The module is provided in subassemblies. 4.1.3 Incorporation of a module into the final assembly does not require any alteration of the module from its originally evaluated form. If YES, specific details describing necessary modification(s) are provided in the installation instructions. 4.1.4 If the module must bear a definite relationship to another module, it is constructed to permit incorporation into the final assembly without the need for alteration. 4.1.5 The construction of the module is such that ground continuity is not interrupted by installation. 4.1.6 arts of the module are prevented from loosening or turning, if such loosening or turning may result in a risk of fire, electric shock, or injury to persons. 4.1.7 Friction between surfaces is not used as the sole means to inhibit the turning or loosening of a part. 4.1.8 Any adjustable or movable structural part is provided with a locking device to reduce the likelihood of unintentional movement. 4.2 Metal parts Metals used in locations that are exposed to moisture shall not be employed alone or in combinations that could result in deterioration, such that the product would not comply with the requirements in this standard. Iron or mild steel serving as a necessary part of the module but not exposed to the weather are plated, painted, or enameled for protection against corrosion. Simple sheared or cut edges and punched holes are not required to be additionally protected. No 5 OLYMERIC MATERIALS

Both backsheets have identical chemical, electrical and physical properties. Due to engineering decision only the V-BS MGEW- SbR backsheet was tested. The testing on the black patterned back sheet BS V-BS MGEW-SbR was omitted since it was considered less critical all black version.

Both backsheets have identical chemical, electrical and physical properties. Due to engineering decision only the V-BS MGEW- SbR backsheet was tested. The testing on the black patterned back sheet BS V-BS MGEW-SbR was omitted since it was considered less critical all black version.
