GB/T 22805.1-2008 "Paper and board — Determination of grease resistance — Part 1: Penetration method" specifies the determination of grease resistance of paper and board using the penetration method, which is applicable for testing the penetration ability of grease into paper. The test involves covering a sample over a test cup containing standard grease, recording the time taken for the grease to penetrate through the sample, or observing the degree of penetration after a specified period. The method defines requirements for sample dimensions, test temperature, and grease type, accurately reflecting the paper's ability to resist grease penetration.
