Standard Test Method for Grease Resistance of Paper
This test method gives a relative indication of the degree to which paper and products made from paper resist penetration by oils and grease commonly found in foodstuffs. The measured penetration times are greatly accelerated under the conditions of the test, in comparison to the time that might be required for grease penetration in an actual end-use application of the tested material.
While this test method may be used as a preliminary tool to select and predict paper or paper products for an intended end use, it is not a substitute for actual use tests with the material or product of interest.
This test method may also be useful in specifications where experience has shown that paper having a particular grease resistance as measured by this test method is suitable for an intended end use.
1.1 This test method covers paper and paper products that have been treated or designed to resist penetration by oils or greases commonly found in foodstuffs. Such papers include but are not limited to greaseproof, glassine, and vegetable parchment papers.
1.2 This test method provides relative data regarding the degree of grease resistance for the materials tested based on time required for penetration of a test specimen by turpentine under specified laboratory conditions. For paper or paper products that are not penetrated under these conditions by the upper arbitrary time limit of the test (1800 s), no relative information is provided.
1.3 The values stated in SI units are to be regarded as the standard. The inch-pound units given in parentheses are for information only.
1.4 This standard does not purport to address all of the safety concerns, if any, 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.
