TS EN 80416-2

TS EN 80416-2 addresses the basic principles for the form and use of arrows in graphical symbols used on equipment. It provides a general framework for how arrows are to be understood when they are used to indicate various elements, forces, functions or dimensions, with the aim of keeping their visual proportions and directional meaning consistent.

The technical role of arrow symbols

In graphical symbol systems, an arrow does more than simply show direction. In machinery, electrical and broader engineering documentation, arrows may indicate motion, force direction, flow, connection, or the direction in which a dimension is measured. For that reason, visual features such as form, arrowhead design, shaft proportion and placement are important to legibility. In general technical context, principles like these help symbols retain the same meaning across different types of equipment and documentation.

What this part covers

• The standard covers the basic principles and proportions for arrows.
• It addresses arrows used to indicate various elements, forces, functions or dimensions.
• As part of a wider graphical-symbol system, it is intended to be read together with TS EN 80416-1, which provides the broader framework.

The value of a standard like this is that it turns symbol design into a more consistent technical language rather than an intuitive choice. In practice, that supports clearer markings on equipment, more readable instructions, and more consistent technical drawings, while helping reduce ambiguity when the same arrow appears in different sectors or multilingual documents.
