8、ries. Amendments This standard differs from DIN EN ISO 10322-1:2006-06 as follows: a) the scope has been extended to include all types of semi-finished single-vision and multifocal lens blanks; b) the requirements for the tolerance on surface cylindrical power have been changed (see Table 1); c) the

9、 description of the measuring method has been fundamentally revised; d) requirements for marking polarizing semi-finished spectacle lens blanks have been specified; e) a note has been included in 6.2 regarding the possible need for conversion to establish the tolerance values if the lens blank is me

10、asured with equipment calibrated for a different reference refractive index (see Annex B for tolerance value conversion table); f) the standard has been editorially updated, including the adaptation of the terms to the new edition of DIN EN ISO 13666; g) the revised text of ISO 10322-1:2016 has been
