Plan for a Round Robin of Hot Boxes

摘要

A plan for an interlaboratory round robin series of tests sponsored by the American Society for Testing and Materials (ASTM) using calibrated or guarded hot-box equipment is described. These testing methods are designed to measure the thermal conductance of full-scale building sections such as walls, roofs and floors. Results from about 25 hot boxes in the U.S. and Canada are expected to produce improved calibration techniques and repeatability and uncertainty information useful for improving ASTM specifications.
