Materials and methods

Test guideline

Qualifier:

no guideline followed

Principles of method if other than guideline:

The decomposition energy is measured by a differential scanning calorimetry.
A quantity of sample is sealed in a test crucible. This is placed in a furnace cell along with an empty reference pan. The furnace is allowed to equilibrate to the starting temperature and both pans are then heated at between 0.5 and 20 K/min until the final temperature is reached. The temperature of the sample and that of the reference pan are monitored. Any exothermic activity within the sample will result in a larger heat flow out of the cell relative to the reference pan.The peak height or area under the curve indicating the magnitude of the energetic activity.

GLP compliance:

no

Results and discussion

Results:

As the decomposition energy is lower than 300 J.g-1, the sample should not be classified as auto reactive material.

Any other information on results incl. tables

The full profile of the experiment is provided in Illustration.

The sample was observed to undergo an exothermic event from 151.5°C which had a heat of decomposition of -24.1 J.g^-1. An endothermic event was then observed to commence from 299.3°C (77.2 J.g^-1). No further significant energetic events were noted up to 500°C.

As the decomposition energy is lower than 300 J.g-1, the sample should not be classified as auto reactive material.

Applicant's summary and conclusion

Conclusions:

As the decomposition energy is lower than 300 J.g-1, the sample should not be classified as auto reactive material.
