Testing Process

Asbestos Laboratory Services are accredited to ISO/IEC 17025 to test samples of suspect materials using Polarised Light Microscopy (PLM) against the HSE technical manual HSG248.

Every Sample received is prepared by the analyst using visual analysis under a stereo microscope. The morphology, appearance and fibre colour is recorded. Any suspect fibre is mounted on a glass side in a Refractive Index (RI) fluid that is perceived to be the nearest match to the RI of the suspect fibre.

The sample is then mounted and viewed through the Polorised Light Microscope (PLM) the following checks are then performed by the analyst:


  • Pleochroism
  • Birefringence
  • Extinction
  • Sign of Elongation
  • Dispersion Staining
