Section 205 IAC 1-5-3 - Color and reflectivity requirements

Authority: IC 9-21-9-5

Affected: IC 9-21-9

Sec. 3.

Color and reflectivity.

(1) The spectrophotometric color values of the yellow-orange fluorescent material shall have a dominant wave length of 590610 millimicrons and a purity of 98 percent before test. After Durability Test, paragraph 6.2, the dominant wave length of the fluorescent material shall not change more than 10 percent.
(2) The reflective material shall have minimum intensity values of each of the angles listed per Table 1. After Durability Test, paragraph 6.2, the minimum reflective intensity values for the reflective material shall not change more than 20 percent from the values specified in Table 1.

TABLE 1- MINIMUM REFLECTIVE INTENSITY VALUES, R*

Divergence Angle, deg Incidence Angle, deg Reflective Intensity, R
0.2 0 10
0.2 15 7
0.2 30 5
0.5 0 5
0.5 15 4
0.5 30 2

* [Measurements shall be conducted in accordance with photometric testing procedures for reflex-reflectors as specified in Society of Automotive Engineers Standard, SAE J594, Reflex Reflectors, and using 50, ± 5 sq. in. (322.6, ± 32.3 sq. centimeters) of reflective material. The maximum dimension of the test surface shall not be greater than 1.5 times the minimum dimension. The Reflective Intensity (R) is computed from the equation.]
