Applicant's summary and conclusion

Conclusions:
In conclusion, ucb 22060 is not auto-flammable, according to the criteria as described in the guideline.
Executive summary:

The determination of the relative self-ignition temperature of the test item was performed according to the EEC Directive 92/69, Part A, Methods for the determination of physiochemical properties, A. 16 “Relative self-ignition temperature for solids”, EEC Publication No. L383, December 1992. The correlation between the temperature of the oven and the sample temperature of ucb 22060 is shown in the figure below. Using a linear increase in temperature of about 0.5°C/min, ucb 22060 showed no exothermic reaction. ucb 22060 has a melting point at about 108°C (see RCC study 849448). As the above mentioned guideline only applies to solids, the temperature range between 108°C and 400”C is not relevant for the present test item. At the end of the measurement ucb 22060 had run out of the sample cube due to melting and was coloured black. In conclusion, ucb 22060 is not guideline. auto-flammable, according to the criteria as described in the
