Le présent document ne s’applique pas:
—    aux verres de lunettes présentant des caractéristiques de transmission ou d’absorption spécifiques ayant fait l’objet d’une spécification pour raisons médicales;
—    aux produits auxquels s’appliquent des normes particulières relatives au facteur de transmission des équipements de protection individuelle; et
—    aux produits destinés à l’observation directe du soleil, par exemple pour observer une éclipse solaire.
NOTE 1        Par référence avec l’ISO 21987 et l’ISO 14889, le présent document s’applique aussi aux verres montés sur les lunettes.
NOTE 2        Les exigences optiques et géométriques sont fournies dans l’ISO 8980‑1 et l’ISO 8980‑2 pour les verres de lunettes finis non détourés et dans l’ISO 21987 pour les verres montés.

Očesna optika - Nebrušena zglajena stekla očal - 3. del: Specifikacije za prepustnost in preskusne metode (ISO 8980-3:2022)

Ta dokument določa zahteve za lastnosti prepustnosti nebrušenih in nenameščenih zglajenih stekel očal, vključno z s stekli, ki zmanjšujejo sončno sevanje. Ta dokument se ne uporablja za: – stekla očal s posebnimi lastnostmi prepustnosti ali apsorpcije, ki so predpisana iz zdravstvenih razlogov; – izdelke, za katere veljajo posebni standardi glede prepustnosti osebne zaščitne opreme, in – izdelke, namenjene neposrednemu opazovanju sonca, na primer opazovanju sončnega mrka. OPOMBA 1: Ob sklicevanju na standarda ISO 21987 in ISO 14889 se ta dokument uporablja tudi za stekla, nameščena v očala. OPOMBA 2: Optične in geometrijske zahteve so podane za nebrušena zglajena stekla očal iz standardov ISO 8980-1 in ISO 8980-2, ter za vgrajena stekla iz standarda ISO 21987.
