Public Comment No. 6-NFPA 1801-2019 [ Section No. 8.1.4.3 [Excluding any

Sub-Sections] ]



The spatial resolution source target shall consist of two thin, rigid, flat metal surfaces: theemitting surface, and the stencil with the target and 15 cm ± 5 mm × 15 cm ± 5 mm squarecutout. The metal shall be copper for the emitting surface and aluminum for the stencil asdetailed in Figure 8.1.4.3. Each surface shall have dimensions of 3 mm ± 0.5 mm. The front sideof both surfaces shall be painted with flat black paint having a stated emissivity of 0.95 ± 0.03.

Figure 8.1.4.3 Spatial Resolution Source Target.



Statement of Problem and Substantiation for Public Comment

Improve consistency in spatial resolution testing; to exclude more of the background image by making the target larger.

Public Comment No. 1-NFPA 1801-2019 [ Section No. 8.1.4.3.1 ]

8.1.4.3.1

The emitting surface shall be capable of being evenly heated to a surface temperature of 28°C32°C ± 0 1 .5°C 0°C (82°F 90°F ± 1°F 1.8°F ) . The mechanism by which the emitting surfaceis heated shall not be visible to the thermal imager under test. The heating mechanism shall bepermitted to add thickness to the side of the surface that does not face the thermal imagerduring the test.


The Image Recognition TG recommends that we increase the temperature differential between the front and rear panels from 6C to 10C. This change improves the repeatability of the test.

Public Comment No. 3-NFPA 1801-2019 [ Section No. 8.1.4.9 ]

8.1.4.9

The image capturing software and hardware shall permit 16-bit uncompressed color images tobe downloaded from the visible spectrum camera to a computer or memory at a rate of oneimage every 3 seconds ± 0.1 second.


This section is not applicable. It was initially added when some degree of automation in the image processing was being considered. That is no longer the case and this requirement adds unnecessary complication.

8.1.5.3

The spatial resolution source target emitting surface temperature shall be stabilized at 28°C32°C ± 0 1 .5°C 0°C (82°F 90°F ± 1°F 1.8°F ).


The Image recognition TG has determined that increasing the temperature differential between the front and rear plates from 6C to 10C improves the repeatability of the test.







8.1.5.9

A region of interest shall be selected that is equal in size to the warm region of interest. Thissecond region of interest shall be on the opposite side of the directly opposite the warm regionof interest with respect to the center vertical axis of the spatial resolution target from the warmregion of interest . It shall contain ambient temperature pixels only and shall not interfere withthe spatial resolution patterns and shall be labeled A. The image processing software shallapply these regions of interest to all images.


Clarifying precisely where the second region of interest is to be located. Our round robin testing indicated that SR results will vary depending on where the second region of interest is drawn on the target. This clarification will improve consistency in the test results.

8.1.5.10 *

Two separate pixel smoothing filters shall be applied to the regions of interest. A movingaverage in two dimensions shall be applied to the regions of interest, with the average having aperiod equal to the width the horizontal distance and height vertical distance of the thermalthe thermal imager display pixels observed in the captured images. It shall be labeled the 1Xfilter. A second filter shall be applied in the same manner as the 1X filter but with a period fourtimes greater and shall be labeled the 4X filter. Both filters shall be applied to the original image;the resulting images shall be labeled W1X, W4X, A1X and A4X, and shall be storedindependently for further calculation.


The intent of this section is to measure the distance from the edge of pixel 1 to the edge of pixel 2 (the pixel frequency), taking into account the "white space" between the pixels. We do not want the dimensions of the pixel itself.
