SCOPE The materials defined by this specification are thermally moldable calendered PVC compounds that may be used as sound barriers are usually bonded to batt type insulation material. 2. APPLICATION This specification was released originally for materials
3、 used as molded dash insulators, bonded to a reclaimed fiber pad. They were specifically formulated with strength and stiffness properties which would allow direct support of wiring harnesses and other attachment devices without requiring brackets. V ESB-M99GI 27-Al and ESB-M99GI 27-BI were original
4、ly designated V ESB-M99GI 27-A and ESB- M99G127-B, and whenever V ESB-M99GI 27-A and ESB-M99GI 27-B are indicated on engineering drawings, patterns, specifications, etc., the V ESB-M99GI 27-Al and ESB-M99GI 27-BI specifications will be understood to apply. 3. REQUIREMENTS Material specification requ
5、irements are to be used for initial qualification of materials. 3.1 QUALITY SYSTEM REQUIREMENTS Material suppliers and part producers must conform to the Companys Quality System Requirements. 3.2 CONDITIONING AND TEST CONDITIONS All test values indicated herein are based on material conditioned in a
6、 controlled atmosphere of 23 +/- 2 OC and 50 +/- 5 % relative humidity for not less than 24 h prior to testing and tested under the same conditions unless otherwise specified. 3.3 APPEARANCE The barrier material as received, bonded to a reclaimed fiber pad underlay, shall be uniformly smooth, withou
7、t blisters or deep recesses. There shall be no breaks in the vinyl film that would permit any exposure of the underlay material.
