    Abstract - (Show below) - (Hide below)

    Specifies a method of test and criteria for vertical and horizontal ducts under standardized fire conditions. The general purpose is to measure the ability to resist the spread of fire from one fire compartment to another without the aid of fire dampers. Is applicable to vertical and horizontal ducts with or without branches, taking into account joints, air supply and exhaust openings and suspension devices etc.
