Hard coal — Size analysis by sieving

ISO 1953:2015 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 μm. A guide to sampling is given in Annex A. This International Standard is applicable to all hard coals. It is not applicable to coke or other manufactured fuels. In the case of pulverized coal which has been ground so that a high proportion passes through the test sieve of smallest aperture size, the methods described in this International Standard will determine only the percentage oversize.

Houille — Analyse granulométrique par tamisage

Črni premog - Določanje zrnatosti s sejalno analizo

Ta mednarodni standard določa referenčne metode za sejalno analizo premoga z ročnim sejanjem (mokrim ali suhim) pri uporabi preskusnih sejalnikov z velikostjo odprtine sita od 125 mm do 45 μm. Navodila za takšno vzorčenje so podana v dodatku A.
Ta mednarodni standard se uporablja za vse vrste črnega premoga. Ne uporablja se za koks ali druga proizvedena goriva.
V primeru premoga v prahu, ki je bil zmlet tako, da najmanjša velikost odprtine preskusnega sita prepusti velik delež premoga, metode, opisane v tem mednarodnem standardu, določajo le nadmerni odstotni delež.
