Abstract
The quality of heat insulation materials is tested and/or compared in a portable structure in which two heat insulation materials are subjected simultaneously to heat flow from a single common metal-clad heating element and the quantity of heat flow through said material is measured and compared. In one case the portable structure has two conveniently accessible cavities within which equal amounts of such insulation, in flat form, may be placed in contact with corresponding opposite sides of a single common metal-clad planar heat source. In a modification of the invention two tubular insulating materials each of the form and type for insulating pipe, is placed around a metal-clad round heating element and the amount of heat flowing from the heating element and through a corresponding one of said materials is measured and compared using individual thermopiles secured to the outer surface of each material.
