AS ISO 19014.4:2022 PDF
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 (EMM) and its equipment, as defined in ISO 6165. In addition, this document addresses the significant hazards as defined in ISO 12100 related to the software embedded within the machine control system. The significant hazards being addressed are the incorrect machine control system output responses from machine control system inputs.
This document addresses systems comprising any combination of electrical, electronic, and programmable electronic components [electrical/electronic/programmable electronic systems (E/E/PES)] used for functional safety in earth-moving machinery.
The structure of safety standards in the field of machinery is as follows.
Type-A standards (basis standards) give basic concepts, principles for design, and general aspects that can be applied to machinery.
Type-B standards (generic safety standards) deal with one or more safety aspect(s), or one or more type(s) of safeguards that can be used across a wide range of machinery:
— type-B1 standards on particular safety aspects (e.g. safety distances, surface temperature, noise);
— type-B2 standards on safeguards (e.g. two-hands controls, interlocking devices, pressure sensitive devices, guards).
Type-C standards (machinery safety standards) deal with detailed safety requirements for a particular machine or group of machines.
This document is a type-C standard as stated in ISO 12100.
