CAN/ULC-S102.2-03

1. SCOPE 1.1 This method is applicable to the finished surface or covering of a floor extending to a maximum depth of 65 mm. It may also be applied to materials that cannot conveniently be tested in a ceiling mounted configuration. Thermoplastic and loose fill materials might be included in this category. 1.2 The primary purpose of the test 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 density and flame spread rate are recorded in this test. However, there is not necessarily a relationship between these two measurements. 1.4 It is the intent of this method 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.
