Overview
ISO 19014-3:2018 - "Earth-moving machinery - Functional safety - Part 3" defines the environmental performance and test requirements for electronic and electrical components that are identified as safety-related parts of the control system (SRP/CS) on earth-moving machinery (EMM) and their attachments. It sets minimum environmental testing expectations so SRP/CS components reliably perform their safety functions across the harsh conditions typical for construction and earth-moving equipment.
Keywords: ISO 19014-3:2018, earth-moving machinery, functional safety, environmental testing, SRP/CS, electronic components, electrical components.
Key Topics
- Scope and classifications
- Applies to SRP/CS used on EMM as defined in ISO 6165.
- Defines functional status classifications (Class A–D) to guide test severity and applicability.
- Environmental and electrical test categories
- Contaminants: dust and chemical resistance tests.
- Corrosion/water: salt spray and pressure-wash requirements.
- Mechanical stress: random vibration and operating shock.
- Thermal stress: temperature cycles and thermal shock.
- Moisture: humidity cycles.
- Electrical stress: overvoltage, undervoltage (reset behavior), reverse polarity.
- Electromagnetic compatibility (EMC): required testing per machine EMC standards.
- Test governance
- References established norms such as ISO 6165, ISO 13766-1/2 (EMC), ISO 16750 (electrical/chemical loads), ISO 20653 (IP codes), and relevant IEC environmental test procedures (e.g., IEC 60068 series).
- Includes a test checklist (informative) to help structure validation.
Applications / Who Should Use This Standard
- Machine manufacturers (OEMs) - to specify, design and validate SRP/CS hardware for compliance and durability.
- Component suppliers - to ensure parts meet environmental and electrical robustness expected in EMM safety systems.
- Test laboratories - to develop test plans and reports that align with ISO 19014-3 requirements.
- Safety engineers and system integrators - to select components and verify that SRP/CS meet required functional safety performance under environmental stress.
- Regulators and conformity assessors - to evaluate whether SRP/CS achieve sufficient resilience for deployment in earth-moving equipment.
Related Standards
- ISO 19014 series (Parts 1–5) - broader functional safety framework for EMM.
- ISO 6165 - EMM types and terminology.
- ISO 13766-1 / 13766-2 - EMC requirements for earth-moving and building construction machinery.
- ISO 16750 series - road-vehicle environmental testing guidance.
- ISO 20653; IEC 60068 series - protective and environmental testing procedures.
Practical value: ISO 19014-3:2018 helps reduce safety failures caused by environmental and electrical stresses, supports robust SRP/CS design, and harmonizes test methods across suppliers, OEMs, and test labs in the earth-moving machinery sector.
