Performance of Asbestos Fibre Counting Laboratories by Transmission Electron Microscopy

摘要

In France, the owners of buildings have been obliged since February 1996 to ascertain whether asbestos has been incorporated into surfacing materials, insulation products or false ceilings. In certain circumstances, there is also a requirement to measure the airborne asbes- tos fibre concentration. Three years (1996-1998) of asbestos fibre count reporting are evalu- ated for the proficiency testing scheme organized in France to evaluate the performance of laboratories using an indirect-transfer transmission electron microscopy procedure to meas- ure the airborne asbestos fibre concentration.
