Overview - IEC TR 62130:2012 (Climatic field data including validation)
IEC TR 62130:2012 is a technical report published by the International Electrotechnical Commission (IEC) that provides traceable recommendations based on validated field data to inform updates to IEC 60721-2-1 (environmental conditions appearing in nature - temperature and humidity). The report documents a structured process for collecting, validating and comparing climatic field data and presents recommendations for revising climatic classification maps, types and parameter values used for product and environmental classification.
Key topics and technical content
- Purpose and scope
- Provides recommendations for updating the temperature and humidity classifications in IEC 60721-2-1 using validated field measurements.
- Data collection and validation (Task 1)
- Collation of field datasets from independent sources, organization in spreadsheets and validation (Annexes A and B present graphical and tabulated data).
- Traceability and comparison process (Task 2)
- A defined multi‑phase process to ensure traceability of temperature and humidity parameters, including identification of standards, data sources, comparison methods and decision criteria.
- Spatial analysis and impact assessment (Task 3)
- Procedures for analysing climatic maps and assessing the impact of proposed changes on existing classifications and product tests.
- Recommendations for updates (Task 4)
- Proposals covering naming of new climatic types, definitions, numerical values for parameters (mean annual extremes, annual extremes, absolute extremes) and updates to climatic class maps.
- Supporting figures and tables
- Includes maps of climatic types and groups, tables of climate-type thresholds (daily mean extremes, annual extremes, absolute extremes), and cross-reference tables.
Practical applications and benefits
- Standards revision - Provides evidence-based input for revising IEC 60721-2-1 climatic classifications.
- Product design and qualification - Helps designers and test labs select appropriate environmental classes (temperature and humidity) for reliability and environmental testing.
- Environmental testing and certification - Supports conformity assessment bodies and test houses in aligning test conditions with real-world climatic data.
- Reliability engineering and field deployment - Assists asset managers and field engineers to assess environmental exposure and lifetime predictions for equipment.
- Climate mapping and regulatory use - Useful for agencies updating climatic maps used in infrastructure and safety regulations.
Who should use this report
- Standards developers and technical committees (IEC TC 104)
- Environmental test laboratories and certification bodies
- Product designers, reliability and test engineers
- Climate data analysts and GIS specialists involved in climatic classification
