What is ISO 24550-Accessible design for indicator lights about?
ISO 24550 discusses accessible design in ergonomics. ISO 24550 is an international standard on design requirements for indicator lights that assists to enhance the efficiency of the indicator lights.
ISO 24550 specifies design requirements and recommendations for indicator lights, mainly LED sourced, on consumer products for use by older people and people with visual disabilities.
Under ISO 24550 indicator lights include those that inform users visually about the conditions, changes in functional status and settings, and malfunction of products. They convey information by light on/off, time-modulated intensity, blinking, color, luminance level, and layout.
ISO 24550 addresses household and home appliances.
Note 1: ISO 24550 excludes electronic displays presenting characters and graphics, machinery, and appliances in special use for professional, technical, and industrial applications.
Note 2: ISO 24550 does not consider the needs of persons who are blind.
Who is ISO 24550- Accessible design for indicator lights for?
ISO 24550 on accessible design for indicator lights is relevant to:
- Indicator light manufacturers
- Indicator light designers
- Indicator light dealers and suppliers
Why should you use ISO 24550- Accessible design for indicator lights?
Indicator lights of consumer products provide important data to use products properly. Although their importance is recognized widely, many difficulties exist about indicator lights such as insufficient on/off visibility, unclear implications of lighting modes, and discomforting glare are reported by users, particularly by older persons or persons with visual disabilities. These claims result from the lack of a relevant standard related to indicator lights design.
ISO 24550 provides you with the design requirements, modes of lighting conditions, color, luminance, size, and marking of the indicator light to build efficient indicator lights on consumer products.
The requirements and recommendations provided by ISO 24550 assist you to improve the quality performance of the indicator light and help to identify the errors as it happens.
