Research Project: Independent Round Trial of Uster High Volume Instrument Elongation Calibration

Location: Cotton Structure and Quality Research

Project Number: 6054-44000-079-13-R
Project Type: Reimbursable Cooperative Agreement

Start Date: Jan 1, 2017
End Date: Dec 31, 2017

The objective of this program is to conduct an independent round trial of High Volume Instrument (HVI) testing for cotton fiber elongation utilizing calibration routines developed by Texas Tech University including a minimum of 5 locations around the world and utilizing a diverse set of cottons which represent a wide range of elongation values. If the Texas Tech University calibration routine is unsuccessful, we will explore the alternative elongation calibration routine developed by CSIRO Manufacturing (Waurn Ponds, Australia).

A round trial will be conducted which includes a number of High Volume Instrument (HVI) instruments at a minimum of five locations around the world. The resources of the USDA will be used to obtain at least six samples, in sufficient quantity for the round trials, which represent a broad range of elongation of cotton fiber. Participating HVI units will be calibrated using the materials and methodology developed at Texas Tech University. Results will be analyzed and the efficacy of the elongation calibration will be determined. If time and material allows, the CSIRO elongation calibration routine will be examined using the same round trial samples by at least a sub-set of the laboratories involved in the primary round trial, based on availability.
