Analytical Flow adopted in EFA Laboratories

Point count analysis for

1000 points after gravimetric reduction.

Calculate asbestos content based on asbestos points counted and results of gravimetric reduction

End of analysis:

Calculate asbestos content with visual estimation.

Optional analysis using TEM

(transmission electron microscope): TEM can be used for samples with very low content of asbestos and/or small fiber size.

End of Analysis: Reported as None detected (guarantee asbestos <0.1%)

No asbestos detected

Determine asbestos fiber presence using PLM (Polarized Light Microscope).

(Identify asbestos fiber based on sign of elongation, extinction angle, dispersion staining color, pleochroism and morphology)

Asbestos ≧1% Asbestos <1%

Asbestos present

Visual estimation of asbestos content under PLM
