ASTM F21-20<\/h3>\n

Active Standard: Standard Test Method for Hydrophobic Surface Films by the Atomizer Test<\/h4>\n
\n

ASTM F21<\/h4>\n

Scope<\/strong><\/p>\n

\n

1.1<\/span> This test method covers the detection of the presence of hydrophobic (nonwetting) films on surfaces and the presence of hydrophobic organic materials in processing environments. When properly conducted, the test will enable detection of fractional molecular layers of hydrophobic organic contaminants. On very rough or porous surfaces, the sensitivity of the test may be significantly decreased.<\/p>\n<\/p><\/div>\n

\n

1.2<\/span> Units\u2014<\/span>The values stated in SI units are to be regarded as standard. The values given in parentheses after SI units are provided for information only and are not considered standard.<\/p>\n<\/p><\/div>\n

\n

1.3<\/span> 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.<\/i><\/p>\n<\/p><\/div>\n

\n

1.4<\/span> This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.<\/i><\/p>\n<\/p><\/div>\n
