Test methods for external fire exposure to roofs algolia-search-ignore

Test methods for external fire exposure to roofs algolia-search-ignore1 Scope This Technical Specification specifies four methods for determining the performance of roofs to external fire exposure. The four methods assess the performance of roofs under the following conditions: test 1 with burning brands; test 2 with burning brands and wind; test 3 with burning brands, wind and supplementary radiant heat; test 4 with two stages incorporating burning brands, wind and supplementary radiant heat. The tests assess the fire
