IEC 62715-6-42:2026 pdf download,Flexible displays – Part 6-42: Mechanical test methods – Flattening force measurement methods for rollable display devices.

IEC 62715-6-42:2026 specifies standardized measurement conditions and test methods for determining the flattening force of rollable display devices when they are extended into a flat state. It applies to flexible display panels and modules that can be rolled along either one axis or two axes.

The standard provides a consistent approach for evaluating the mechanical force required to overcome the display’s natural curvature, rolling memory, bending stiffness, and structural resistance. It is intended to improve comparability among products, materials, designs, and manufacturers during research, development, production, quality control, and reliability assessment.

The document defines the relevant test setup, specimen condition, measurement configuration, loading or flattening procedure, force-measuring equipment, and data-recording principles. It also establishes how the device should be positioned and controlled during testing so that results are repeatable and representative of actual use. Depending on the device structure, the method can be applied to displays rolled in a single direction or displays capable of double-axis rolling.

Measured flattening force can help engineers evaluate user operation, deployment mechanisms, panel durability, structural design, and long-term performance. The results may also support product specifications, design comparisons, process optimization, acceptance criteria, and failure analysis. Overall, the standard creates a common mechanical-test framework for assessing how easily and reliably rollable displays can be flattened without compromising their function or structural integrity.
