BS IEC 62715-6-1-2018 PDF

Full title and description

STB BS IEC 62715-6-1:2018 — Flexible display devices. Mechanical test methods — Deformation tests. This British-adopted version reproduces IEC 62715-6-1:2018, which defines standardized mechanical deformation test methods (bending, rolling, twisting, stretching) for flexible display panels and modules such as LCD, e-paper and OLED.

Abstract

This standard specifies test apparatus, procedures and reporting requirements to evaluate the mechanical stability and deformation resistance of flexible display devices. It includes static and cyclic bending, rolling, torsion and tension tests, plus evaluation criteria for visual and measured image quality after mechanical stress. The 2018 edition is a technical revision that expands bending tests and provides more detailed procedures.

Scope

This part of IEC 62715 applies to flexible display panels and modules (including LCD, EPD/e-paper and OLED) and defines mechanical deformation test methods to assess their resistance to bending, rolling, twisting and stretching in typical use, transport and handling. Tests address both specimen conditioning and post-test image-quality evaluation requirements.

Key topics and requirements

• Definitions of specimen and test-piece preparation, and required atmospheric/test conditioning.
• Static bending tests (displacement/deflection, fixture geometry and acceptance criteria).
• Cyclic (fatigue) bending tests — apparatus, cycle counts, speed and reporting.
• Rolling and rollability tests to assess curvature endurance and recoverability.
• Torsion (twisting) and tension (stretching) tests for mechanical resilience.
• Evaluation criteria: visual inspection and measured image-quality checks (luminance, chromaticity, uniformity, line/point defects) and reporting requirements.
• Detailed test procedure descriptions and mandatory reporting elements to ensure repeatability and comparability between laboratories.

Typical use and users

Primary users are display module manufacturers, materials suppliers, R&D and reliability laboratories, qualification and quality-assurance teams, and test houses performing conformance and durability testing of flexible displays. Product engineers and standards/ compliance specialists use the standard to define mechanical test protocols for design verification and supplier acceptance.

Related standards

IEC 62715 is a multipart series covering flexible display devices. This part (6-1) supersedes the 2014 edition. Related parts include: IEC 62715-6-2 (Environmental testing methods, 2017), IEC 62715-6-3 (Impact and hardness tests, 2020), and later mechanical-method addenda such as IEC/TR 62715-6-21 (foldable durability) and IEC 62715-6-22 (crease and waviness measurement). Users often apply this part together with other IEC 62715 parts and relevant OLED/LCD environmental standards (for example IEC 62341 series).

FAQ

Q: What is this standard?

A: It is the British-adopted version of IEC 62715-6-1:2018, titled "Flexible display devices — Part 6-1: Mechanical test methods — Deformation tests", which standardizes mechanical deformation test methods for flexible displays.

Q: What does it cover?

A: It covers apparatus, procedures and reporting for deformation tests — static and cyclic bending, rolling, torsion and tension — and sets out evaluation criteria for post-test image quality and mechanical damage.

Q: Who typically uses it?

A: Display manufacturers, component and materials suppliers, R&D and reliability labs, QA teams and independent test houses use it to qualify flexible display designs and verify mechanical durability.

Q: Is it current or superseded?

A: The 2018 edition (Edition 2.0) replaces the 2014 edition. The IEC record lists the 2018 edition as the current published edition (stability date noted by IEC through 2030); the British-adopted text is published by BSI (April 2018).

Q: Is it part of a series?

A: Yes — IEC 62715 is a multipart series for flexible display devices. Part 6 contains mechanical test methods in multiple subparts (for example 6-1 deformation tests, 6-2 environmental tests, 6-3 impact/hardness and further specialized test-method documents).

Q: What are the key keywords?

A: Flexible display, deformation, bending, rolling, torsion, tension, cyclic testing, mechanical stability, display module qualification.
