1、Designation: C 553 08Standard Specification forMineral Fiber Blanket Thermal Insulation for Commercialand Industrial Applications1This standard is issued under the fixed designation C 553; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revi
2、sion, 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 Department of Defense.1. Scope1.1 This specification
3、covers the classification, composition,physical properties, and dimensions of mineral fiber (rock,slag, or glass) blanket intended for use as thermal insulation onsurfaces operating at temperatures between 0F (-18C) and1200F (649C). For specific applications, the actual tempera-ture limits shall be
4、agreed upon between the supplier and thepurchaser.1.2 The orientation of the fibers within the blanket isprimarily parallel to the principal surface (face). This specifi-cation does not cover fabricated pipe and tank wrap insulationwhere the insulation has been cut and fabricated to provide afiber o
5、rientation that is perpendicular to the surface (face).1.3 For satisfactory performance, properly installed protec-tive vapor retarders must be used in below ambient temperatureapplications to reduce movement of water vapor through oraround the insulation towards the colder surface. Failure to usea
6、vapor retarder can lead to insulation and system damage.Refer to Practice C 921 to aid material selection. Althoughvapor retarders are not part of this specification, propertiesrequired in Specification C 1136 are pertinent to application orperformance.1.4 This standard does not purport to provide t
7、he perfor-mance requirements of hourly-rated fire systems. Consult themanufacturer for the appropriate system.1.5 The values stated in inch-pound units are to be regardedas standard. The values given in parentheses are mathematicalconversions to SI units that are provided for information onlyand are
8、 not considered standard.1.6 This standard does not purport to address all of thesafety concerns associated with its use. It is the responsibilityof the user of this standard to establish appropriate safety andhealth practices and determine the applicability of regulatorylimitations prior to use.2.
