Terminology3.1 The definitions in Terminology C 168 shall apply to theterms used in this specification.3.2 Definitions of Terms Specific to This Standard:3.2.1 moldedrefers to products preformed via a moldingprocess to yield full-round cylindrical pipe insulation sections.3.2.2
18、precision v-grooverefers to products fabricated frommachined board via a precision cutting process. Machinedsegments are adhered to a backing to form a full-roundcylindrical pipe insulation section. Due to the precision of theprocess, the product has no gaps when installed.4. Classification4.1 Produ
19、cts covered by this specification are classifiedaccording to maximum use temperature as follows:4.1.1 Type IMolded, for use to 850F (454C).Grade ARequires no heat-up scheduleGrade BHeat-up schedule is required4.1.2 Type IIMolded, for use to 1200F (650C).Grade ARequires no heat-up scheduleGrade BHeat

21、0F (760C)Grade ARequires no heat-up scheduleGrade BHeat-up schedule is requiredNOTE 1Warning: Grade B may not be suitable for applicationsrequiring hot installation capability at the maximum temperature indi-cated. Products having a Grade B designation are designed to be used witha heat-up schedule.
22、 Failure to use a heat-up schedule with Grade Bproducts may lead to an exothermic reaction. This is dependent onthickness and temperature. Consult the manufacturer or manufacturersliterature for special heat rate considerations.4.2 Binder decomposition at elevated temperature may be alimiting factor
23、 in certain applications. Consult the manufac-turer regarding special heat rate considerations.5. Materials and Manufacturer5.1 Composition The mineral fiber insulation for pipesshall be manufactured from mineral substance such as rock,slag, or glass, processed from a molten state into fibrous formw
24、ith binder. Asbestos shall not be used as an ingredient orcomponent part. Some products may also contain adhesive.5.2 Jackets (Facings)The user of this specification has theoption to specify that the insulation be jacketed.NOTE 2The user is advised that the maximum use temperature offactory-applied
25、facings and adhesives may be lower than the maximumuse temperature of the insulation. The specifier shall ensure that sufficientinsulation thickness is installed so none of these accessory items (facingsand adhesives) are exposed to temperatures above their maximum usetemperature. The products cover
26、ed by this standard are predominantlyinorganic in nature. Organic facings, adhesives and binders are also usedin the construction of these products. The resulting composite thereforecould have increased combustibility.6. Physical Requirements6.1 The product shall conform to the following require-men
27、ts in addition to those specified in Table 1.6.2 Hot Surface Performance:6.2.1 The product shall not crack, warp, flame, or glowduring hot surface exposure. No evidence of melting or fiberdegradation shall be evident upon post test inspection.6.2.2 The insulations internal temperature rise (exotherm
28、)shall not exceed the pipe temperature by more than 200F(111C).6.3 Non-fibrous (Shot) Content:6.3.1 The non-fibrous content of a rock- or slag-basedproduct shall not exceed 30 % by weight.6.4 For Naval Sea Systems Command (NAVSEA) accep-tance, materials must also comply with Supplemental Require-men
29、ts. See Annex A1 of this standard.7.

32、 joints.8.3 The inner and outer bore of the insulation shall beconcentric to the outer surface. The deviation from concentric-ity shall not exceed316 in. (5 mm).9. Workmanship9.1 The insulation shall not have defects that will adverselyaffect installation or service quality.10. Sampling10.1 When spe
33、cified in the purchase order or contract,sampling and acceptance shall be in accordance with PracticeC 390.5Available from Underwriters Laboratories of Canada, 7 Crouse Road, Scarbor-ough, Ontario MIR3A9.C54707211. Test Methods11.1 The properties in this specification shall be determinedin accordanc
34、e with the following test methods, with jacketingexcluded unless stated otherwise.11.1.1 Density and DimensionsTest Method C 302.11.1.2 Linear Shrinkage Test Method C 356.11.1.3 Thermal ConductivityTest Method C 335.11.1.3.1 Thermal performance shall be characterized on a3-in. NPS 3 2-in. pipe insul
35、ation size. Thermal performancemust be assessed on actual pipe insulation sections. Dataobtained on flat samples, using Test Method C 177, shall not beused to state compliance with this specification.11.1.3.2 Practice C 1058 may be used to obtain recom-mended test temperature combinations for testin
36、g purposes.11.1.3.3 As specified in C 1045, 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 temperaturerange of desired data and at least one test where the coldsurface temperature is less than, or equal t
37、o, 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 data shall be con-ducted in accordance with C 1045 to generate a thermalconductivity versus temperature re
38、lationship for the specimen.11.1.3.5 The final step of C 1045 analysis is to calculate thethermal conductivity using the equations generated at a set ofmean temperatures for comparison to thespecification.WarningWhile it is recommended that thespecification data be presented as thermal conductivity
39、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 temperature from the C 1045 analysis may providedifferent results. To insure that the data is compat
40、ible, a C 680analysis, using the thermal conductivity versus temperaturerelationship from C 1045 and the specific hot and cold surfacetemperatures, is required to determine the effective thermalconductivity for comparison to the specification requirements.11.1.4 Water Vapor SorptionTest Method C 110
