IEC 61747-40-4:2015

IEC 61747-40-4:2015 is the technical reference for liquid crystal display devices with a focus on mechanical testing of display cover glass for mobile devices using biaxial flexural strength, ring-on-ring methods. It is relevant when teams need a documented basis for product evaluation, test planning, or conformity assessment around cover glass performance under mechanical loading. For engineering, procurement, and laboratory workflows, IEC 61747-40-4:2015 helps align technical validation with a defined test approach, supporting more consistent review of durability-related requirements.

IEC 61747-40-4:2015 standard overview

The official title indicates a focused test method for assessing the biaxial flexural strength of display cover glass used in mobile devices. In practice, this type of document supports structured verification activities by giving laboratories and manufacturers a common technical basis for mechanical assessment. It is especially useful where documented evaluation, quality workflows, and engineering specification review depend on repeatable test execution and comparable results. For organizations handling display components, it can serve as a compliance reference during technical assessment and procurement review.

Applications of IEC 61747-40-4:2015

IEC 61747-40-4:2015 is typically used in product development, supplier qualification, and laboratory evaluation for mobile-device display cover glass. It may also support test planning for component validation, incoming quality control, and risk management activities where mechanical strength data are needed. Teams involved in design verification, certification preparation, or failure analysis can use it to structure testing workflows and document results in a consistent way. The standard is most relevant where display durability must be assessed against a defined ring-on-ring flexural method.

Why IEC 61747-40-4:2015 matters

This document matters because mechanical test consistency is essential for reliable product comparison and defensible conformity assessment. A clearly defined method helps reduce ambiguity in technical review, supports engineering validation, and improves confidence in procurement decisions for display cover glass. It can also assist with quality assurance by giving laboratories and manufacturers a repeatable basis for measuring strength-related performance. In regulated or customer-driven programs, using a recognized reference like IEC 61747-40-4:2015 can help streamline compliance workflows and reduce rework during technical acceptance.
