ISO 19014-5:2026 - Tables of Performance Levels for Earth-Moving Machinery

Earth-moving machinery — Functional safety — Part 5: Tables of performance levels

This ISO standard provides both the methodology and the required performance levels (MPLr) for a detailed array of functions across different types of earth-moving machines. These performance levels can be directly mapped or applied to safety control systems (SCS) for functions like braking, steering, speed control, and operator presence within the entire portfolio of covered equipment—in line with ISO 6165:2022 definitions.

Scope & Requirements:

• Establishes normative tables (Annexes A–AA) that define the minimal acceptable machine performance levels for functions and scenarios across a wide range of machinery including dump trucks, loaders, excavators, graders, rollers, compactors, and specialized attachments.
• MPLrs derive from a Machine Control System Safety Analysis (MCSSA) process—calculating worst-case risk and applying it across the equipment’s functional safety requirements. Criteria consider hazards during operation, maintenance, and interaction with bystanders or co-workers.
• Requires SCS designers and machine manufacturers to cross-reference their implementations against these tables to confirm compliance with the identified MPLr for every safety function.
• Reiterates the necessity of maintaining up-to-date risk assessments (per ISO 12100:2010 and ISO 19014-1:2026), especially in the case of unique machine configurations, alternative applications, or new technologies (electric or hydrostatic systems, for example).
• Mandates that machines conform to ISO 19014-1, -2, and -4 for both risk quantification and effective risk reduction measures, ensuring a holistic, multi-standard approach to functional safety.

Use & Target Stakeholders:

• Essential for engineers involved in machine safety analysis, performance verification, and compliance documentation.
• A primary reference for procurement professionals assessing supplier adherence, as well as auditors and inspectors verifying fielded machinery against global best practices.

Practical Implications:

• Using the MPLr tables streamlines risk assessment by providing off-the-shelf baseline requirements for standard use-cases and machine types, avoiding redundant individual analyses where standardized data suffice.
• Integration of these tables into engineering design and technical documentation ensures alignment with international expectations and supports swift regulatory approvals.
• Keeps organizations audit-ready and well-positioned for cross-border equipment sales where adherence to ISO standards is a purchasing condition.

Key highlights:

• Contains detailed, function-by-function MPLr data per earth-moving machine type (over 20 equipment classes covered via exhaustive annexes).
• Enables traceability and mapping from risk scenarios to required safety system design.
