1. SCOPe 1.1
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. 1.2
This Standard describes general requirements for the material and
additional requirements specific to applications. The applications are
specified as Type 1 (dry) and Type 2 (spray applications). Type 1 application
is dry loose-fill cellulose insulation pneumatically applied in open spaces
(with slopes up to 4.5-in-12) and/or injected into enclosed cavities. Type 1
CFI may be also installed by poured application. Type 2 application is
cellulose insulation sprayed with water into any open space, or into any cavity
(regardless of slope) that will be closed later. 1.3
This Standard may require the use of materials and/or equipment that could
be hazardous. This document does not purport to address all the safety aspects
associated with its use. Anyone using this Standard has the responsibility to
consult the appropriate authorities and to establish appropriate health and
safety practices in conjunction with any existing applicable regulatory
requirements prior to its use. 1.4
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, products or assemblies 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 factors that are pertinent to an
assessment of the fire hazard of a particular end use.
