Section 484D.265 - Specifications for emblem1. The emblem must be entirely visible in daylight and at night from all distances between 600 feet and 100 feet (182.88 meters to 30.48 meters) from the rear when directly in front of lawful upper beam of headlamps.3. The spectrophotometric color values of the yellow-orange fluorescent material must have a dominant wave length of 590-610 millimicrons and a purity of 98 percent before test. After the durability test required by subsection 2 of NAC 484D.270, the dominant wave length of the fluorescent material must not change more than 10 percent.4. The reflective material must have minimum intensity values at each of the angles listed in this subsection. After the durability test, the minimum reflective intensity values for the reflective material must not change more than 20 percent from the following values: | Minimum Reflective Intensity Values. R |
| | |
| Divergence | Incidence | Reflective |
| Angle, Deg | Angle, Deg | 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 must 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 square inches (322.6, ± 32.3 square centimeters) of reflective material. The maximum dimension of the test surface must not be greater than 1.5 times the minimum dimension. The reflective intensity (R) is computed from the equation.

| (Lr) (d) |
| R = | _______ |
| (Ls) (A) |
where
R = reflective intensity, candlepower per incident foot-candle per square foot
Lr = illumination incident upon receiver at observation point, foot-candles
Ls = illumination incident upon a plane perpendicular to the incident ray at the test specimen position, foot-candles
d = distance from test specimen to source of illumination (100 ft. as specified in SAE J594), feet
A = area of test surface, square feet
5. The reflective and fluorescent materials must be tough, flexible and of sufficient thickness and strength to meet the requirements of this section and NAC 484D.270. After the durability test, the fluorescent and reflective material must show no appreciable discoloration, cracking, crazing, blistering, loss of durable bond or dimensional change.6. Backing material for portable identification emblems must be equivalent to 0.040 in. (0.1016 millimeters) minimum thickness aluminum, 22-gauge (0.030 in. or 0.76 mm) minimum thickness mill-galvanized or coated sheet steel with the surface clean and receptive to a durable bond. The backing material must be free of burrs.Nev. Admin. Code § 484D.265
