The internationally trusted set of standards for tractors and other agricultural equipment has been updated to promote safety and ensure control systems work as intended.
The ISO 25119, Tractors and machinery for agriculture and forestry – Safety-related parts of control systems, series of standards is widely used by the agricultural industry and its suppliers.
The standard sets out the general principles for the design and development of safety-related parts of control systems on tractors and self-propelled ride-on machines used in agriculture and forestry. It can also be applied to mobile equipment used in municipalities such as street-sweeping machines.
ISO 25119 also helps designers and manufacturers ensure that safety-related parts perform as intended, and covers system structure, fault detection mechanisms, reliability of components, operating stress, and environmental conditions.
The revised version of the International Standard includes a number of improvements based on feedback from end users.
Dipl.-Ing Hans Jürgen Nissen, Chair of the ISO technical subcommittee that developed and revised the series, said, “The key objectives of the revision were to harmonize ISO 25119 with, and ultimately replace, a European standard, under the Vienna Agreement, thus improving its relevance in the EU regulatory area.
“What’s more, changes were made to incorporate suggestions from end users, certification bodies, and experts involved in standardization to make it more user-friendly, understandable and useful,” Nissen added.
Standards in the ISO 25119 series are:
- ISO 25119-1, Tractors and machinery for agriculture and forestry – Safety-related parts of control systems – Part 1: General principles for design and development
- ISO 25119-2, Tractors and machinery for agriculture and forestry – Safety-related parts of control systems – Part 2: Concept phase
- ISO 25119-3, Tractors and machinery for agriculture and forestry – Safety-related parts of control systems – Part 3: Series development, hardware and software
- ISO 25119-4, Tractors and machinery for agriculture and forestry – Safety-related parts of control systems – Part 4: Production, operation, modification and supporting processes
The ISO 25119 series was developed by ISO technical committee ISO/TC 23, Tractors and machinery for agriculture and forestry, subcommittee SC 19, Agricultural electronics.
