Scope1.1 This specification co
3、vers 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 ag
4、reed 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 ori
5、entation 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 va
6、por retarder can lead to insulation and system damage.Refer to Practice C921 to aid material selection. Althoughvapor retarders are not part of this specification, propertiesrequired in Specification C1136 are pertinent to application orperformance.1.4 This standard does not purport to provide the p
