ISO 19014-3:2018 PDF

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.
