1. All values are approximate.
2. Maximum allowable thickness at 1,000°F (538°C): Type I-HP - 8.5" (216mm); Type II-HP - 6"(152mm).
3. The surface burning characteristics of these products have been determined in accordance with UL 723, ASTM E84 or CAN/ULC-S102. These should be used to measure and describe the properties of materials, products or assemblies in response to heat and flame under controlled laboratory conditions and should not be used to describe or appraise the fire hazard or fire risk of materials, products or assemblies under actual fire conditions. However, results of this test may be used as elements of a fire risk assessment which takes into account all of the factors which are pertinent to an assessment of the fire hazard of a particular end use. Values are reported to the nearest 5 rating.
4. Preproduction qualification testing complete and on file. Chemical analysis of each production lot testing required for total conformance.
