Fire penetration seals, bs 476:1987 part 20 are systems or materials used to prevent the spread of fire through penetrations in fire-resistant barriers, such as walls, floors, and ceilings. They are designed to maintain the integrity of the barrier by sealing any openings created by pipes, ducts, cables, or other services passing through it. These seals must be able to withstand the heat of a fire and prevent flames, smoke, and hot gases from passing through the penetration and compromising the fire-resistance of the building. The British Standard 476:1987 Part 20 outlines the testing procedures and performance criteria for fire penetration seals.
