This Standard specifies requirements for treated wood-based cellulose fibre intended for use as thermal insulation (Cellulose Fibre Insulation, CFI) in new and existing buildings within the temperature range of -60 °C to 90 °C.

This Standard describes general requirements for the material and additional requirements specific to the types of CFI.

The methods used in this Standard to measure and describe the properties of materials, products or assemblies in response to heat and flame under controlled laboratory conditions do not describe or appraise the fire hazard or fire risk of materials and products under actual fire conditions. Results of these tests are meant to be used as elements in a fire risk assessment that takes into account all of the factors that are pertinent to an assessment of the fire hazard of a particular end use.

The Second Edition, published in 2009, has been reaffirmed in 2015. The only addition to the text provides safety and warning markings in both English and French.
