Scope:

The purpose of this test method is to determine the contribution to fire growth of protective coverings over foamed plastic when tested in a Full-Scale Room Test in accordance with CAN/ULC-9705, except as modified in this Standard.

 

This test method measures the time to flashover under specified test conditions. 

 

This test method is not intended to determine the fire resistance rating of wall or ceiling assemblies lined with foamed plastic and a protective covering.  In addition, this test method does not investigate the toxic hazard posed by the products of combustion.

 

This test method provides for classifications of 10 min and 20 min which are not equivalent to classifications prescribed in CAN/ULC-S124.

 

NOTE: See Appendix A1 for further background information on the differences between CAN/ULC-S145 and CAN/ULC-S124.

 

The exposure test, as described in this Standard, is not intended to be representative of all fire conditions.  It is likely that conditions will vary with changes in the amount, nature and distribution of fire loading, ventilation, size and configuration of the assembly installed.  These requirements provide a relative measure of the fire performance of comparable assemblies under these specified fire exposure conditions.

 

This Standard is used to measure and describe the response of materials, products or assemblies to heat and flame under controlled conditions.

 

This Standard includes classifications based on the use of a Full-Scale Room Test in accordance with CAN/ULC-9705 but as defined in this Standard.

 

It is the intent that classifications shall register performance during a period of exposure and shall not be construed as determining suitability for use after fire exposure.

Project need:

To develop a room corner test standard as a means of evaluating products that do not fall within the Scope and cannot be evaluated under the current requirements of CAN/ULC-S124. This new standard would be considered an extension to CAN/ULC-S124.
