About This Item
IEC 61747-40-3:2015 defines a focused mechanical test method for display cover glass used in mobile devices, specifically the biaxial flexural energy to failure ball drop approach. For engineering, testing, and procurement teams, it provides a technical reference for evaluating how cover glass behaves under impact-related stress and for aligning documented evaluation with a consistent testing workflow. The document is relevant when comparing material performance, supporting technical review, or preparing conformity assessment evidence for display component qualification.
Overview of IEC 61747-40-3:2015
This technical document is part of the IEC 61747 series and addresses a narrow but important aspect of display robustness: mechanical testing of mobile device cover glass. IEC 61747-40-3:2015 is intended to support laboratory evaluation of failure resistance using a ball drop-related biaxial flexural energy to failure method. Its scope is especially useful when teams need repeatable test conditions, structured reporting, and a clear reference for product evaluation, engineering documentation, and quality workflows tied to display protection materials.
Compliance applications of IEC 61747-40-3:2015
Organizations may use IEC 61747-40-3:2015 during material qualification, supplier comparison, and verification activities for cover glass intended for mobile devices. It can support test planning in laboratories, internal reliability assessments, and procurement reviews where mechanical performance evidence is required. The standard is also relevant in technical assessment and regulatory preparation when a documented method is needed to show how impact-related failure characteristics are measured and compared consistently across products, batches, or design iterations.
Importance of compliance with IEC 61747-40-3:2015
Using IEC 61747-40-3:2015 helps improve consistency in mechanical testing and reduces ambiguity when evaluating cover glass performance. That consistency supports risk management, quality assurance, and conformity assessment preparation by giving engineering and compliance teams a shared reference for test execution and reporting. It can also assist procurement decisions by making supplier claims easier to review against a defined testing basis. In practice, this helps organizations strengthen technical validation and reduce uncertainty in product qualification workflows.
