Making measurements with light microscopes, scanning electron microscopes and transmission electron microscopes is described both with and without the use of automatic and semi-automatic image analysers. A system is established for calculating the number of fields of view that have to be analysed to achieve a specified accuracy, and methods are given for the estimation of uncertainties. Guidance is provided on sample preparation, practical microscopy and the choice of equipment for image analysis.<\/p>\n<p>This Part of BS 3406 does not cover the measurement of particle shape or the use of stereorological methods.<\/p>\n<p>This standard does not cover the measurement of asbestos fibres.
