Preliminary test

The estimated auto-ignition temperature was 470°C.

Main study

Ignition of the test item within 5 min after introduction was observed with each sample volume and with each test a minimum auto-ignition temperature was obtained. The maximum deviation between the three values was < 20°C. According to the guidelines, no further testing was required.

The lowest temperature at which ignition of the test item occurred was 471°C. This temperature was rounded down to the nearest multiple of 5°C giving an auto-ignition temperature of the test item of 470°C.

A commercially available auto-ignition temperature apparatus was used for the determination of the degree of auto-ignitability of JNJ-118872-AAA (T000749).

The test item is determined to be auto-ignitable with an auto-ignition temperature of 470°C at 1025.5 – 1028.4 hPa.

Description of key information

Based on a GLP study (K1, Reingruber, 2017) based on the methods EC A.15, DIN Guide 51794 and IEC standard 79 -4, the test item is determined to be auto-ignitable with an auto-ignition temperature of 470°C at 1025.5 – 1028.4 hPa.
