Why should you use BS IEC 61747-40-3 - Biaxial flexural energy to failure of display cover glass ?
Mobile electronic devices have become increasingly sophisticated and often incorporate displays for the purposes of user interface and viewing. Such displays commonly incorporate a transparent cover glass, which aids in protecting the display against the introduction of damage through routine device transport and use, as well as occasional or accidental misuse.  
BS IEC 61747-40-3 provides you with mechanical testing procedures for cover glasses utilized in such applications. Such glasses can be strengthened, for example via an ion-exchange process, which acts to increase mechanical strength through the introduction of a surface compressive layer.
If you are a manufacturer of display cover glass for mobile devices, BS IEC 61747-40-3 can ensure your products offer the minimum required resistance to abrasion, for optimal performance and durability of the electronic devices. Conformity to the testing procedures of BS IEC 61747-40-3 can help demonstrate the durability and reliability of your products.
