PR NF EN ISO 19014-2, E58-083-2PR (03/2024)

This document specifies general principles for developing and evaluating the Machine Performance Level Achieved (MPLa) of Safety Control Systems (SCS) using components powered by all energy sources (e.g. electronic, electrical, hydraulic, mechanical) used in earth-moving machines and their equipment, as defined in ISO 6165. The principles of this document apply to machine control systems (MCS) that control the movement of a machine or mitigate a dangerous phenomenon; these systems are evaluated to verify that the machine performance level (MPLr) requirements comply with ISO 19014-1 or ISO/TS 19014-5. The following systems are excluded from the scope of this document: — knowledge systems having no impact on the movement of the craft (e.g. cameras and radar detectors); — firefighting systems, unless activation of the system interferes with or activates another SCS. Other systems or components for which failures could be noticed by the operator (e.g. windshield wipers, headlights, cabin lighting, etc.) or those which serve primarily to protect property are excluded from the this document. Audible warning devices are excluded from diagnostic coverage requirements. Additionally, this document addresses significant hazards as defined in ISO 12100 mitigated by hardware components in the SCS. This document is not applicable to earth-moving machinery manufactured before the date of its publication.
