The 2020-4 Round Trial under the auspices of the Task Force on Commercial Standardization of Instrument Testing of Cotton (CSITC Task Force) was conducted during the 4th quarter of 2020, and results were sent out on December 22nd.

Despite Corona lockdowns, 65 testing facilities from all continents submitted results for in sum 119 instruments.

With a median Overall Evaluation Result (OER) of 0.33 or exactly 0.32538, this evaluation is the second best result ever (just behind RT 2019-2 with 0.32). Even better: The last three Round Trials (2020-2 to 2020-4) are all on this extremely good level of 0.33, whereas else never results better than 0.35 have been achieved. So the average of 2020 is with 0.34 the best year ever. This confirms that the participating laboratories are improving continuously - which is the main aim of the Round Trials.

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 zane@icac.org). Participation cost is 275 USD per Round Trial (including up to 4 instruments), or 1100 USD for a complete year.
