Действует
Optics and optical instruments - Test lenses for calibration of focimeters - Part 1: Test lenses for focimeters used for measuring spectacle lenses (ISO 9342-1:2005)
This part of ISO 9342 specifies requirements for test lenses for the calibration of focimeters that are used for
the measurement of spectacle form lenses.
NOTE It is accepted that other test lenses can also be used with powers within the given range, manufactured to the
same standard of accuracy and form, but different back vertex powers. However, only lenses with integer nominal powers,
as described in Annex A, can be used for the calibration of digitally-rounding focimeters.
Diese ÖNORM enthält Anforderungen an Testlinsen zur Kalibrierung von Geräten zur Bestimmung der Brennweite und otpischen Achse von Brillengläsern.
