Detailed Standards Coverage

EN 18097:2025 – Metrological Requirements and Test Methods for Non-Catching Type Rain Gauges

Hydrometry – Measurement of precipitation intensity – Metrological requirements and test methods for non-catching type rain gauges

EN 18097:2025 sets out rigorous laboratory procedures and equipment requirements for calibrating and confirming the accuracy of non-catching rainfall measuring instruments. Unlike traditional catchment gauges, these devices employ optical, impact, or radar technology to quantify precipitation without physically collecting water—critical for modern meteorological research, hydrology, and environmental monitoring.

The standard introduces a universal calibration protocol that focuses solely on the instrument’s measurement accuracy in controlled laboratory conditions, independent of the technology’s internal mechanisms or field performance. This ensures instruments can be classified based on objective, reproducible metrics. Users can reliably specify the right gauge class for weather observation, civil engineering, water resource management, and research.

Key requirements include:

• Use of traceable and characterized drop generators for calibration
• Testing with water drops across at least three (preferably five) diameters (0.5 mm to 6 mm)
• Raw measurement data (drop size, velocity) evaluation and statistical analysis across multiple instrument positions
• Specification of calibration uncertainty and statistical significance
• Exclusion of proprietary data filtering from core calibration results unless required for the instrument’s operation

Target industries include hydrology, meteorology, government environmental agencies, and manufacturers of precipitation monitors.

Practical implications:

• Clearer, standardized declarations of instrument accuracy
• Streamlined procurement and specification for infrastructure projects
• Easier comparison and compliance checks in international contracts

Notable changes: This standard is among the first to offer a consensus laboratory approach for modern non-catching instruments, built on Europe’s EMPIR 18NRM03 project results.

Key highlights:

• Repeatable laboratory classification independent of measurement technology
• Statistically robust calibration methodology using traceable reference drops
• Comprehensive minimum requirements for test setup, drop generation, and data handling

• Fabrication of 2D material FETs with well-defined channel and contact geometries
• Performing electrical measurements in a 4PP configuration to capture accurate transconductance, avoiding errors from contact resistance
• Data analysis protocols for extracting transfer curves and mobility values

Target users include nanotechnology labs, electronics manufacturers, research entities, and supply chain providers involved in 2D materials.

Implementation impact:

• Enables reproducibility and comparability in reporting device performance
• Facilitates fair benchmarking of commercial graphene products
• Supports qualification and certification in nano-electronics supply chains

Notable advances: The standard prioritizes four-probe over two-probe setups, responding to industry-identified pitfalls in current extraction methods.

Key highlights:

• Improved measurement repeatability and accuracy with the 4-probe FET method
• Applicable to a broad suite of 2D materials and devices
• Detailed requirements for measurement setup, sample preparation, and analysis

Industry Impact & Compliance

The December 2025 standards package provides both industry-wide and sector-specific benefits:

• Operational improvements: Measurable progress in laboratory calibration, process validation, and device certification—reducing variability and ambiguity
• Compliance certainty: Clear definition of acceptable methods and performance classes accelerates both internal QA approval and regulatory acceptance
• Product and data quality: Enables procurement of scientifically validated equipment, predictive maintenance, and audit-ready data integrity

Adoption timelines will depend on contractual requirements, local accreditation, and sectoral regulation. Early implementation supports competitive advantage, while non-compliance may lead to data rejection, operational inefficiency, or regulatory nonconformance.

Risks of non-compliance:

• Faulty measurements, leading to bad decisions or failed projects
• Poor reliability in nanodevice yields and electronic products
• Rejection of data submissions to health authorities or partners

Technical Insights

Several common technical themes emerge:

• Traceable calibration and robust data analysis underpin every new measurement standard, from rainfall gauges to nano-FETs
• Four-terminal, probe-based, or kinetic model approaches are increasingly mandated for eliminating known sources of error in physical and biochemical assays
• Transparency in calibration and data mapping: Open, declared methods and clear specification of limitations or excluded processes
• Best practices for implementation:
  • Validate and characterize reference instruments or samples
  • Employ statistical rigor with sufficient sample sizes and position randomness
  • Document all test parameters and environmental conditions
  • Harmonize data models or software mapping before integration into workflows

Testing and certification strategies: Manufacturers and labs should partner with recognized assessment bodies aligned with the relevant standard—using traceable methods, maintaining up-to-date documentation, and performing proficiency testing where available.
