Scope1.1 This specification
3、 covers mineral fiber insulation pro-duced to form hollow cylinders for standard pipe and tubingsizes. The mineral fiber pipe insulation may be molded orprecision v-grooved, with one or more walls split longitudi-nally for use on pipe temperatures up to 1400F (760C).1.2 For satisfactory performance,
4、 properly installed protec-tive vapor retarders or barriers should be used on sub-ambienttemperature applications to reduce movement of moisturethrough or around the insulation to the colder surface. Failureto use a vapor barrier can lead to insulation and systemdamage. Refer to Practice C921 to aid

22、 onthickness and temperature. Consult the manufacturer or manufacturersliterature for special heat rate considerations.4.2 Binder decomposition at elevated temperature may be alimiting factor in certain applications. Consult the manufac-turer regarding special heat rate considerations.5. Materials a

The specifier shall ens
25、ure that sufficientinsulation thickness is installed so none of these accessory items (facingsand adhesives) are exposed to temperatures above their maximum usetemperature. The products covered by this standard are predominantlyinorganic in nature. Organic facings, adhesives and binders are also use

36、tion.11.1.3.2 Practice C1058 may be used to obtain recom-mended test temperature combinations for testing purposes.11.1.3.3 As specified in C1045, the range of test conditionsmust include at least one test where the hot surface temperatureis greater than, or equal to, the hot limit of the temperatur
37、erange of desired data and at least one test where the coldsurface temperature is less than, or equal to, the cold limit ofthe temperature range desired. At least two additional testsshall be distributed somewhat evenly over the rest of thetemperature range.11.1.3.4 Final analysis of the thermal dat
38、a shall be con-ducted in accordance with C1045 to generate a thermalconductivity versus temperature relationship for the specimen.11.1.3.5 The final step of C1045 analysis is to calculate thethermal conductivity using the equations generated at a set ofmean temperatures for comparison to thespecific
39、ation.WarningWhile it is recommended that thespecification data be presented as thermal conductivity versustemperature, several existing specifications may contain meantemperature data from tests conducted at specific hot and coldsurface temperatures. In these cases, the conductivity as afunction of
40、 temperature from the C1045 analysis may providedifferent results. To insure that the data is compatible, a C680analysis, using the thermal conductivity versus temperaturerelationship from C1045 and the specific hot and cold surfacetemperatures, is required to determine the effective thermalconducti
