Results and discussion

Relative self-ignition temperature (solids)

Key result

Relative self-ignition temperature:

240 °C

Any other information on results incl. tables

The temperatures of the oven and the sample were printed every 5 minutes while the temperature of the oven was increased to 400 °C with a nominal heating rate of 0.5 K/min. An ignition of the test item would have been detected automatically.

Applicant's summary and conclusion

Conclusions:

The temperature of the test substance had reached 400°C according to EU-Method A.16 at the oven temperature of 245.0 °C.

Therefore, the test substance Glutardialdehyde bis-Sodiumbisulfite is considered as autoflammable under the test conditions with a Relative Self Ignition Temperature of 240.0 °C
