INSAT standards organization has published a draft standard pr INSTA 900-3 : 2013(E) - (Residential sprinkler systems — Part 3: Watermist systems equivalent to residential sprinklers). This standard continues the work of the Nordic group to produce a series of standards for Residential Sprinkler System and part three coves the test methods for alternative water base fire fighting systems as required in INSTA 900-1 and 2.
The INSTA 900-3 standard allows equivalency to be established using any of three different fire test protocols: UL 1626, FM 2030 or DD 8458. We are informed that it will not be long before DD 8458 to be converted into a full British Standard.
