| Published By | Publication Date | Number of Pages |
| ISO | 1990-12 | 12 |
La présente Norme internationale spécifie une méthode d'essai pour la résistance des verres optiques bruts à l'attaque par des solutions aqueuses de détergent contenant du phosphate alcalin, à 50 °C ainsi qu'une classification des verres d'optique conformément à leur résistance aux solutions aqueuses de détergent contenant du phosphate (résistance au phosphate) déterminée à l'aide de cette méthode. La présente Norme internationale est applicable aux échantillons de tous verres d'optique bruts.
NOTE 1 La méthode d'essai peut également être utilisée pour d'autres types de verres.
