ASTM D-1003 Abrasion Resistance: < 5% <br /> PART 3 EXECUTION <br /> 3.1 EXAMINATION <br /> A. If the substrate preparation is the responsibility of another installer, notify the Architect or <br /> Project Leader of unsatisfactory preparation before proceeding. <br /> B. Glass surfaces should be inspected for defects including scratches or defects which will <br /> affect the final appearance. <br /> C. Do not begin installation until substrates have been properly prepared. <br /> D. If substrate preparation is the responsibility of another installer, notify Architect or Project <br /> Leader of unsatisfactory preparation before proceeding. <br /> E. If the application of a wet glaze attachment system is required, verify that the window film <br /> installation has met the manufacturers recommended guidelines and has passed visual <br /> inspection by the Architect or Project Leader. <br /> 1. An adhesion test may be conducted to the frame surface to verify compatibility. <br /> Adhesion test typically involves the application of a 1-inch-wide by 6-inch-length bead. <br /> Bead is allowed to cure for a minimum 7 days. The applied bead is removed at a 90- <br /> degree angle.The result should be cohesive failure meaning a portion of the product <br /> remains on the surface. If adhesion fails, seek the advice of the manufacturer. <br /> 3.2 PREPARATION <br /> A. Clean surfaces thoroughly prior to installation. <br /> B. Prepare surfaces using the methods recommended by the manufacturer for achieving the <br /> best result for the substrate under the project conditions. <br /> C. If the application of a wet glaze attachment system is required, refer to manufacturers <br /> instruction for surface preparation. <br /> 3.3 FILM INSTALLATION <br /> A. Install in accordance with manufacturer's instructions. Installation must be accomplished by • <br /> a recognized professional installer of film for solar control or safety and security purposes. <br /> Completed work must meet IWFA visual acceptance standard. <br /> 08 87 23-8 <br />
