The standard fire exposure temperature in CAN/ULC-S101, “Standard Method of Fire Endurance Tests of Building Construction and Materials”, is the same as in CAN/ULC-S124, “Standard Method of Test for the Evaluation of Protective Coverings for Foamed Plastic”. A thermal barrier that, when tested in conformance with CAN/ULC-S101, “Standard Method of Fire Endurance Tests of Building Construction and Materials”, will not exceed an average temperature rise of 140°C on its unexposed face after a period of 10 min satisfies this requirement.
