Abstract

The literature dealing with corrosion by thermal-insulating materials in residential buildings is reviewed. Current corrosiveness test methods are discussed. In view of their shortcomings, the need for a new procedure is evident. Possible methods applicable to various types of insulation are considered. The program for developing the new procedure is outlined. Preliminary test results indicate relationships between existing coupon and rapidly executable electrochemical tests. Field data, which are beginning to be collected, are needed to establish the validity of the new test and its ability to predict behavior under service conditions.
