BS EN 1021‑1 and BS 5651 provide suitable methods of cleansing or wetting

Selectivity is the ability of the receiver to discriminate between wanted and unwanted input signals

This standard includes two types of vibration tests: the vibration response test and the vibration endurance test

Ergonomics of human-system interaction - User performance test methods for electronic visual displays Ingestion-build-44680 If such an observation is1 Scope This part of ISO 9241 provides guidance for assessing the visual ergonomics of display technologies with user performance test methods (as opposed to the optical test methods given in ISO 9241 305). Its use will help to ensure that, for a given context of use, a display meets minimum visual ergonomics requirements. It covers only visual attributes and does not address the ergonomics or usability of the whole product that houses a visual
