Scope1.1 This specification covers the classification, compos
3、ition,dimension, and physical properties of mineral fiber (rock, slag,or glass) semi-rigid and rigid board insulation for the use on0F (-18C) cooled surfaces and on heated surfaces up to1800F (982C). Specific applications outside the maximumand minimum temperature limits shall be agreed upon between
4、the supplier and the purchaser.1.2 For satisfactory performance, properly installed protec-tive vapor retarder or barriers shall be used on below ambienttemperature applications to reduce movement of moisturethrough or around the insulation to the colder surface. Failureto use a vapor barrier can le
5、ad to insulation and systemdamage. Refer to Practice C 921 to aid material selection.Although vapor retarder properties are not part of this specifi-cation, properties required in Specification C 1136 are perti-nent to applications or performance.1.3 The orientation of the fibers within the boards i
6、sprimarily 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 orientation that is perpendicular to the principal largesurface (face).1.4 This standard does not purport
7、 to provide the perfor-mance requirements of hourly-rated fire systems. Consult themanufacturer for the appropriate system.1.5 The values stated in inch-pound units shall be regardedas the standard. The SI equivalents of inch-pound units aregiven in parentheses for information only and are approxima
8、te.1.6 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2. Reference

32、ther the insulationshall be supplied plain or with facings and, if faced, shallspecify the type and its requirements. (WarningThe user isadvised that it is possible that the maximum use temperature offacings and adhesives is lower than the maximum use tempera-ture of the insulation. The user shall e
33、nsure that sufficientthickness shall be installed so none of these accessory items(facings and adhesives) are exposed to temperatures abovetheir maximum use temperature.)6.2.2 The vapor retarder facings shall be in accordance withSpecification C 1136.6.2.3 Typical facings are as follows:6.2.3.1 Alum
34、inum foil, reinforced fiberglass scrim, andnatural (brown) kraft paper laminate (facing) is known as FRKor FSK.6.2.3.2 White kraft paper, reinforced fiberglass scrim, andaluminum foil laminate (facing) is known as ASJ (All ServiceJacket).6.2.3.3 Aluminum foil, reinforced fiberglass scrim, andplastic

37、9, the corrosion resulting from insulation incontact with steel plates shall be judged to be no greater thanfor comparative plates in contact with sterile cotton. Test thecomposite insulation material (with facing and adhesive) whena facing is factory adhered by the manufacturer or thefabricator. (W
