We examined the following sample(s) using Low Powered Stereomicroscopy followed by ‘Polarised Light Microscopy’ including
Dispersion Staining Techniques. The result(s) in this certificate relate(s) to the sample(s) as received.
GLOSSARY
CHRYSOTILE (WHITE ASBESTOS) - CROCIDOLITE (BLUE ASBESTOS) - AMOSITE (BROWN ASBESTOS) - TREMOLITE,
ANTHOPHYLLITE & ACTINOLITE (LESS COMMON ASBESTOS FIBRE TYPES) - SMF (SYNTHETIC MINERAL FIBRE)
Where non-asbestos fibres and the product type are listed, this is to help in the interpretation of results and are the opinion of the
analyst only. Where the sampling is not conducted by Dowdell & Associates Ltd, the information indicated is that supplied by the
client. Dowdell & Associates Ltd cannot be held responsible for sampling errors where the sample is taken by others. In analyzing
non-homogeneous Bulk Materials and Soils for the presence of Asbestos, inherent difficulties arise while using the ‘standard’
Stereomicroscopic / Polarised Light Microscope method in determining differences between those samples considered as containing
‘No Asbestos’, those containing ‘Trace’ asbestos and those samples considered as having asbestos present but in very low
concentrations. ’Trace’ Asbestos is defined in the ‘AS 4964 (2004) – Method for the Qualitative Identification of Asbestos in Bulk
Materials’, which is the most current of methods available for this type of analysis. Dowdell & Associates Ltd, while making every effort
to minimise such difficulties, takes no responsibility for the misidentification of such samples and the subsequent actions taken by the
client as a result of such analyses. A in-house subsampling method based on Western Australia guidelines is used for soil samples
recieved above 150 grams.
