Sound types, pitches, and repetition rates for alarms and horns.
In industrial automation and electrical engineering, clarity saves lives and prevents catastrophic machinery failures. When an operator glances at a control panel, they must instantly understand the status of the plant. is the international standard that establishes the coding principles for indicator lights, pushbuttons, and other human-machine interface (HMI) components.
IEC 60073 defines coding across three modalities: iec 60073 pdf
A Basic Safety Publication contains fundamental concepts, principles, and requirements for all safety aspects across a broad range of equipment and systems. This means that many other product-specific standards (so-called "group safety publications" and "product safety publications") refer to and rely on IEC 60073 for their own safety requirements concerning the man-machine interface. Therefore, compliance with IEC 60073 is often a prerequisite for compliance with other standards, making it a foundational document in the world of electrical and electronic equipment safety.
Color is the most effective means of attracting attention, but it must be used strictly according to the defined meanings: Safety Meaning Condition of Process/Equipment Emergency or Fault (e.g., E-Stop activated) Yellow Abnormal condition or transition state Green Normal condition; "Go" or circuit healthy Blue Requires specific operator action White No specific safety meaning; often used for auxiliary states Sound types, pitches, and repetition rates for alarms
is a fundamental international standard titled "Basic and safety principles for man-machine interface, marking and identification – Coding principles for indicators and actuators" . It provides a standardized framework for assigning meanings to visual, acoustic, and tactile signals to ensure the safe and efficient operation of equipment across various industries.
Typically used to draw attention to an abnormal but non-critical change of state. is the international standard that establishes the coding
: Using raised ridges or rough surfaces to distinguish between "Start" and "Stop" by touch alone.
: Encouraging the use of more than one sensory channel (e.g., visual and acoustic) to convey critical information. Core Coding Principles
