The scope of this document describes the relevant machinery and the extent of the hazard, hazardous situation or hazardous event.

This document is a Type C standard described by ISO 12100.2010.When the requirements of Type C standards are different from those of Type A or Type B standards, for

For machines designed and manufactured in accordance with the requirements of this Class C Standard, the requirements of this Class C Standard take precedence over the requirements of other standards.

With the widespread use of electronic equipment in the working areas of earthmoving machinery and construction machinery, it is necessary to ensure that the machinery has sufficient resistance to electromagnetic disturbances.

The resulting internal electromagnetic interference (machine interference) is lower than the immunity of the individual subsystems.

The electrical disturbances and high-frequency disturbances described in this document refer to electromagnetic effects due to technical application (artificial effects). These electromagnetic effects are
