Hard coal. Size analysis by sievingWhat is ISO 1953 Hard coal Size analysis by sieving about? ISO 1953 specifies reference methods for the size analysis of coal by manual sieving (wet or dry), using test sieves of aperture sizes between 125 mm and 45 m. A guide to sampling is given in Annex A. ISO 1953 is applicable to all hard coals. In the case of pulverized coal which has been ground so that a high proportion passes through the test sieve of the smallest aperture size, the methods
