Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the Department of Defense.1. Scope1.1 This specification covers the composition, size, dime

3、n-sions, and physical properties of glass fiber blanket thermal andacoustical insulation for use up to 700F (370C) in aircraftapplications. For specific applications, the maximum tempera-ture shall be agreed upon between the supplier and thepurchaser.1.2 The values stated in inch-pound units are to

4、be regardedas standard. The values given in parentheses are mathematicalconversions to SI units that are provided for information onlyand are not considered standard.1.3 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of t

5、he user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.
