ASTM D722-93(1997)

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 problems, 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.
