Precision measurements on fibrous glass insulation
Abstract
A technique for measuring the thickness of low density fibrous glass materials is investigated. The method of measurement described provides a higher degree of accuracy than previously accomplished. The procedure determined a specific force to be used for measuring. Also, a stacking technique was carried out to see what effect placing a number of test samples on top of each other would have. The results of the entire testing will aid in the development of a standard reference material be used for thermal resistance measurement systems.
