Endpoint:

relative self-ignition temperature (solids)

Type of information:

experimental study

Adequacy of study:

key study

Study period:

April from 18th to 26th, 2018

Reliability:

1 (reliable without restriction)

Rationale for reliability incl. deficiencies:

test procedure in accordance with generally accepted scientific standards and described in sufficient detail

Qualifier:

according to guideline

Guideline:

EU Method A.16 (Relative Self-Ignition Temperature for Solids)

Deviations:

no

GLP compliance:

yes (incl. QA statement)

Specific details on test material used for the study:

The test item was used in its initial form.

Remarks on result:

no self ignition observed under the test conditions

Remarks:

(up to 400 °C)

Conclusions:

No self-ignition up to 400 °C.

Executive summary:

The relative self-ignition temperature of the test item was determined in accordance with the method described in the EU method A.16. A certain volume of the test item was placed into an oven at ambient temperature; the temperature/time curve was recorded while the temperature of the oven was increased up to 400 °C, at a rate of approximately 0.5 °C/min. Three replicate tests were performed.

In the course of the study, the test item did not self-ignite up to 400 °C. Thus, no self-ignition temperature could be stated.

Conclusion

No self-ignition up to 400 °C.

Description of key information
