Overview
ISO 25119-4:2018/Amd 1:2020 is an important amendment to the international standard covering safety-related parts of control systems in tractors and machinery used for agriculture and forestry. This document, published by ISO, focuses on the production, operation, modification, and supporting processes for these safety-critical control components. It ensures that manufacturers, operators, and service providers adhere to rigorous safety practices throughout the lifecycle of agricultural and forestry machinery.
The amendment updates normative references within the original ISO 25119-4:2018 to reflect the latest revisions and clarifications in related parts of the ISO 25119 series, strengthening the overall framework for functional safety in this sector.
Key Topics
- Safety-Related Control Systems: Emphasizes stringent safety requirements for parts critical to machine control to minimize risks during agricultural and forestry operations.
- Production Processes: Defines standards for manufacturing control system components, ensuring consistency and safety compliance from the initial fabrication stages.
- Operation and Modification: Provides guidelines for safely operating and modifying equipment, addressing changes that could impact the integrity and performance of control systems.
- Supporting Processes: Covers maintenance, testing, and verification procedures to sustain safety compliance throughout the equipment’s operational life.
- Normative References Update: Aligns references to related standards in the ISO 25119 series, including updates to ISO 25119-1, ISO 25119-2, and ISO 25119-3, to maintain coherence across the safety-related control system standards.
- International Collaboration: Developed by ISO Technical Committee ISO/TC 23/SC 19 with cooperation from the European Committee for Standardization (CEN/TC 144), reflecting global best practices.
