UNE-EN ISO 19014-2:2023

This part of ISO 19014 specifies general principles for the development and evaluation of the achieved machine performance level (MPLa) of safety-control systems (SCS) using components powered by all energy sources used in earth-moving machinery and its equipment, as defined in ISO 6165. This document is used in conjunction with the other parts in the series.

ISO 19014 is to be used in conjunction with ISO 13849 when applied to Earth Moving Machinery (EMM) and supersedes ISO 15998. Where specific requirements are given in ISO 19014, they take precedence over the requirements in ISO 13849.

The principles of this standard apply to control systems that control machine motion or mitigate a hazard. Such systems are assessed for performance level requirements per ISO 19014-1 or ISO/TS 19014-5.

Excluded from the scope of ISO 19014 are the following systems:

Awareness systems that do not impact machine motion (e.g., cameras and radar detectors)

Fire suppression systems, unless the activation of the system interferes with, or activates, another SCS.

Other systems or components whereby the operator would be aware of failure (e.g., windscreen wipers, head lights, etc.), or are primarily used to protect property, are excluded from this document. Audible warnings are excluded from the requirements of diagnostic coverage. Refer to Clause 7.4.3.
