This standard specifies a test method that simulates a fire that under well ventilated conditions starts in a corner of a small room with a single open doorway.
It is intended to evaluate the contribution to fire growth provided by a surface product using a specified ignition source.
The test method is suitable for products that for some reason cannot be tested in a small laboratory scale, for example thermoplastic materials, the effect of an insulating substrate, joints, surfaces with great irregularity. Fire testing of insulated building panels is carried out in accordance with the requirements in CAN/ULC-S138, Standard Method of Test for Fire Growth of Insulated Building Panels in a Full-Scale Room Configuration.
The test method is not intended to evaluate the fire resistance of a product.
This test provides data for the early stages of a fire from ignition up to flashover.
