Bonded asbestos is in a form where asbestos fibres are held within another material (for example cement) but does not include friable asbestos. When dry, bonded asbestos materials cannot be crumbled, pulverised or reduced to powder by hand pressure.

Friable Asbestos is asbestos (whether or not contained in other material) that (a) is crumbly, dusty or powdery; or (b) when dry, can be crumbled, pulverised or reduced to powder by hand pressure. Examples of friable asbestos include, sprayed asbestos coating or insulation, asbestos lagging, loose asbestos and asbestos in its raw form.
