Applicant's summary and conclusion
- Conclusions:
- The autoignition temperature of CAS# 756-12-7 is 520 °C.
- Executive summary:
The autoignition temperature of CAS# 756-12-7 was measured according to 92/69/EEC, A.15, DIN 51794, and IEC 79-4. The lowest observed autoignition temperature at 101.33 - 101.98 kPa was 523 °C. This temperature was rounded down to the nearest 5 °C to obtain the autoignition temperature according to guideline. The autoignition temperature of CAS# 756-12-7 is 520 °C.
The test was conducted according to internationally accepted guidelines and under GLP criteria. It is reliable without restriction.
