DANSK DSF/FPREN ISO 11986 PDF

This International Standard provides general procedures for the selection of methods, preparation of samples, and conduct of testing for the uptake and release of preservatives from contact lenses. NOTE 1 – Due to the manifest difficulties of reproducibility when coating contact lenses with mineral and organic deposits encountered during lens wear, these methods are only applicable to new and unused contact lenses. NOTE 2 – Preservative depletion by a contact lens in the limited volume of a lens case could compromise disinfection performance. This International Standard does not measure disinfection performance.
