Flux profile procedure:

1)Measure flux at 410 mm point (5.1±0.2kw/㎡)

2)Fluxmeter 2-3 mm above surface

3)Measure flux after 30 s

4)Measure at 110,210,...910 points

5)Criteria on all 9 points

6)Recheck 410 mm position

7)Remove dummy specimen and close door.Wait 5 mins then read chamber temperature and pyrometer

Flux profile procedure:

1)Measure flux at 400 mm point (4.8-5.2kw/㎡)

2)Fluxmeter 1.6-3.2 mm above surface

3)Measure flux after (30±10) s

4)Measure at 100,200,...900 points

5)Criteria on 200,400 and 600 points ONLY

6)Recheck 410 mm position

7)Slide door open to remove dummy specimen. Wait 30 mins then read chamber temperature and pyrometer

Daily Check:

Test Procedure:

1)Light piout burner at least 50 mm away from zero point

2)Push specimen into chamber (time 0)

3)120s: put pilot is place (flame at 10 mm position)-exposure for 10 mins

4)720s: remove pilot burner and turn off flames

5)1800s: finish test

Test Procedure:

1)Light piout burner at least 50 mm away from zero point

2)Push specimen into chamber (time 0)
