Materials and methods

Test guideline
Qualifier:
no guideline followed
Principles of method if other than guideline:
No guideline is specified in the report, which refers to an older study. Data was taken from an older study (CPHE: SD2002/01462/00). In this memo the Max. Recommended Processing Temperature was set at 42°C based on 100°C rule. Re-interpreting data using the TMR AD24 approach results in a value of 50°C (to the nearest 10°C). This is used in this study.
GLP compliance:

Applicant's summary and conclusion

Conclusions:
This material may be self-reactive. Over-heating could result in a thermal explosion.
Further assessment of thermal hazards is required if the proposed processing or drying temperature is above 50°C.
