Abstract
The paper gives the results of a series of co-operative laboratory aging tests made on Manila paper in oil sealed in glass tubes. The aging temperatures were 100, 120, and 135 degrees centigrade. The changes in tensile strength, elongation, folding tests, oil color, and oil acidity are given in tabular form in Tables I, II, and III. The tensile strengths of the paper in per cent of initial versus time are plotted in Figures 1, 2, and 3. The 120- and 135-degree-centigrade tests are completed. The 100-degree tests are being continued.
