ASTM F119-82(2015)

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

SIGNIFICANCE AND USE
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.
SCOPE
1.1 This test method provides standard conditions for determining the rate of grease penetration of flexible barrier materials. Pinholes, which can be measured by a separate test, will increase the rate of grease penetration as determined by this test method.  
1.2 The values stated in SI units are to be regarded as standard. The values given in parentheses are for information only.  
1.3 This standard does not purport to address the safety concerns associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

3. Summary of Test Method
3.1 Flexible barrier materials, uncreased or creased by a standard procedure, are exposed on one side to grease contained in a
weighted cotton patch. The time required to show a visual change caused by wetting (reduction in light scattering) of a
ground-glass back-up plate is measured.
4. Significance and Use
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.

NOTE 1—The ground-glass backing plates may be prepared from 2 by 2-in. squares of ⁄8-in. plate glass by lightly grinding the surface with a silicon
carbide abrasive as follows: Place a piece of plate glass approximately 1ft square on a flat surface. Mix some abrasive and water in small quantities to
make a fairly uniform paste. Place one of the 2-in. squares of plate glass face down in the abrasive paste, and rotate it in a figure eight movement with
the finger tips using the slightest amount of pressure. When the paste gets too heavy, remove the plate glass square from the bed and wash it to remove
