Overview
EN ISO 19014-3:2018 (ISO 19014-3:2018) specifies minimum 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 (as defined in ISO 6165). Published by CEN from the ISO technical work, this part of the ISO 19014 series focuses on how SRP/CS hardware should withstand real‑world environmental stresses to maintain functional safety.
Key topics and technical requirements
The standard defines required environmental tests and related purposes without prescribing design details. Main technical topics covered include:
- Functional status classifications (Class A–D) to categorize component safety roles.
- Environmental tests and requirements, each with stated purpose and test method, including:
- Dust exposure
- Chemical resistance
- Salt spray (corrosion resistance)
- Pressure wash
- Random vibration
- Operating shock
- Temperature cycles
- Thermal shock
- Humidity cycles
- Overvoltage and undervoltage (reset behaviour)
- Electromagnetic compatibility (EMC)
- Reverse polarity
- Annex A: an informative test checklist to help plan and document environmental qualification activities.
- Normative references and terms/definitions to ensure consistent interpretation.
Note: EN ISO 19014-3:2018 provides minimum test requirements and methods; specific test parameters, acceptance criteria and implementation are detailed in the standard text.
Practical applications
This standard is used to ensure that safety‑related electronic/electrical components on earth‑moving machinery remain reliable under environmental stressors commonly encountered on construction and mining sites. Typical applications:
- Environmental qualification of sensors, controllers, actuators and electronic control units (ECUs) used in SRP/CS.
- Component selection and validation during product development for excavators, loaders, graders and attachments.
- Test planning and acceptance checks in laboratory and production test facilities.
- Supporting risk assessments and functional safety documentation for machinery compliance.
Who should use this standard
- OEMs and system integrators of earth‑moving machinery
- Component and module manufacturers (electronic/electrical)
- Test laboratories and certification bodies performing environmental qualification
- Safety engineers, R&D teams and quality managers responsible for functional safety of SRP/CS
- Procurement teams specifying supplier test evidence
