The Standard covers two types of wood fibre insulation on the basis of their material properties. The products covered by this standard are classified into Types, Classes and Grades based on their physical properties.

The wood fibre insulating boards shall not be used when the continuous service temperature is outside the range of -30 °C to +80 °C.

The testing and evaluation of a product against this Standard may require the use of materials and/or equipment that could be hazardous. This document does not purport to address all the health and safety aspects associated with its use.
