Interlaboratory Studies (ILS): Setting New Milestone for Refractory Testing by FG Feuerfest
What are Interlaboratory Studies (ILS) and why do they matter for the refractory value chain? Interlaboratory Studies (ILS), also known as round-robin tests are anonymous proficiency tests for testing laboratories. They enable an objective assessment of the precision, accuracy, and reliability of testing methods by comparing the results from different laboratories. They are essential for quality assurance and accreditation. Moreover, ILS provide a structured framework for laboratories to collaboratively evaluate and refine testing methods. By analyzing results from multiple labs, inconsistencies or deviations in procedures can be identified and addressed. This process helps:
- Customer Trust: By demonstrating the accuracy and transparency of your test results, you can strengthen your customers’ trust in your products and services.
- Harmonize methods: Ensure all laboratories follow the same protocols, reducing variability in results.
- Validate methods: Confirm that a testing procedure is reliable, repeatable, and reproducible across different environments.
- Improve precision: Identify sources of error (e.g., equipment, operator technique) and refine methods to minimize them.
- Establish best practices: Create guidelines or standards (e.g., ISO, DIN, or industry-specific) that define how tests should be conducted to achieve consistent results.
Finally, ILS generate data that can be used to develop Certified Reference Materials (CRM). CRMs are consistent, stable materials with well-defined properties, certified by a technically valid procedure. They serve as:
- Calibration tools: Labs use CRMs to calibrate equipment and verify that their measurements are accurate.
- Quality controls: CRMs allow labs to monitor their performance over time and compare results with other labs.
- Benchmarking: They provide a common reference point for evaluating the accuracy of new methods or materials.
Until now, no interlaboratory studies on refractory products have been open to all actors of the refractory chain value, nor have any certified reference materials been established. FGF addresses this issue and aims to set new milestones for the refractory industry.
