Determination of the Water Vapor Resistance and Thermal Resistance of SampleMaterials Using a Sweating Hot Plate

摘要

A round-robin determination of certain textile properties has been proposed aspart of a TTCP PTP3 effort to facilitate the exchange of data between countries using different apparatuses. The objective of the study, Operating Assignment 9, is to see if the measured values of thermal and water vapour resistance of various fabrics are comparable between the SEA Sweating Hot Plate (used by Australia and Canada) and the Hohenstein Sweating Hot Plate (used by the United Kingdom and the United States). Several fabric samples were submitted for testing by each nation taking part in the round-robin tests. All nations tested the samples independently using their own equipment and test methods. The work presented is a detailed description of the test method used by Canada and the results achieved.
