This part of ISO xxx is applicable to tractors, self-propelled ride-on machines, and mounted / semi-mounted or trailed machines used in agriculture. The standard specifies general requirements that relate to the protection and safety of operators and by standers on machines with on-board voltages in the range of 50-1000 Vac and 75-1500 Vdc. This applies to electrical equipment and parts of the electrical equipment on such machines. Supporting electrical equipment standards like IEC 60204-1 and ISO 6469 are to be considered.

In addition this part of ISO xxx defines requirements that can apply to the electrical equipment of ag tractors and machines. Example areas may include, but are not exclusive to:
- Protection against electric shock
- Wiring Practices
- Marking Warning Signs - Safety symbols*
- Operator manual considerations

* New safety symbols required would be directed to SC19/TC23/SC14 for consideration.
