Scope

This part of ISO 8980 specifies the requirements and test method for spectacles lens surfaces that are claimed to provide a basic level of abrasion resistance including those with coatings.A lens claimed to be abrasion-resistance 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 lenses and 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 resistance better than the following defined criteria.
