Due to the historical absence of dedicatednBritish Standard fire tests for fire-stopping, ‘ad hoc’ or ‘indicative tests’nhave often been used to demonstrate the fire performance of fire-stoppingnproducts and systems. These are subject to widely varying interpretations andnthis can inevitably lead to confusion for the specifier, specialist firenprotection contractor, building control personnel and other end users. It maynalso lead to fire-stopping installations that are unable to provide thenrequired standard of protection.
Some less than scrupulous manufacturersnhave also used the confusion over ad-hoc and indicative tests to place productsnon the market that have not been adequately tested and, if were so tested,nwould probably not achieve the required performance if tested to EN1366-3
Because of the uncertainty over ad-hoc and indicativenfire testing following the principles of British standard fire resistancentests, using the BS476 series, Pyroplex have taken the more onerous root innterms of testing our products to a more robust method of testing and includingnCE Marking, by adopting to the European Technical Assessment.
