21、rea, shall be cause for rejection.7.2.6.2 PliabilitySpecimens tested in accordance with thetest procedure in 10.2 shall not show cracking or delamination.This test does not apply to materials that are not flexible andnot intended to be bent or flexed.7.2.7 Mold and Mildew Fungal resistance of sheet
22、radiantbarriers shall be tested in accordance with Test Method C 1338.The samples are then examined visually under 53 magnifica-tion for the extent of mold growth and for indications ofdeterioration. Evidence of mold growth beyond the inoculationarea shall be cause for rejection.8. Significance and
23、Use8.1 This specification recognizes that the effectiveness of asheet radiant barrier is dependent on proper installation.Practice C 1158 addresses use and installation of radiantbarriers.8.2 This specification identifies the material properties thatare important for sheet radiant barrier products.

25、ormed in accordance with Prac-tice C 390.10. Test Methods for Adhesive Performance10.1 Bleeding and Delamination:10.1.1 ScopeThis test method covers the determination ofbleeding and delamination of sheet radiant barriers.10.1.2 Significance and UseIt is necessary that sheetradiant barriers not show
26、adhesive bleeding or delaminationsince these conditions could result in a loss of structuralintegrity, a change in water vapor permeability, or an increasein surface emittance.10.1.3 SamplingA minimum of three specimens of theradiant barrier material with dimensions of approximately 7.62by 15.24 cm

28、sivehas bled or extruded through the surface or if separation of foilfrom the substrate (delamination) has occurred. Estimate thepercentage of the area that has delaminated.10.1.5 Precision and BiasPrecision and bias have notbeen determined for this qualitative test.10.2 Pliability:10.2.1 ScopeThis
29、test method covers the determination ofcracking or delamination of the radiant barrier due to folding orbending.
