- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- test procedure in accordance with national standard methods
- Qualifier:
- according to guideline
- Guideline:
- other: Guideline VD!2263, sheet 1 (Grewer-oven)
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- other: UN Recommendations on the Transport of Dangerous Goods, 6th revised edition, 2015, Appendix 6
- Deviations:

- Specific details on test material used for the study:
- - Batch No.: 2019002
- Purity: 98.39 %
- Physical state: White solid
- Storage conditions: Ambient temperature (10–30 °C)
- Expiry date: 2020-10-21 - Key result
- Relative self-ignition temperature:
- > 460 °C
- Remarks on result:
- no self ignition observed under the test conditions
- Conclusions:
- In a study conducted according to the guideline VDI 2263, sheet 1 (Grewer-Oven), no self-ignition temperature was observed up to 460 °C.
- Executive summary:
A GLP study conducted according to the guideline VDI 2263, sheet 1 (Grewer-Oven), showed that no self-ignition temperature was observed up to 460 °C (final oven temperature). Due to these results the test item does not have to be classified as as self-heating substance, class 4.2 of the Recommendations on the Transport of Dangerous Goods / Manual of Tests and Criteria and according to chapter 2.11 of the CLP Regulation 1272/2008.
Reference
1.9 g of the test item were placed into the wire-basket. The temperature of the test item followed behind the oven temperature starting at an oven temperature of approx. 30 °C. ln the temperature range of 200 to 240 °C an endothermal effect was observed. No exothermal effect was observed until the maximum temperate of the measurement (460 °C). After the test the basket was empty. As no exothermal process was observed further testing was not necessary.
Description of key information
N-(4-((4-(3-phenylureido)phenyl)sulfonyl)phenyl)benzenesulfonamide shows no self-ignition within the relevant temperature range (≤ 460 °C).
Key value for chemical safety assessment
