SCOPE The materials defined by this specification is heat expanding mastic sheet deadeners. 2. APPLICATION: ESB-M5G30-A2 specification was originally released for 1987 program applicati
3、ons that do not require testing per the flammability lot sampling plan. This material should be installed over electrocoated or primed metal surfaces before guide coat is applied. Proper expansion and bonding occurs during guide coat and enamel oven exposure at metal temperatures between 135 and 163
4、 C. To attain good adhesion, the exposure time must be greater than 8 minutes for the lower 135 C metal temperature. 3. REQUIREMENTS: Material specification requirements are to be used for initial qualification of materials. 3.1 QUALITY SYSTEM REQUIREMENTS Material suppliers and part producers must
5、conform to the Companys Quality System Requirements. 3.2 INFRARED SPECTROPHOTOMETRY AND/OR THERMAL ANALYSIS IR spectra and thermograms established for initial approval shall constitute the reference standard and shall be kept on file at the designated material laboratory. All samples shall produce I
6、R spectra and thermograms that correspond to the reference standard when tested under the same conditions. 3.3 CONDITIONING AND TEST CONDITIONS All test values indicated herein are based on material conditioned in a controlled atmosphere of 23 +/- 2 C and 50 +/- 5 % relative humidity for not less th
7、an 24 h prior to testing and tested under the same conditions unless otherwise specified.
