TS 8611

TS 8611 is a standard on how circuit diagrams used in electrotechnology are to be prepared, with its provisions linked to the general rules given in TS 8294. It provides guidance for drafting practices that aim to keep electrical documentation consistent and easy to interpret, while excluding the rules for marking equipment connection terminals.

The technical role of circuit diagrams

Circuit diagrams show electrical relationships rather than the physical layout of components. For that reason, consistent symbol use, orderly line presentation, and clear references are important for reading, maintenance, review, and project documentation. In electrotechnical documentation, drafting rules help different teams interpret the same system in the same way and keep related documents aligned.

Scope and boundary of this standard

• Applies to circuit diagrams used in electrotechnology.
• Works together with the general rules given in TS 8294.
• Does not cover rules for marking equipment connection terminals.
• Referenced as equivalent to IEC 113-4:1975.
• Withdrawn and replaced by TS EN 61082-2.

In current practice, documents of this kind remain useful as a technical reference for understanding schematic representation. Symbol conventions, line arrangement, and diagram structure are core elements of electrical documentation, but this standard does not define the whole documentation family; it frames the preparation approach for circuit diagrams specifically.
