CSITC ROUND TRIAL 2025-4 COMPLETED in December 2025.
If you are not part of the CSITC Round Trials now, please register for 2026.
The 2025-4 Round Trial under the auspices of the ICAC Task Force on Commercial Standardization of Instrument Testing of Cotton (CSITC Task Force) was conducted jointly by the Fibre Institute Bremen (FIBRE) and USDA AMS during the 4th quarter of 2025, and results were sent out on December 23rd.
70 testing facilities from all continents submitted results for in sum 176 instruments. Jointly with RT 2025-3, these are the highest numbers of instruments since the start of the Round Trials in 2007. Laboratories are more and more using the chance to check each high volume instrument in their laboratory and prove their accuracy and precision.
For each instrument, an overall evaluation result (OER) is calculated, which shows the overall deviations from the reference values for all samples and all properties. Laboratories are getting a detailed analysis report for each instrument. In addition, laboratories are getting an enhanced certificate stating the status of their instruments in comparison to all participating labs/instruments with a statement as to whether the laboratory's instruments are in the top 10%, top 25%, top 50% or top 75%.
The median Overall Evaluation Result (OER) of all participating instruments in this latest Round Trial is 0.341, which is in the usual range since RT 2018.
In sum, 88 different laboratories from 30 countries participated in 2025. 240 different instruments were evaluated with in sum 573 instrument evaluations
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, but a detailed analysis of their results and deviations from the reference values, which helps the laboratories to improve.
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 Ms Maria Borisova - maria@icac.org). Participation cost for 2026 is 400 USD per Round Trial (including up to 4 instruments), or 1600 USD for a complete year. Registration is open all year, but the earlier you register, the earlier you can compare your results to more than 100 instruments worldwide.
Join the CSITC Round Trials if you want to be part of this success story!
