This part of IEC 61747 is a mechanical performance testing procedure for cover glass used in electronic flat panel displays in mobile devices. This document focuses on the measurement of surface fracture load after flaw introduction via grit particle abrasion. After abrasion, the retained surface fracture load is measured with the method documented in IEC 61747-40-4.
