Technical Analysis was provided by an independent, accrediting
laboratory. However, as sandstone is a natural material, these
figures of physical properties could vary, and purchasers and
users of ASI’s products should satisfy themselves as to the
physical properties of the sandstone product, and its suitability
for a particular application. Australian Sandstone Industries
accepts no responsibility for use of the Technical Analysis,
nor any liability whatsoever arising from its use. |
