Increased vehicle intelligence requires specific safety assessment also for vehicles in the agricultural and forestry industry

Frequently they are equipped with intelligent electronics – and this is also true for machinery in the agricultural and forestry industry like driverless tractors with combined harvester or automated felling and extraction equipment. Therefore, manufacturers need to ensure compliance to ISO 25119 standard for their applications. Safety goals need to be fulfilled, conforming to specified Agricultural Performance Levels (AgPL).

To ensure vehicle safety manufacturers must not only have a look at certain development phases. Instead, there is a need to inspect the whole system within the entire vehicle or machinery life cycle. This stretches from the first developmental steps to decommissioning.

What is defined in the safety standard ISO 25119 for agricultural and forestry machinery?

ISO 25119 defines general principles for the design and development of safety-related parts of EUC control systems (SRP/CS) on tractors, municipal equipment like street-sweeping machines and other machines used in agriculture and forestry. The standard specifies the characteristics and categories required of SRP/CS for carrying out their safety-related functions and refers to any possible hazard which could be caused by any interference behavior related to the safety-related parts of electrical/electronic/programmable electronic systems (E/E/PES).

The standard ISO 25119 for tractors and machinery for agriculture and forestry is an industry-specific implementation of IEC 61508 and resembles a merger of modified and simplified ISO 26262 (automotive functional safety) and ISO 13849 (machinery functional safety). It defines the Agricultural Performance Levels (AgPL) and consists of four main parts:

  1. Part one defines the management aspects of a functional safety project and relates to the general principles for design and development
  2. Part two deals with the necessary safety concept and the requirements for risk analysis.
  3. Part three deals with hardware and software development and the associated tests.
  4. Part four of ISO 25119 deals with the functional safety aspects of production, operation, modification and supporting processes.

Why is a functional safety assessment to ensure tractor safety and safety of machinery for agriculture and forestry important?

For vehicle safety, various standards are in place. By demonstrating compliance to the relevant functional safety standards, the safety of your vehicles can be ensured.

The assessment according to ISO 25119 considers all relevant requirements for your agricultural and forestry vehicles. It ensures, that neither the environment nor the user will be harmed due to incorrect functionality of the vehicle.

Using ISO 25119 to evaluate the overall safety of your tractors and other agricultural and forestry vehicles and/or corresponding systems provides multiple benefits for your business and customers:

  • Ensure compliance with ISO 25119 and minimise the risk of harm to people
  • Maintain your competitive advantage by ensuring market access to global markets due to relevant international regulations compliance
  • Avoid costly product recalls and reputational damage due to safety hazards
  • Strengthen your customers’ trust in your agriculture and forestry machinery by ensuring high product quality and safe performance
