ISO 11986:2017提供了选择方法、制备样品以及测试隐形眼镜中防腐剂吸收和释放的一般程序。 注1:由于隐形眼镜在配戴过程中遇到矿物和有机沉积物时，其再现性明显困难，因此这些方法仅适用于新的和未使用的隐形眼镜。 注2:在有限体积的隐形眼镜盒中使用隐形眼镜消耗防腐剂可能会影响消毒性能。本文件不测量消毒性能。

ISO 11986:2017 provides general procedures for the selection of methods, preparation of samples, and the 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 document does not measure disinfection performance.
