1.1本试验方法为确定柔性屏障材料的油脂渗透速率提供了标准条件。针孔可以通过单独的测试进行测量，这将增加通过该测试方法确定的润滑脂渗透速率。 1.2 本标准无意解决与其使用相关的安全问题。本标准的用户有责任在使用前制定适当的安全和健康实践，并确定监管限制的适用性 . ====意义和用途====== 该试验方法对开发和选择适合用作油脂屏障的柔性屏障材料很有价值。 与其他方法相比，该测试速度快，因为检测所需的油量极低（约6 μ g） 。实际失效时间是通过本试验方法获得的值的倍数。当渗透通过一种吸收性结构（如涂有聚乙烯的牛皮纸）时，失效时间将更长且变化，这取决于结构孔隙度和厚度的变化。

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 This standard does not purport to address the safety problems 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 . ====== Significance And Use ====== This test method is valuable in the development and selection of flexible barrier materials suited for use as grease barriers. The test is rapid in comparison with other methods because of the extremely small quantity of oil required for detection (about 6 μ g). 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.
