Performance Criteria for Restoration Coatings for Porcelain Enamel Surfaces

摘要

In June 1982, the results of a laboratory-based study to develop interim performance criteria for restoration coatings for porcelain enamel surfaces were reported in NBSIR 82-2553, 'Development of Interim Performance Criteria for Restoration Coatings for Porcelain Enamel Surfaces'. Additional studies, consisting of a one-year field test of three of the five restoration coatings studied in the laboratory, were performed to assess the effectiveness of the interim performance criteria. The field test included periodic evaluation of the three restoration coatings applied to a total of nine bathtubs in public housing units in Alexandria, Virginia. The results of the field test were compared to the previous laboratory results and showed that the interim performance criteria were effective in selecting durable restoration coatings. This report presents the findings of the field test and includes the final performance criteria.
