适用范围：This part of ISO 8980 specifies the requirement and test method for spectacle lens surfaces that are claimedto provide a basic level of abrasion resistance including those with coatings.A lens claimed to be abrasion-resistant shall meet the requirements on both front and back surfaces.Lens powers and surface form is restricted for testing, however test results are applicable to claims for lensesand lens surfaces with identical properties other than the lens power or surface radius.This part of ISO 8980 does not attempt to define the properties of lens surfaces with abrasion resistancebetter than the following defined criteria.
