LUMINANCE TEST

 

Material Tested: Kryptaglow® Paint Layer identified by Co-Leash Inc. as consisting of three

coats: (i) Kryptaglow White Latex Base Coat # 1171, (ii) 3 Coats of Kryptaglow Paint # 1300C,

and (iii) Kryptaglow Clear Protective Top Coat # 1102, and listed in the table below as Material C.

Test Conditions:

1. The test was performed in a windowless laboratory room by the contact method (ISO 17398:2004(E), para. 7.11.6.3).

 

2. Test sample excitation: 21.60±0.02 lx along the entire sample surface during 120 min for each sample.

 

3. Excitation System.

 

3.1. The excitation light source: Fluorescent Double Linear 13 W Lamp of the 410 nm - 670 nm quasicontinuous spectrum

with two parallel linear light tubes 120 mm long, 11.5 mm in diameter, with the interaxial distance of 13.5 mm, located

in the same horizontal plane. The tube holding fixture is equipped with two sliding black screens that control the part of

the tube length, the light from which is directed toward the sample under test. The fixture is connected to the lamp

pedestal with a system of fixable levers that allows the motion of the light tube holder parallel to itself in the vertical

direction to vary the distance between the sample surface and the tube plane from 160 mm to 1,000 mm.

 

3.2. The excitation system was covered with a pressboard box of the dimensions (mm) of 180×180×1,100 with a vertical

slit along one side that allowed the motion of the fixable levers to vary the distance between the light source and the

sample surface. In our experiments, the angle of vision of the sample from the light source location was close to 5.7°; with

the open light source dimensions close to 25 mm by 25 mm, the theoretical uniformity of the illuminance of the entire

sample surface was achieved, which was confirmed by the illuminance measurements.

 

4. The test consisted of three 240-minute (120 min excitation/90 min phosphorescent luminance measurements, 30 min

waiting period) cycles. The waiting period is related to the difference in duration of the excitation and the luminance parts

of the cycle.

5. The test samples were preconditioned per ISO 17398:2004(E), para. 7.11.2. for ninety six hours. The sample luminance

measured prior to the test cycle was on the level of the luminance meter zero noise.

Conclusions: 1. The material tested meets the requirements of NYC DOB RS 6-1A, para. 1.4.

2 The Brightness Rating of the material tested is: 42-14-9.

 

 

 

TEST DESCRIPTION

 

1. The test per NYC DOB RS 6-1A, para. 1.0 - 1.4. Test conditions: T=22°C, RH=40%, P=101.6 kPa.

 

2. After 120-min excitation period, the sample was removed from the excitation chamber (in the darkened room) and put on

the laboratory table; the luminance detector was installed upon the sample center, and the luminance test chamber of the

inner dimensions (mm) of 258×208×164 and the wall/top thickness of 12 mm was used to cover the sample/detector pair to

prevent any uncontrolled irradiation of the sample.

 

3. The experimental error, evaluated on the basis of the data related to the illuminance process and the results of the

luminance measurements on a standard reference material by the partial derivatives and least squares methods, does not

exceed 6%. The data on the standard deviation are kept on file at CIEMS. To concentrate the numerical information for

statistical considerations, a set of the luminance measurements on each of the samples tested was performed at the end of

ten-minute intervals from 10 min to 100 min from the moment of the illuminance process completion.

4. INSTRUMENTS AND DEVICES USED

5. The standard reference material used for the test setup calibration:

- Absolute Black-Body Radiator Model 9291L HMI with Platinum Wire Radiator - luminance measurements

- Standard Candle with Optical Bench Model 47496 Sci. Kit & Boreal Labs. - illuminance.

 

6. The equipment used in the test meets the applicable NIST, ASTM, ASME, OSHA and State requirements and was

calibrated with the standards traceable to the NIST. The calibration was performed per ANSI/ASQC M1-1996,

ANSI/ISO/ASQ Q9004-2000, ISO 10012:2003, ISO 5725-2:1994, MIL-STD-45662, MIL-I-45208, NAVAIR-17-35-

MTL-1, CSP-1/03-93, and the instruments manufacturers' specifications.
