9、d, alternative methods or solvents shall be used in place of ozone depleting substances. 3.2 Design and construction. This CID is not intended to limit construction to features other than as shown in figures 1 through 7, by dimension, notation, or reference documents. 3.3 Specular reflectivity. With

10、 an angle of incidence of 45 degrees, total reflective light in the visible range shall exceed 50 percent when tested in accordance with SAE J964. 3.4 Range of convexities. Convex mirror shall have an average radius of curvature not less than 20 inches and not more than 60 inches when measured with

11、a spherometer. 3.5 Vibration. The mirror assembly shall show no evidence of damage when subjected to being vibrated for 1 hour in each of its three axes.
