Annotation of standard text ČSN EN ISO 6506-3 (420359):

Norma ČSN EN ISO 6506-3 specifikuje metodu kalibrace referenčních destiček, jejichž použití se vyžaduje k nepřímému ověřování zkušebních strojů pro měření tvrdosti podle Brinella ve smyslu ISO 6506-2. Podrobně uvádí všechny podmínky, které je nutno dodržet při výrobě referenčních tvrdoměrných destiček, a které zároveň slouží k ověřování jejich správnosti. Dále popisuje všechny požadavky, kterým musí vyhovět kalibrační přístroj a všechny jeho složky, včetně vnikacího tělesa, měřicího systému a zkušebního cyklu. Popisuje postup kalibrace a způsob stanovení homogenity tvrdosti. V závěrečných kapitolách popisuje způsob označování destiček a podmínky platnosti jejich kalibrace. Příloha je věnována problematice stanovení nejistoty průměrné hodnoty tvrdosti destiček
