Project management and neutral evaluation by Dr. Georg Szczendzina
The project manager for our round robin tests of solid fuels analytics and sampling of solid fuels is qualified chemist Dr. Georg Szczendzina, of the Chamber of Commerce and Industry Northern Westphalia publicly appointed and sworn commercial chemist, expert and sampler for solid fuels.
Proficiency testing: improving precision and accuracy
Why DCC proficiency testing interlaboratory tests?
The evaluation of measurement results is always based on a proper and professional sampling. It is the foundation of the analysis not only of solid fuels. And what would be a house without a foundation? Who can exercise the utmost precision in sampling prevents incorrect results and saves possible costs for remedy or recourse.
The objectives of the DCC-round robin tests are
- Checking the accuracy of sampling and
- the determination of fuel parameters
serve the needs are for quality assessment and billing, or assess the technological properties.
Incorrect results can be detected only by interlaboratory tests. Here, some basic errors can be prevented.
Prevent systematic variations in the analysis
With the proposed round robin tests, we allow participants to detect systematic deviations which are due to apparatus or method cause. The validation of test methods (standard or in-house method) have priority.
Quality assurance for laboratories
The aim of our round robin tests is to ensure the quality of test results and calibration results. The round robin tests are aimed at both accredited and not accredited laboratories. By the external quality assurance measure we want to give the opportunity to document their quality to the accredited laboratories. The measurement uncertainty in accordance with DIN EN ISO/IEC 17025 can be estimated on the basis of participation. Even for non-accredited laboratories round robin tests are a valuable tool for quality assurance.
