Organization: ISO
Publication Date: 15 August 2006
Status: inactive
Page Count: 44
ICS Code (Ophthalmic equipment): 11.040.70
scope:

This part of ISO 18369 specifies the methods for measuring the physical and optical properties of contact lenses specified in ISO 18369-2, i.e. radius of curvature, back vertex power, diameter, thickness, inspection of edges, inclusions and surface imperfections, and determination of spectral and luminous transmittances. This part of ISO 18369 also specifies the equilibrating solution, standard saline solution, for testing of contact lenses.
