Test Procedure to Measure the Fuel Permeability of Materials by the Cup Weight Loss Method
This test standard covers the procedure for measuring the permeation of fuel or fuel surrogates through test samples of elastromeric, plastic, or composite materials, up to about 3 mm thick. The method involves filling a test cup with the test fluid (fuel or fuel surrogate), sealing test sample over the open end of the cup, and then placing the sealed container into an oven at the desired test temperature and measuring the weight loss over time. Permeation rates are calculated from the rate of weight loss and the exposed area of the test sample.
