| Abstract | An apparatus to measure the thermal resistance of expanded polystyrene (EPS) has been developed at IRC as one of two elements of inexpensive instrumentation proposed for the quality assurance programs of the EPS industry. The other is a flexural strength apparatus and has been reported in other document. The apparatus reported here was used for testing 16 pairs of specimens selected from a set of EPS experimental products and the results were compared with those obtained on a Guarded Hot Plate (GHP) apparatus.The difference in each of these comparative tests varied from 0 to the maximum of 0.6 percent, while the mean difference was 0.03%. Yet th enew equipment is approximately ten times less expensive than a GHP apparatus and much easier to operate. It is therefore expected that this new equipment will be used by Canadian manufacturers of EPS (and other thermal insulating boards) as a tool for control of the production quality. |
