21/30432944 DC

This standard 21/30432944 DC BS EN 4876. Aerospace series. Environmental testing. Durability of the displays by general usage is classified in these ICS categories:

• 25.220.20 Surface treatment
• 19.040 Environmental testing
• 49.025.10 Steels
• 49.025.99 Other materials
• 49.060 Aerospace electric equipment and systems
• 31.120 Electronic display devices
• 49.095 Passenger and cabin equipment

This document provides a series of testing methods to determine the resistance of the digital display during general usage in an aircraft cabin. The document applies to any passive and interactive displays. It includes also dirt affinity and cleanability.

The testing methods include the determination of the durability of touchscreen surfaces, signing pads and general displays against human fingertip and hand abrasion, fingerprint and dirt affinity under the usage by humans as can occur during everyday operation inside an aircraft cabin. Additionally, the resistance against general abrasion, scratch and mar on the displays as well as the resistance study against the routine cleaning procedure conducted inside the aircraft is defined.

The test methods are also suitable to test the durability of a display surface against all low and high dynamic strains.
