- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 06 Feb 2017 - 27 Feb 2017
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Reason / purpose for cross-reference:
- reference to same study
- Qualifier:
- according to guideline
- Guideline:

- Principles of method if other than guideline:
- The cubic sample containers of 25 mm and 100 mm side lengths are employed. They are open at the top and manufactured from stainless-steel net, with a mesh opening of 0.053 mm. Each container is housed in an outer cubic container cover, manufactured from stainless-steel net with a mesh opening of 0.595 mm which is slightly larger than the sample container, so that the container fits in this cover. In order to minimise the effects of air circulation, another stainless-steel cage, manufactured with a mesh opening of 0.595 and 150 x 150 x 250 mm in size, houses both these baskets.
The test material, in its commercial form, is filled to the brim of the sample basket which is then tapped several times. If the sample has been seen to settle then more material is added. The container is housed in the covers and placed in the centre of the oven at the required test temperature.
A hot air, circulating type oven with an inner capacity of approximately 120 litres and capable of controlling the internal temperature at 140 ± 2 °C is utilised. In the initial test (with a 100 mm cube), the oven temperature is raised to 140 °C and held isothermally for a test period of 24 hours. The temperature of the sample and oven are continually monitored / recorded with inconel sheathed thermocouples to provide accurate temperature measurement. One thermocouple is placed in the centre of the sample and the other between the sample container and the oven wall - GLP compliance:
- not specified
- Specific details on test material used for the study:
- As received, the sample is observed to be a black powder. In order to obtain sufficient sample quantity of finer particle size, it was necessary to mechanically mill the material.
Moisture content 7.90 % by weight - Key result
- Relative self-ignition temperature:
- > 140 °C
- Remarks on result:
- no self ignition observed under the test conditions
- Remarks:
- On completion of testing, the sample remained unchanged
- Conclusions:
- No self ignition was observed for the test item graphene under the test conditions, indicating a relative self-ignition temperature > 140°C.
- Executive summary:
Auto-ignition temperature of the test item was assessed according to UN Transportation of Dangerous Goods Recommendations, Test N.4. No self ignition was observed for the test item graphene under the test conditions, indicating a relative self-ignition temperature > 140°C.
