3、08.1. Scope1.1 This specification covers the classification, composition,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
4、 maximumand minimum temperature limits shall be agreed upon betweenthe 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 ins
5、ulation to the colder surface. Failureto use a vapor barrier can lead 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 o
6、r performance.1.3 The orientation of the fibers within the boards 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 orientation that is perpendicular to t
7、he principal largesurface (face).1.4 This standard does not purport 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 u
8、nits aregiven in parentheses for information only and are approximate.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

21、ve.4. Classification4.1 Mineral fiber board insulation covered by this specifi-cation shall be classified into seven types and two categories,shown in Table 1. This classification is based upon theinsulations maximum use temperature, maximum apparentthermal conductivity, minimum compressive resistan
22、ce, maxi-mum linear shrinkage, maximum water vapor sorption, andmaximum surface burning characteristics.4.1.1 Category 1No compressive resistance (load-bearing) properties are required.4.1.2 Category 2Minimum compressive resistance (load-bearing) properties are required.4.1.3 Type V, Grade ARequires
23、 no heat-up schedule.4.1.4 Type V, Grade BHeat-up schedule is required.NOTE 1Caution: Grade B may not be suitable for applicationsrequiring hot installation capability at the maximum temperature indi-cated. In general, products having a Grade B designation are designed tobe used with a heat-up sched
24、ule. Failure to use a heat-up schedule withGrade B products may lead to an exothermic reaction. This is dependenton thickness and temperature.

31、s and Manufacture6.1 CompositionMineral fiber block and semi-rigid andrigid board insulation shall be composed of rock, slag, or glassprocessed from the molten state into fibrous form and bondedwith an organic or inorganic binders or both.Asbestos shall notbe used as an ingredient or component part
32、of the product.6.2 Facings:6.2.1 The purchaser shall specify whether 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
33、the maximum use tempera-ture of the insulation. The user shall ensure 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 withSpecif
34、ication C 1136.6.2.3 Typical facings are as follows:6.2.3.1 Aluminum 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
35、).6.2.3.3 Aluminum foil, reinforced fiberglass scrim, andplastic film (example: polyethylene) laminate (facing) isknown as FSP (Foil-Scrim-Polyethylene).7. Physical Properties7.1 The insulation type shall conform to the followingrequirements in Table 1: maximum use temperature, apparentthermal condu
36、ctivity, compressive resistance, linear shrinkage,water vapor sorption, and surface burning characteristics.7.2 Odor EmissionA detectable odor of objectionablenature recorded by more than two of five panel members shallconstitute rejection of the material when tested in accordancewith 12.8.7.3 Corro
37、siveness to SteelWhen tested and evaluated inaccordance with 12.9, 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 fa
38、cing is factory adhered by the manufacturer or thefabricator. (WarningThere are adhesives that can causecorrosion to steel when they are in contact with water or watervapor and the steel. Currently, there is not a test methodavailable to satisfy every potential corrosion application.)7.4 Stress Corr
