Abstract

This article describes the construction and properties of a new type of guarded hot plate apparatus for the investigation of thermal insulations. The article begins with a general discussion of some of the characteristics of the conventional unit, noting especially the long time required to reach steady state conditions and the accuracy given in round-robin-tests. Errors when measuring in a onesided guarded hot plate are discussed and calculated. A description is given of the constructed guarded hot plate and its characteristics. It is shown that it is possible to reach steady state in very moderate periods of time combined with stable and accurate measurements.
