Ophthalmic optics. Review of the test methods used to assess scratch and abrasion resistance of spectacle lenses1 Scope This document describes the most commonly used test methods considered in standardization work relating to scratch and abrasion resistance of plastic spectacle lenses along with their technical capacities and limitations. It includes the ISO test method for assessment of claims for basic abrasion resistance in ISO 8980 5. This document is intended to be of benefit to any future interest in ISO standardization on scratch and abrasion resistance

you can also improve your quality management systems by adopting best industry practices for conformance and qualification inspection and exhibiting compliance with BS EN IEC 61249-2-46 requirements

BS EN 15004-8 is helpful as the adoption of these requirements and specifications can aid in protecting safety personnel from hazards arising from:

In the case of finely dispersed undissolved matter

and stating the test report

PD IEC/TR 62510 on characteristics of electricity applies to:
