2、on or, in the case of revision, the year of last revision. A number in parentheses 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.

3、1. Scope1.1 This specification covers the composition, dimensions, and physical properties of mineral fiber (rock, slag, or glass) metalmesh covered and industrial type blanket and blanket-type pipe insulation (typically on 24 in. (610 mm) diameters or larger). Itsuse is for cooled surfaces at tempe

4、ratures operating below ambient to 0F (18C) and on heated surfaces on expansion joints tolarge diameter vessels and tanks operating at temperatures up to 1200F (649C). Specific applications outside the actual usetemperatures shall be agreed upon between the manufacturer and purchaser.1.2 For satisfa

5、ctory performance, properly installed protective vapor retarders or barriers shall be used on below ambienttemperature applications to reduce movement of moisture/water vapor through or around the insulation towards the colder surface.Failure to use a vapor retarder can lead to insulation and system

6、 damage. Refer to Practice C921 to aid material selection.Althoughvapor retarder properties are not part of this specification, properties required in Specification C1136 are pertinent to applicationsor performance.1.3 The orientation of the fibers within the blanket is primarily parallel to the hea

7、ted surface. This specification does not coverfabricated pipe and tank wrap insulation where the insulation has been cut and fabricated to provide fiber orientation that isperpendicular to the heated surface.1.4 This standard does not purport to provide the performance requirements of hourly-rated f

8、ire systems. Consult themanufacturer for the appropriate system.1.5 See Supplementary Requirements for modifications to sections in this standard only when specified by purchaser in thecontract or order from the U.S. Military specifications utilized by the U.S. Department of Defense, Department of t

9、he Navy, andthe Naval Systems Command.1.6 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematicalconversions to SI units that are provided for information only and are not considered standard.1.7 This standard does not purport to address

10、 all of the safety concerns, if any, associated with its use.
