Annotation of standard text ČSN EN 196-2 (722100):

Tato norma stanovuje metody pro chemický rozbor cementu. Tento dokument uvádí referenční metody a pro jisté případy alternativní metodu, která může být považována za ekvivalentní. V případě sporu se použije jen metoda referenční. Alternativní metoda rozboru cementu použitím rentgenfluorescenční spektrometrie (XRF) je popsána pro stanovení SiO2, Al2O3, Fe2O3, CaO, MgO, SO3, K2O, Na2O, TiO2, P2O5, Mn2O3, SrO, Cl a Br. Pokud je metoda správně kalibrována podle zavedených postupů a referenčních materiálů, je to metoda rovnocenná referenční metodě, ale není dosud ověřena pro prokázání shody nebo pro případy sporů. Metoda může být použita i na další prvky, pokud se provede odpovídající kalibrace. Tato metoda je založena na měření vzorku ve formě vytavené perly a analytické validaci použitím certifikovaných referenčních materiálů a kritérií přesnosti a správnosti. Metoda založená na měření lisovaných tablet nevyžíhaného vzorku může být také použita za předpokladu, že jsou dodržena stejná kritéria
