Scope1.1 This specification covers mineral fiber therma
3、l insulat-ing materials in the form of dry cement, which, when mixedwith a suitable proportion of water, applied as a plastic mass,and dried in place, affords resistance to heat transmission onsurfaces operating at temperatures between 250 and 1900F(about 121 and 1038C).1.2 The values stated in inch
4、-pound units are to be regardedas standard. The values given in parentheses are mathematicalconversions to SI units that are provided for information onlyand are not considered standard.1.3 The following safety hazards caveat pertains only to thetest methods section of this specification: This stand

Qualification Requirements6.1 The following requirements are employed for purposesof initial material o
16、r product qualification:6.1.1 Linear shrinkage, and6.1.2 Dry adhesion to steel.7. Sampling7.1 The cement shall be sampled, for the purpose of tests,using one of the following procedures. Unless otherwisespecified or agreed upon between the purchaser and themanufacturer or supplier, the cement shall
17、be sampled usingthe manufacturers standard procedure.7.1.1 Use Criteria C390. Each bag shall represent a unit.7.1.1.1 In a single sampling plan by attributes the accept-ability of a lot will be determined by the number of units ofproduct in the sample that do not conform to the specifications.The ac
18、ceptable quality level (AQL) and limiting quality level(LQL) of an acceptance sampling plan, expressed as percent-ages of the units nonconforming, are characteristics of thesampling plan and are not to be viewed as product specifica-tions.7.1.2 Use the average of the test data from the number oftest
19、 specimens required by the appropriate test method torepresent the average for the entire lot.7.2 The specimen for test is to be taken from the middle ofa bag, so as to be representative of material from the entire bag.8. Number of Tests and Retests8.1 If the average of the test data obtained using
20、7.1.2 failsto conform to the requirements of this specification, a secondsample shall be taken from the lot. Average the results of theretest with the results of the original test to determine compli-ance with this specification.9. Specimen Preparation9.1 Mix cement with water and mold, cure, dry, a
21、nd cut inaccordance with Practice C163, to produce the appropriate sizeand shape specimens for testing as specified below.10.

22、y10.4.1 The thermal conductivity as a function of tempera-ture for the representative specimens shall be determined withdata obtained from a series of thermal tests utilizing testmethods C177, C518,orC1114 as appropriate for the materialunder study. Specimen shall be tested at a maximum thicknessof
23、112 in. (38 mm).10.4.1.1 Test Method C518 shall not be used at tempera-tures or resistances other than those in the range of thecalibration.10.4.1.2 Test Method C1114 shall not be used at tempera-tures or resistance ranges other than those with comparableresults to Test Method C177.10.4.2 The test m
24、ethod selected shall have proven correla-tion with Test Method C177 over the temperature range ofconditions used. In cases of dispute, Test Method C177 shall beconsidered as the final authority for material having flatgeometry.10.4.3 Practice C1058 shall be used to obtain recommendedtest temperature
25、 combinations for testing purposes.10.4.4 As specified in Practice C1045, the range of testconditions must include at least one test where the hot surfacetemperature is greater than, or equal to, the hot limit of thetemperature range of desired data and at least one test wherethe cold surface temper
26、ature is less than, or equal to, the coldlimit of the temperature range desired. Additional tests, at leasttwo, shall be distributed somewhat evenly over the rest of thetemperature range.10.4.5 Conduct the final analysis of the thermal data inaccordance with Practice C1045 to generate a thermal cond
27、uc-tivity versus temperature relationship for the specimen.10.4.6 The final step of Practice C1045 analysis is tocalculate the thermal conductivity using the equations gener-ated at a set of mean temperatures for comparison to thespecification. WarningWhile it is recommended that thespecification da
28、ta 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 thermal conductivityas a function of temperature from the Practice C1045 analysismay prov
29、ide different results. To insure that the data iscompatible, a Practice C680 analysis, using the thermal con-ductivity versus temperature relationship from Practice C1045and the specific hot and cold surface temperatures, is requiredto determine the effective thermal conductivity for comparisonto th
