Draft summary

This document specifies general principles for the development and evaluation of the machine performance level achieved (MPLa) of safety-control systems (SCS) using components powered by all energy sources (e.g.electrical, hydraulic, mechanical) used in earth-moving machinery and its equipment, as defined in ISO 6165:2022. The principles of this document apply to machine control systems (MCS) that control machine motion or mitigate a hazard; such systems are assessed for machine performance level required (MPLr) per ISO 19014-1:202X or ISO 19014-5:202X. Requirements for the application of functional safety throughout the software development lifecyle are addressed in ISO 19014-4:202X. This document excludes the following systems: This document also excludes other systems or components where the operator would be aware of failure (e.g. windscreen wipers, head lights), or are primarily used to protect property. Audible warnings are excluded from the requirements of diagnostic coverage. In addition, this document addresses the significant hazards as defined in ISO 12100:2010 mitigated by the hardware components within the SCS. This document is not applicable to EMM manufactured before the date of its publication.
