k value from table 4 0.94
Hence k = 0.94
Oxygen index value OI = C
F
+ kd
d is oxygen concentration increment
OI = 35.0 + (0.94 x 0.2)
Oxygen index value = 35.2 (to one decimal place for reporting)
= 35.19 (to two decimal places, for calculation of and verification
of d as required in Part 3)
Standard Deviation = 0.15 Therefore, the test result is valid.
Part 3 – Burning characteristics of the material
No
relevant ancillary characteristics or behaviour such as, charring, dripping, severe shrinkage, erratic
burning, or after-glow were observed during the test.
