Experimental matrix Prague, Callibration, Measurements - Coggle Diagram
Experimental matrix Prague
Repetition experiments
Ignition times inconclusive:
plates vs rods
(different surface areas)
Full matrix of one set of
experiments to compare with Denmark
Repeat part of matrix with all foil between sample and isolation
Black PMMA 6 mm (compare to MacFP)
Inert material experiments
Edelstahl
With frame
Same as in Denmark
Search for same isolation material
without frame
Isolation material oven: how accurate is the positioning of the thermocouples?
Marcor
Idem to edelstahl
Rods
Only when PMMA rods also conducted in Prague
Inert repetitions
Experiments with PMMA
under nitrogen atmosphere
Black Vs transparent because of bigger difference
Cables
Existing: piloted ignition experiments
CERN
C01: 20, 30 and 50 kW/m^2
C02: 20, 30 and 50 kW/m^2
C04: 20, 3x 30 and 2 x 50 kW/m^2
Cxx: non
TRISTAN
C01: 50 kW/m^2
C02: 50 kW/m^2
C04: 50 kW/m^2
Auto ignition
one cable
full cable
Possible 'new' experiments
Effect of frame
Stop running experiments to check hollowness of sample
Callibration
Daily
Gasanalyzer
Balance
2/week
HRR
Dead time
Before ever experiment
Flux
Measurements
Sample deformation
Use additional camera's to see from more angels
Use reference measurement in image (e.g. ruler)
IR camera
For inert experiments no problem with flame
Look at data taken in Denmark: biggest problem find sample in the image
Temperature measurements for moving samples
