Standard Test Method for Rate of Grease Penetration of Flexible Barrier Materials (Rapid Method)

Importancia y uso:

4.1 This test method is valuable in the development and selection of flexible barrier materials suited for use as grease barriers.

4.2 The test is rapid in comparison with other methods because of the extremely small quantity of oil required for detection (about 6 μg). The actual time to failure is a multiple of the values obtained by this test method. When permeation is through an absorbent structure such as kraft paper coated with polyethylene, the failure times will be longer and variable, depending on the variation in porosity and thickness of the structure.
