Harmonisation of HVI Strength Calibration

Ralf Baeumer and Thomas Schneider


ABSTRACT

The restriction of the International Calibration Cotton Standards means one step further towards harmonizing the measurement technology for fibers worldwide. Especially in Europe the users of HVI preferred the ICC-Standards to calibrate their equipment because of the reliability e.g. of the strength measurement based on the Stelometer-level. Others who used the HVI-Calibration Cottons came in conflict with users of ICC-Standards because of the different level focused on strength measurement. This situation led to some trouble and misunderstanding in the international trade of cotton, and problems also arose within the business between involved companies. Knowing this, some research was done at the Fibre Institute Bremen (Faserinstitut) to provide some scientific knowledge on the new situation focused on the calibration of HVI and the reliability of the results as well. The basis Stelometer is no longer available to check the HVI systems.
