Le présent document constitue un amendement à la norme NF ISO 12123, de mars 1996. Cet amendement concerne les points suivants :- paragraphe 2.3 définition de la concentration : zone d'essai = 5 % de la surface totale (à la place de 4 %) ;- paragraphe 6.2 mode opératoire : diamètre des inclusions d'au moins 0,030 mm (à la place de 0,063 mm).
ISO 12123:2010 gives rules for the specification of raw optical glass. It serves as a complement to ISO 10110, which provides rules specifying finished optical elements. Since raw optical glass may be quite different in shape and size from the optical elements, its specification also differs from that of optical elements. ISO 12123:2010 provides guidelines for the essential specification characteristics of raw optical glass in order to improve communication between glass suppliers and optical element manufacturers. For specific applications (e.g. lasers, the infrared spectral range) specifications based on this International Standard will have to be supplemented.
