Overview - ISO 22172-1:2020 (RMI for agricultural vehicles, web UIs)
ISO 22172-1:2020 defines user interface requirements for web-based repair and maintenance information (RMI) systems for vehicles used in agriculture and forestry. The standard gives manufacturers guidance on designing standardized, use-case driven RMI access: general principles, functional use-case definitions and technical requirement clusters. Annex A provides conformance procedures to verify that an RMI system meets the document’s requirements. Note: this part does not cover hardware, software or communication protocol requirements for on-board diagnostics (OBD) access.
Key topics and technical requirements
The standard focuses on practical, web-based RMI user experience and system behaviour. Major topics include:
- General information & basic principles - design principles for access control, information organization and usability.
- Use case definitions (functional requirements) - detailed UCs for common RMI interactions such as:
- User authentication, authorization and administration (registration, login, role/status management)
- Payment for RMI access
- Vehicle identification (VIN, model/serial number, product features)
- Selection and navigation methods (information type selection, product structure navigation, document ID)
- Retrieval of information packages (workshop procedures, wiring/hydraulic diagrams, service bulletins, recalls, maintenance schedules, spare parts, labour times, special tools)
- Electronic maintenance history and virtual stamping
- Contact requests, training/course information and vehicle diagnostics (DTC and symptom resolution)
- Technical requirements clusters - organized requirements for:
- Access-related data administration (IO data, access events)
- Technical infrastructure (presentation formats, internet connectivity expectations)
- Operations (system availability, user support, client PC operation)
- Conformance procedures (Annex A) - recommended checks to ensure compliance with stated requirements.
Practical applications and users
ISO 22172-1 is targeted at stakeholders involved in delivering, using or integrating web-based RMI systems:
- Vehicle manufacturers (VMs) - guidance for building compliant RMI portals and APIs
- Authorized repairers and dealers - predictable access to official repair information and maintenance schedules
- Independent operators (IOs) and service workshops - standardized workflows for locating procedures, parts and diagnostic guidance
- Software developers and system integrators - user interface and functional requirements for RMI applications, portals and service platforms
- Fleet managers and training providers - using standardized electronic maintenance history and training content
Benefits include improved safety, consistent maintenance procedures, easier parts identification and streamlined access control for web-based RMI.
