Overview - ISO 13374-2:2007 (Data processing)
ISO 13374-2:2007 is the part of the ISO 13374 suite that specifies the information model and processing model requirements for open condition monitoring and diagnostics (CM&D) systems. It defines how CM&D software architectures should structure, process and represent machine condition data to enable interoperability, data exchange and plug‑and‑play integration across vendors and platforms.
Key topics and technical requirements
- Reference information model: A non‑proprietary conceptual schema that defines primary data objects, attributes, types and relationships (UML recommended).
- Semantic definitions: Standardized, human- and machine-readable definitions (e.g., natural language and optional ontologies like RDF) for major data objects.
- Implementation data model: Concrete schema formats for storage/transfer (XML/XSD recommended, relational schemas or file-description schemas accepted) that conform to the conceptual model.
- Reference data library: Centralized code tables and taxonomies (asset types, measurement locations, unit codes, failure/root cause codes) with support for industry- and customer-specific entries and multilingual reference codes.
- Data document definition: Standard formats for publishing/importing/exporting datasets and reference libraries (ASCII/binary record descriptions or XML documents).
- Data types and formats: Support for single-value time series, FFT spectra, CPB spectra, time waveforms, sample test data, thermographic images and binary large objects (BLOBs).
- Timestamping: Use of ISO 8601 lexical format referenced to UTC with local timezone offset.
- Processing architecture (blocks): Functional decomposition into blocks such as Data Acquisition (DA), Data Manipulation (DM), State Detection (SD), Health Assessment (HA), Prognostic Assessment (PA), and Advisory Generation (AG), plus block configuration, archiving, external interfaces and presentation considerations.
- Standards alignment: References to XML, UML and middleware technologies and to standards such as ISO 13374‑1 and ISO/IEC 14750.
Applications and who uses it
- Software architects and developers building CM&D platforms who need a standardized information and processing blueprint.
- System integrators and OEMs aiming for interoperable condition monitoring systems and vendor-neutral data exchange.
- Reliability engineers, maintenance managers and asset owners who want consistent diagnostics, trending and prognostics across tools.
- Tool vendors and service providers implementing data import/export, archival and presentation layers that conform to industry schemas.
Benefits
- Enables interoperability and reduced integration costs.
- Promotes consistent data semantics, traceability and exchangeability.
- Supports standardized diagnostics, health and prognostic workflows for better asset management.
