. The fire resistance in terms of integrity and insulation is then classified to EN 13501-2.

For example, a product may achieve 120 minutes integrity (E 120) and 90 minutes insulation (I 90), this would receive a classification of EI 90.

Approved Document B for England & Wales (2019 edition) now lists classification to EN 13501-2 as the primary route to compliance. BS 476-20 is listed as an alternate route to compliance.
