The Hose Measurement Task Force conducted a round-robin study to determine the measuring capability of automotive suppliers and users to simultaneously measure the Inside Diameter (ID)@ Outside Diameter (OD)@ Wall Thickness (Wall)@ and Wall thickness Variation (WV) of hose using a laser-based@ noncontact LOTIS QC-20 gauging device. Three (3) companies (all end users) participated in this testing with one of the three companies performing the GRR calculations presented herein. Based upon the round-robin study this report will detail procedures@ test measuring devices@ results@ and conclusions.
