Abstract

This document specifies general principles for software development and signal transmission requirements of safety-related parts of machine-control systems (MCS) in earth-moving machinery and its equipment, as defined in ISO 6165:2022.

In addition, this document addresses the significant hazards as defined in ISO 12100:2010 related to the software embedded within the MCS. The significant hazards being addressed include incorrect machine control system output responses from machine control system inputs.

To cover all the relevant safety requirements for the products in its scope, this document is used in combination with ISO 19014-1:2026, ISO 19014-2:2026, ISO 19014-3:2026, and ISO 19014-5:2026.

Cybersecurity is out of the scope of this document.

NOTE            For guidance on cybersecurity, see an appropriate security standard.

This document is not applicable to earth-moving machinery manufactured before the date of its publication.
