The 2020-3 Round Trial under the auspices of the Task Force on Commercial Standardization of Instrument Testing of Cotton (CSITC Task Force) was conducted during the 3rd quarter of 2020, and results were sent out on September 29th.

Despite Corona lockdowns, 59 testing facilities from all continents submitted results for in sum 121 instruments.

With a median Overall Evaluation Result (OER) of 0.33, the result is confirming the very good level between 0.32 and 0.39 during recent Round Trials, which means a substantial reduction of interlaboratory result variation of in average more than 30% compared to the years from 2007 to 2015. Especially the results for Micronaire are on an extremely good level this time - the best ever seen since the start of the Round Trials in 2007.

Round Trials serve to improve cotton instrument testing worldwide by providing detailed, confidential, diagnostic results to each participating laboratory. Participating labs do not receive pass/fail results.

Information about CSITC and a general summary of Round Trial results (information for individual laboratories is confidential) are available on this web site csitc.org --> CSITC Round Trials --> Round Trial Results. Any other general information can be found on icac.org

The organizers of the Round Trial (ICAC, Faserinstitut Bremen and USDA-AMS) are continuing their work on the Round Trials and laboratory participation. Every testing facility can join this activity at any quarter of the year. For this, please contact the ICAC secretariat for your participation (csitcsecretariat@icac.org or yana@icac.org). Participation cost is 275 USD per Round Trial (including up to 4 instruments), or 1100 USD for a complete year.
