ISO Standards announced for safety-related parts of control systems.
Press Release Summary:
ASABE announces 4 international standards that provide guidelines for design and assessment of safety-related electrical and electronic systems on tractors used in agriculture and forestry. ISO 25119 series adopts risk-based design approach while providing means of specifying performance levels for safety-related functions. Intended to reduce specific risks under all operating conditions, standards provide requirements for entire lifecycle of control system, from design through decommissioning.

New Standards Announced for Safety-Related Parts of Control Systems
ST JOSEPH, MICHIGAN - The American Society of Agricultural and Biological Engineers (ASABE) announces the publication of four new international standards that provide guidelines for the design and assessment of safety-related electrical and electronic systems on tractors used in agriculture and forestry.
These four new standards, parts 1 to 4 of "Tractors and machinery for agriculture and forestry -- Safety-related parts of control systems," were recently published in English and French for international use. They are titled as follows:
ISO 25119-1 Part 1: General principles for design and development
ISO 25119-2 Part 2: Concept phase
ISO 25119-3 Part 3: Series development, hardware and software
ISO 25119-4 Part 4: Production, operation, modification and supporting processes
The ISO 25119 series adopts a risk-based design approach while providing a means of specifying performance levels for safety-related functions. Intended to reduce specific risks under all operating conditions, the standards provide requirements for the entire lifecycle of the control system, from design through decommissioning. The safety-related components can consist of hardware or software, can be separate or integrated parts of a control system, and can either perform solely critical functions or form part of an operational function. As specified in the new standards, the design and validation of the safety components are combined as part of a risk assessment. Performance levels and categories defined in the standard can be applied to the control systems of both simple and complex mobile machines as well as to those of protective equipment, such as interlocking or pressure-sensitive devices.
ASABE is the accredited administrator for the US technical advisory group to the ISO committee on Tractors and Machinery for Agriculture and Forestry (TC23), and seven of its subcommittees. Committee membership is open and typically comprises individuals with an academic or commercial interest in the subject matter. Participation in standards development benefits commerce as well as the public by ensuring issues such as consumer safety and evolving technology are addressed in a thorough and timely manner and by reducing trade barriers that can occur in the absence of standardization.
