TS EN ISO 10135

TS EN ISO 10135 is a GPS standard for drawing indications of moulded parts in technical product documentation. It defines rules for expressing requirements for moulded parts on drawings and technical documents, and it specifies the proportions and dimensions of the graphical symbols used for that representation. In practical terms, it helps make product-geometry information read consistently across design, manufacture, and inspection.

Why drawing indications matter for moulded parts

Moulded parts are components formed by processes such as injection moulding, casting, compression moulding, or related shaping methods. For these parts, a technical drawing must communicate more than the external form: parting-line logic, orientation, datum references, and other functional features may also need to be shown in a controlled and consistent way. In the GPS context, standardised indications reduce ambiguity and support a common interpretation of the product definition.

What this standard specifies

The standard covers the rules and conventions for indicating requirements for moulded parts in technical product documentation, together with the proportions and dimensions of the graphical symbols used in that representation. It therefore provides a specific notation framework for documents rather than a general drawing philosophy. As general technical context, this kind of notation helps engineers describe the same part in a way that aligns design intent, manufacturing constraints, and inspection needs.

It is especially useful where moulded components require symbolic communication on engineering drawings, because the notation can make manufacturing-related characteristics understandable alongside dimensional information.
