Many accredited testing labs are required to participate at least twice a year in an international comparison test. Therefore we offer since 2016 besides the comparison tests in the field of fuel testing for solid biofuels and solid SRF (ICT-FT) a laboratory comparison test exclusively for wood pellets. This laboratory comparison test is also especially suitable for ENplus® approved and listed testing labs.

The statistical evaluation of this comparison tests is carried out in accordance to ISO/IEC 17043 (mean value, standard deviation, outlier according to Grubbs, outlier according to Cochran, z-score) as well as repeatability and reproducibility.

The ICT-PT laboratory comparison test is also listed in the international database for proficiency tests "eptis" http://www.eptis.bam.de.
