2、 indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the U.S.Department of Defense.1.Scope1.1 This specification covers the composition,sizes,dimensions,and physical pro
3、perties of cellular glass thermalinsulation intended for use on surfaces operating at tempera-tures between 450 and 800F(268 and 427C).It is possiblethat special fabrication or techniques for pipe insulation,orboth,will be required for application in the temperature rangefrom 250 to 800F(121 to 427C
4、).Contact the manufacturerfor recommendations regarding fabrication and applicationprocedures for use in this temperature range.For specificapplications,the actual temperature limits shall be agreed uponbetween the manufacturer and the purchaser.1.2 It is anticipated that single-layer pipe insulatio
