Many accredited testing labs are required to participate at least twice a year in an international comparison test. Therefore we offer for the first time in 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. Determination of Chlorine content, Sulphur content and heavy metals are not offered on purpose, as these values usually are below the detection limit of the participating labs. A statistical evaluation is therefore not possible. For these test methods the participation within the ICT-FT is recommended.

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"
