TS ISO 7573

TS ISO 7573 is the standard for the rules governing how parts lists are arranged in technical product documentation. In technical drawing practice, a parts list helps identify product components in a structured way so that the same item can be consistently referenced in production, procurement, and maintenance. The standard covers both manually prepared and computer-generated parts lists.

The technical role of a parts list

A parts list is a documentation tool that presents the identity, quantity, and relationship of the elements that make up a product or appear in a drawing. In technical drawing, the geometry carries the visual description, while the parts list supplies the textual and hierarchical information that completes it. That distinction matters because real assemblies often contain similar components, and correct work depends on identification as well as shape.

What this standard covers

The standard focuses on the minimum information requirements for parts lists, with the aim of ensuring that the list contains the information needed for production, procurement, or maintenance. In general engineering practice, such lists often include fields such as item numbers, names, and quantities. Here, however, the documented scope is about the rules for arranging the list rather than a specific fixed data model.

• Provides a framework for parts lists used together with technical drawings.
• Applies a common organisational logic to both manual and computer-generated lists.
• Supports readable and traceable component information for production, procurement, and maintenance.
