21、e vapor retarder.8.3 There shall be no defects that would affect ability of userto process material.9. Significance and Use9.1 Entrapment of water in thermal insulation caused bycondensation of water vapor that has penetrated into theinsulation is detrimental to the thermal resistance of theinsulati

22、on. For this reason, in certain installations wheretemperature and moisture conditions have the potential tocreate a vapor driving force toward the insulation, a deterrentto the passage of such vapor into the installed insulation needsto be provided. This is the primary function of the vaporretarder

23、.9.2 In addition to the function stated in 9.1, a vapor retarderhas the potential to provide physical protection and addedstrength to the insulation system.9.3 This specification is used to specify material by physicalproperty requirements that address the above prerequisites. Thedesigner of an insu

24、lation system, after determining the degreeof protection needed for the insulation, can use this specifica-tion to specify the appropriate type of vapor retarder when oneis required.10.

PERMEANCE UNDER OTHER THAN STANDARD TEST CONDITIONSX1.1 Transmission of water vapor through a vapor retarderis induced by a vapor pressure differential between sides of thevapor retarder, caused by different conditions of relativehum

45、idity from side to side.X1.2 The resistance of materials to the passage of watermay change under varying vapor driving conditions, such ashigher or lower temperatures, higher or lower relative humiditydifferentials, or like differentials at different ranges (that is,50/0 % RH as opposed to 75/25 %RH

46、).X1.3 For purposes of this specification, a standard testcondition is used, that of 73F (23C) with 50 % relativehumidity on one side and 0 % relative humidity on the other.X1.4 It is conceivable that a material that meets a require-ment for permeance under the test conditions of the specifica-tion

47、may not be adequate under actual conditions of use.X1.5 Since varying test conditions or conditions of use mayaffect performance (in this or any physical testing), a user maydeem it necessary to evaluate a vapor retarder for permeanceunder conditions more closely approximating actual serviceconditio
