EN81-70:2018 is a European standard that specifically addresses the requirements for the design and construction of control devices, including keyboards, used in elevator systems. This standard establishes guidelines and regulations aimed at ensuring the safety, accessibility, and usability of elevator control interfaces. EN81-70:2018 specifies various aspects such as the layout, labeling, size, color, and operation of buttons and other input elements on elevator keyboards. Compliance with this standard is crucial for elevator manufacturers and building owners to meet legal requirements, enhance passenger safety, and provide a user-friendly experience within elevator systems.

EN81-70:2018 specifies various requirements for buttons and other input elements on elevator keyboards. These requirements ensure consistent and standardized design, promoting safety, accessibility, and usability within elevator systems. Here is a detailed explanation of the key requirements:

1. Layout: The standard defines the arrangement of buttons on the elevator keyboard, considering factors such as logical grouping, intuitive navigation, and ergonomic considerations. The layout should facilitate easy identification and operation of different functions.

2. Labeling: Each button must have clear and legible labeling, indicating its respective function or destination. The labels should be easily readable, using appropriate fonts, sizes, and colors to ensure visibility and understanding.

3. Size: The standard specifies the minimum size for buttons to ensure ease of use, especially for individuals with varying dexterity or visual impairments. Buttons should be large enough to be easily discernible and operable, avoiding accidental inputs.

4. Color: The standard defines color requirements for buttons, considering contrast and visibility. Colors should be chosen to ensure clear differentiation between buttons and labels, aiding users in identifying and selecting the desired options.

5. Operation: Buttons should be designed to provide clear tactile feedback, allowing users to feel and confirm button presses. The standard may specify force requirements or travel distances for button activation, ensuring reliable and intentional inputs.

6. Emergency Buttons: EN81-70:2018 also outlines specific requirements for emergency buttons on elevator keyboards. These buttons must have distinct characteristics, such as being visually prominent, easily accessible, and identifiable by touch, to facilitate immediate response in emergency situations.

Overall, compliance with EN81-70:2018 ensures that the buttons and input elements on elevator keyboards are designed to be user-friendly, intuitive, and accessible for all users. Adhering to these requirements enhances the overall safety, efficiency, and user experience within elevator systems.
