The accurate and reliable measurement of the chemical composition of mineral wool is the corner stone in EUCEB´s evaluation to check if produced mineral wool is within the chemical range of the exonerated reference fibre. It plays a key role in the trust that Third Parties have in the EUCEB certification scheme.
In order to improve continuously and to reinforce confidence in the safety of mineral wools, EUCEB performed another comparative testing campaign with all external labs and many internal labs used by its certificate holders. This “Round Robin Test” was managed independently by BCCA, the Belgian Construction Certification Association.
One sample of glass wool and one sample of stone wool were sent to all laboratories without any information on their chemical composition. The laboratories analysed the samples and sent the results to BCCA. BCCA shared them anonymously with an independent expert within statistical analysis who did the statistical evaluation.
All external laboratories performed well but one. It was requested to take corrective actions and has been removed from the list of approved laboratories for the time being. So, all approved laboratories are fully in line with EUCEB expectations.
EUCEB and BCCA will continue their efforts to constantly improve the robustness of the EUCEB certification scheme and to keep the customers´ confidence in the safety of mineral wools at its high level.
