- Guideline:
- other: UN test N.4 for self-heating substances
- Version / remarks:
- UN "Recommendations on the Transport of Dangerous Goods: Manual of Tests and Criteria", 6th revised edition 2015
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Key result
- Remarks on result:
- no self ignition observed under the test conditions
- Remarks:
- Using a 10 cm sample cube at 140 °C oven temperature, no self ignition was observed.
- Conclusions:
- UN test N.4 for self-heating substances: no classification requirements with regard to self-heating properties
- Executive summary:
To check for classification requirements regarding self-heating properties, the submission substance was assessed compliant with GLP in a reliable and valid study: the study was performed according to UN test N.4, described in division 4.2 (self-heating substances) of the “Recommendations on the Transport of Dangerous Goods: Manual of Tests and Criteria”, 6th revised edition 2015.
Due to the fact that a negative result was obtained in the test using a 10 cm sample cube at 140 °C, the test item had not to be classified in division 4.2 (self-heating substances) in the sense of UN Manual of Test and Criteria, Method N.4.
Due to the fact that a negative result was obtained in the test using a 10 cm sample cube at 140 °C the test item had not to be classified as “self-heating substance” according to chapter 2.11 [1] of the GHS (CLP) regulations.

Reference
Individual results
For the test in the 10 cm cube at an oven temperature of 140 °C ± 2 °C an amount of 701.32 g of the test item was filled in the sample container. The test item temperature reached the oven temperature (140 °C) after approximately 5 hours and continued to rise as a consequence of an exothermal effect up to 142 °C. Due to the small temperature rise self-ignition was not observed and the test result was therefore negative.The diagram (see attached illustration) shows the temperature / time curves for this test.
After the measurement the mesh wire basket contained approximately 6 wt.% less test item than at the start. The remaining test item was discoloured to dark brown and expanded.
Due to the negative result at 140 °C (10 cm cube) the test item had not to be classified as “self-heating substance” in the sense of UN Manual of Tests and Criteria, Method N.4, and had not to be classified as “self-heating substance” according to chapter 2.11[1] of the GHS (CLP) regulations.

Description of key information
UN test N.4 for self-heating substances: no classification requirements with regard to self-heating properties - no self-ignition was observed.
Key value for chemical safety assessment
