About ISO 25119 (Agricultural Machinery Functional Safety)

This event covers the compliance, engineering, and verification requirements defined by ISO 25119.

ISO 25119 series covers safety-related control systems on agricultural and forestry tractors and machinery: AgPL performance levels, design, and validation for functions like hitch control, PTO engagement and steering assistance.

What it regulates

AgPL determination (a-e), hardware/software design requirements, and V&V for ag electronics operating with exposed persons and variable environments.

Who must comply

Tractor/implement OEMs and ag electronics suppliers; referenced for EU type approval of tractor control systems.

Key requirements of ISO 25119

  • Risk assessment to AgPL
  • Design requirements (25119-2/-3) with ag environmental profiles
  • Software lifecycle scaled to AgPL
  • Validation (25119-4)

Key concepts: ISO 25119

ISOBUS context
Distributed tractor-implement control (ISO 11783) whose safety functions cross vehicle boundaries.
AgPL
The agricultural performance level analog to PL/ASIL.
Bystander/child exposure
Ag risk models include unpredictable persons around machinery in fields and yards.

Frequently asked questions: ISO 25119

Tractor + implement: whose AgPL is it?

The safety function often spans both via ISOBUS; responsibility splits along the functional interface with documented assumptions — integration engineering mirrors machinery's integrator duties.
