CAN/ULC-S102.2-07

1. SCOPE 1.1 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: A Materials which cannot be tested as described in Clause 1.1 of CAN/ULC-S102 without the use of supporting material that is not representative of the intended installation; B Materials which, when tested in the manner described in Clause 1.1 of CAN/ULC-S102, melt and drip, or otherwise disintegrate and continue to burn on the floor of the test chamber; C Materials that are designed for use in a relatively horizontal position with only its top surface exposed to air; or D Thermoplastic materials. 1.2 The primary purpose of the 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. 1.3 Smoke Developed Value (SDV) and Flame Spread Value (FSV) are recorded in this Standard. There is not necessarily, however, a relationship between these two measurements. 1.4 It is the intent of this Standard to register performance during the period of exposure, and not to determine suitability for use after the test exposure. 1.5 This method does not establish standards of performance for specific applications. It is a means of evaluating the response of materials, products or assemblies to a particular fire exposure under controlled laboratory conditions.
