- Endpoint:
- relative self-ignition temperature (solids)
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- From 17 July to 8 August, 2017
- 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:
- other: Recommendations on the Transport of dangerous goods: Manual of Tests and Criteria, 6th edition, New York and Geneva, 2015: Appendix 6 Screening Procedures, Division 4.2: Substances which may be liable to spontaneous combustion
- Qualifier:
- according to guideline
- Guideline:
- other: VDI 2263 Sheet 1 Grewer Oven
- Version / remarks:
- adopted in 1990
- GLP compliance:
- yes (incl. QA statement)
- Relative self-ignition temperature:
- 240 - 290 °C
- Remarks on result:
- preliminary test
- Conclusions:
- Non-self-heating
- Executive summary:
The self-ignition behavior of the product is determined in the Grewer Oven according to VDI 2263, sheet 1 and with respect to the classification procedures of both the UN Transport Regulation (Class 4, Division 4.2) and GHS as specified in EC 1272/2008 (CLP Regulation, Annex 1: 2.11), respectively. The Grewer Oven test can be used as screening test for the classification as self-heating substance “Substances liable to spontaneous combustion” (UN Transport Regulation) and EC 1272/2008 (CLP Regulation). For this purpose, a safety margin of 80 K above the reference temperature for a sample volume of 1 l in the UN Test N.4 has to be applied.
Starting at a temperature of approx. 240 °C the test item showed a slight self-heating, which leaded to a maximum temperature of 290 °C. After the measurement a black residue remained in the basket.
For the test item in mixture with Kieselguhr no endothermic or exothermic effects were detected.
Conclusion
Non-self-heating

Description of key information
Non-self-heating
Key value for chemical safety assessment
Additional information
According to the CLP Regulation (EC) No 1272/2008, 2.11 section, a self-heating substance or mixture is a liquid or solid substance or mixture, other than a pyrophoric liquid or solid, which, by reaction with air and without energy supply, is liable to self-heat.
The classification procedure for self-heating substances or mixtures need not be applied if the results of a screening test can be adequately correlated with the classification test and an appropriate safety margin is applied. An example of screening test is the Grewer Oven test (VDI guideline 2263, Part 1, 1990, Test methods for the Determination of the Safety Characteristics of Dusts) with an onset temperature 80 K above the reference temperature for a volume of 1 l.
On the basis of the Grewer Oven test results, taken into consideration the safety margin above mentioned, the substance does not meet the criteria to be classified as self-heating substance either in class 4, division 4.2 according to the UN Transport Regulation, neither in accordance to the CLP Regulation (EC) No 1272/2008.
