Cleanability Rating 3 min 3.5 ENVIRONMENTAL TESTING SAMPLE PREPARATION All parts shall be fully trimmed including all components packaged in the environment (eg. speakers, hardware,
11、 wiring, etc.) and assembled onto actual or representative production support foundations. This includes not only all attaching points, but also any boundary conditions that may restrict movement, unless otherwise specified by the affected Materials Engineering Activity. The retention methods, attac
12、hments, and supporting garnish moldings (if any), shall be the same as proposed for production. MEASUREMENT LOCATIONS . Every twenty centimeters AND AT THE POINTS OF GREATEST MOVEMENT BETWEEN THE TWENTY CENTIMETER MARKS along the parts outside edges and internal openings or defined by PD Engineering
13、. . The “significant characteristics locations“ specified on the engineering drawing. MEASUREMENT TECHNIQUE The movement at each measurement point shall be recorded in two directions: (1) in the x/y plane from the observers view, and (2) in the z-dimension direction into or out of the x/y plane from
14、 the observers view. The observers view shall remain consistent always viewing from the front side of the part.
