TS 2575 EN 60073

TS 2575 EN 60073 addresses coding principles for indication devices, marking and actuators in the man-machine interface. It sets out basic and safety principles for assigning specific meanings to visual, acoustic and tactile indications so that control states can be recognised more quickly and equipment can be monitored and managed more safely.

Why coding matters in the man-machine interface

In technical systems, an operator must interpret status as well as operate controls. Consistent use of colours, symbols, illuminated indicators, audible signals and tactile cues helps reduce ambiguity during operation, maintenance and fault diagnosis. In general engineering practice, the aim is not merely to label parts, but to create a stable meaning system so that the same kind of indication conveys the same type of information across equipment and processes.

Types of indications covered in the general concept

• Visual indications: lights, colours, symbols and markings that can be recognised at a glance
• Acoustic indications: audible warnings and signals used to distinguish conditions
• Tactile indications: physical feedback that can be identified by touch
• General coding principles that help operators quickly recognise control conditions and actuator positions

The standard is concerned with the general principles behind these meanings rather than with a single machine category. That makes it relevant to industrial control panels, electrical equipment and broader machine interfaces where clear identification supports safe monitoring, proper operation and maintenance.

This listing represents the Turkish adoption of EN 60073. Its technical subject is the structured use of indications and identification in machine interfaces, providing a common framework for how different sensory signals should be interpreted.
