<abstract displayLabel="Summary">A microscope eyepiece graticule has been designed specifically to help in the counting of respirable fibrous dust. This is now in use in a number of laboratories and has been found to have several advantages over conventional designs, in particular when determining the length and diameter of fibres</abstract>
