OTHER MINERAL FIBERS IN ENVIRONMENTAL AIR

ANALYSIS METHODS

Detection and counting of resistant ceramic fibers, glass wool or rock wool in the sampling of environmental air through an observation by transmission electron microscope (TEM) or scanning electron microscope (SEM)

TECHNIQUES AND MATERIALS EMPLOYED

TEM and/or SEM  

NATURE OF THE RESULTS

Results are quantitative: number of fibers observed and analytical sensibility.

The analytical sensibility can be measured if the volume of the sampling is being communicated.

ESTIMATED TIME

Day 1, day 3 or day 5

SAMPLING

Sampling cassettes labelled and packed in waterproof zip lock bags

NORM and REFERENCE

Internal method, adapted from the Norm NF X 43-050
