4. Mock-up with steep slope
Test result(1)
Mock-up with steep slope
☞ The temperature reached to 800℃ within 30 seconds,
maintained 800 ~ 1100 ℃ for 2 minutes.

5. Mock-up with easy slope
Test result(2)
Mock-up with easy slope
☞ All temperatures reached to 800℃ within 30 seconds,
maintained 800 ~ 1100 ℃ for 2 minutes.

6. Test result(3) Tunnel shape mock-up
In case of Tested-Device with a tunnel shape, there is no sufficient air flow result in low temperature. This local part should be excluded when measuring the temperature entirely. So, all temperature sensors should be installed at a height of 50 mm ± 10 mm below the lowest point of the Tested-Device's external surface.

7. Conclusion
KATRI Proposal
All temperature sensors shall be installed at a height of 50 mm ± 10 mm below the lowest point of the Tested-Device's external surface when oriented as described in At least one temperature sensor shall be located at the center of Tested-Device, and at least 4 temperature sensors shall be located within 100 mm from the edge of the Tested-Device towards its center with nearly equal distance between the sensors.
