Standard Method of Test for Surface Burning Characteristics of Flooring, Floor Coverings, and Miscellaneous Materials and Assemblies

This Standard is applicable to the finished surface or covering of a floor extending to a maximum depth of 65 mm. This method is also applicable to the following:
Materials which cannot be tested as described in Clause 1.1 of CAN/ULC-S102, Standard Method of Test for Surface Burning Characteristics of Building Materials and Assemblies, without the use of supporting material that is not representative of the intended installation;
Materials which, when tested in the manner described in Clause 1.1 of CAN/ULC-S102,
Standard Method of Test for Surface Burning Characteristics of Building Materials and Assemblies, melts or drips, or otherwise disintegrates and continues to burn on the floor of the test chamber;
Materials designed for use in a relatively horizontal position with only its top surface exposed to air; or Thermoplastic materials.

The primary purpose of this Standard is to determine the comparative burning characteristics of the material or assembly under test by evaluating the flame spread over its surface when exposed to a test fire and thus establish a basis on which surface burning characteristics of different materials or assemblies may be compared, without specific considerations of all the end-use parameters that might affect these characteristics.
