Harmonization of rapid machine testing of fiber quality

Research output: Contribution to specialist publicationArticle


Harmonization means that high volume instruments (HVIs) measurements at diverse locations agree with one another within statistically known and acceptable probabilities. Some components that make up an adequate system of process and quality controls for an HVI cotton classification system includes machine error must be minimized by well engineered and constructed HVIs, cotton samples must be representative of an entire cotton bale, and equilibrium moisture content must be achieved in the cotton samples before testing. If cotton is being tested on a daily basis, then checktesting must be done on a daily basis and the lag between satellite testing and checktesting must be minimized, otherwise, errors cannot be corrected in a timely manner and the integrity of the data on fiber properties is lost. The relaxing of the harmonization requirements means that the accuracy of the data can be routinely challenged and adjudicated with the use of an established retesting procedure.
