(Practice)Standard Practice for Tests of Cleanroom Materials
Standard Practice for Tests of Cleanroom Materials
SIGNIFICANCE AND USE
5.1 This practice is not intended to advocate or discourage use of any particular test method. It is intended for information only, and to provide a useful guide for further detailed study, test, and evaluation of cleanroom materials and products.
SCOPE
1.1 This practice identifies test methods used to evaluate the properties of various materials and products used in cleanrooms and for cleanroom construction.
1.2 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.
1.3 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.
