Overview

EN ISO 19014-1:2018 (Corrected version 2019-02) defines a methodology for assessing functional safety of control systems in earth-moving machinery (EMM). It specifies how to perform a Machine Control System Safety Analysis (MCSSA) to determine the Machine Performance Level (MPL) required to achieve adequate risk reduction for safety-related parts of the control system (SRP/CS). The standard complements ISO 12100 risk assessment principles and applies primarily to EMM (per ISO 6165) but can also be used for other off‑road mobile machinery.

Key Topics

• Machine Control System Safety Analysis (MCSSA): Method to identify hazards related to control-system failures and to quantify required risk reduction.
• Machine Performance Level (MPL): A discrete metric used to specify the level of risk reduction required for safety control systems (SCS).
• Risk assessment integration: Uses ISO 12100 principles (see Annex A process flow) to classify hazards, exposure, and the possibility to avoid harm.
• Scope and exclusions: Covers hazards caused by SCS failure; excludes hazards arising from the equipment itself (e.g., electric shock, fire). Non‑safety controls that do not mitigate hazards and whose failures would be evident to the operator (e.g., wipers, lights) are excluded. Audible warnings are excluded from diagnostic coverage.
• Supporting material: Informative annexes include a process flow chart (Annex A), table of warning/operation indicators (Annex B), an MCSSA example (Annex C) and a list of possible SCS on earth‑moving machines (Annex D).
• Relationship to other ISO 19014 parts: Performance characteristics for architecture, hardware, software, environmental requirements and verification are addressed in other parts of the ISO 19014 series.

Applications

• Machine manufacturers: Use EN ISO 19014-1 to define safety requirements during design and to allocate MPLs to safety-related controls.
• Safety engineers and system integrators: Apply MCSSA to evaluate control system designs and to identify necessary diagnostic and redundancy measures.
• Regulators and health & safety bodies: Reference the standard when assessing compliance and risk reduction measures for earth‑moving machinery.
• Maintenance and service providers: Use MPL outcomes to plan validation, verification and periodic checks of safety control systems.

Related Standards

• ISO 6165 - Defines earth‑moving machinery types and terms (scope linkage).
• ISO 12100 - General machinery risk assessment and risk reduction principles (used within MCSSA).
• Other parts of the ISO 19014 series (design, software, transmission, and performance tables) provide detailed requirements for architecture, hardware and software referenced by Part 1.
