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. It is the responsibilityof the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatoryrequirements prior to use.2.

34、 covered blanket is secured with tie-wires or metal stitching.Asbestos shall not be used as an ingredient or component part of the product.6.2 Facings:6.2.1 Types of facings for one or both sides of blanket units shall be specified. When both sides are to be faced, units arepermitted to have the sam
35、e or different types on the two sides.6.2.1.1 The user of this specification is advised that the maximum use temperature of some facings and adhesives will be lowerthan the maximum use temperature of the insulation. For example, usually galvanized hexagonal wire-woven netting and tie wiresor stitchi
36、ng perform well under continuous exposure to temperatures up to 392F (200C). Exposure to temperatures above thislimit will cause the outer free zinc layer to peel. Though there are potential or occasional concerns for corrosion conditions atvarious temperatures, galvanized wire, stitching, or facing

Inaddition, the user of this specification shall ensure that sufficient insulation thickness is installed so that none of the accessory items(facings, adhesive, coatings, and lagging) are exposed to temperatures above their maximum use temper
