| Subject of the standard: | Tato medzinarodna norma specifikuje dve metody stanovenia objemovej hmotnosti zrnitych ziaruvzdornych materialov (hustoty zrn) s velkostou zrn nad 2 mm. Metoda 1: ortutova metoda s vakuom; Metoda 2: vodna absorpcna metoda. Metoda 1 sa povazuje za rozhodujucu metodu. V zavislosti od povahy skusaneho materialu mozu mat tieto dve metody rozdielne vysledky. Preto ma byt kazda stanovena hodnota objemovej hmotnosti doplnena udajom, ktora metoda sa pouzila, alebo ktora ma byt pouzita v spornom pripade. |
