BS EN ISO 19014-1:2018

This document provides a methodology for the determination of performance levels required for earth moving machinery (EMM) as defined in ISO6165.

A Machine Control System Safety Analysis (MCSSA) determines the amount of risk reduction of hazards associated with control systems, required for Safety Control Systems (SCS). This reduction is quantified by the Machine Performance Level (MPL), the hazards are identified using the risk assessment principles as defined in ISO12100 or by other means.

NOTE1 Step2 as shown in AnnexA demonstrates the relationship between ISO12100 and ISO19014 as a complementary protective measure.

NOTE2 ISO19014 can also be used to assess the functional safety requirements of other off-road mobile machinery.

For those controls determined to be safety-related, the characteristics for architecture, hardware, software environmental requirements and performance are covered by other parts in ISO19014.

ISO19014 covers the hazards caused by the failure of a safety control system and excludes hazards arising from the equipment itself (for example, electric shock, fire, etc.).

Other controls that are not safety control systems (SCS), that do not mitigate a hazard or perform a control function and where the operator would be aware of a failure, are excluded from this standard (e.g. windscreen wipers, head lights, cab light, etc.).

NOTE3 A list of safety control systems is included in AnnexD.

NOTE4 Audible warnings are excluded from the requirements of diagnostic coverage.
