TS 6709

TS 6709 is a standard on how item lists are arranged in technical drawings, helping technical documentation present product-identification information in a consistent way. In technical drawing, an item list brings together the components of a product, assembly, or subassembly with identifying data such as position number, name, and quantity. The issue is therefore not just layout; it is the clear linkage between the drawing and the parts that must be manufactured, assembled, or supplied.

The role of an item list in technical drawing

In general engineering documentation, item lists help users identify the components of an assembly at a glance. A well-structured list supports the relationship between balloon numbers, position marks, and component descriptions on the drawing. In machine design, assembly drawings, and service documentation for complex products, this is one of the key information layers that reduces the risk of selecting the wrong part.

What this standard focuses on

The scope of TS 6709 is the arrangement rules for item lists in technical drawings. In other words, it addresses how item-list information is ordered and presented on the drawing. Rules of this kind help different teams read the same technical information consistently and support a more uniform structure for drawing documents.

This edition is published as equivalent to ISO 7573:1983 and is now withdrawn. Even so, the subject remains part of core engineering knowledge in technical drawing, assembly documentation, and the identification of product components.
