- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- october 2009
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Remarks:
- Study performed according to international guideline. No deficiencies. Performed under internal quality management system.
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.14 (Explosive properties)
- Version / remarks:
- Official Journal of the European Union no. L142, May 31, 2008
- Deviations:
- yes
- Remarks:
- No full study is necessary
- Qualifier:
- according to guideline
- Guideline:
- other: ASTM E537-07 October 1, 2007
- Deviations:
- no
- Principles of method if other than guideline:
- A screening test was conducted to determine the decomposition energy of the substance by thermal analysis (Differential Scanning Calorimetry, DSC).
Finally, a full study is considered as not necessary, because:
According to EC Regulation 1272/2008 (CLP), Annex I, Part 2, paragraph 2.1.4.2 & 2.1.4.3, a substance or mixture shall not be classified as explosive if the exothermic decomposition energy is less than 500 J/g and the onset of exothermic decomposition is below 500°C. - GLP compliance:
- no
- Parameter:
- sensitiveness to impact: impact energy (J)
- Remarks on result:
- not measured/tested
- Remarks:
- exothermic decomposition energy < 500 J/g
- Parameter:
- sensitiveness to friction: friction load (N)
- Remarks on result:
- not measured/tested
- Remarks:
- exothermic decomposition energy < 500 J/g
- Parameter:
- thermal sensitivity - Koenen test: limiting diameter (mm)
- Remarks on result:
- not measured/tested
- Remarks:
- exothermic decomposition energy < 500 J/g
- Key result
- Parameter:
- other: DSC Screening test
- Remarks on result:
- negative (not further specified)
- Remarks:
- exothermic decomposition energy < 500 J/g
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- 3811-04-9, KClO3
Based on results in this report, the decomposition energy of test item measured using the DSC screening test is < 500 J/g (i.e. 449 J/g), which means that the substance can be designated as non-explosive and that further testing on explosive properties according to EC Regulation No 440/2008, Guideline A.14 or Part I of the UN RTDG, Manual of Tests and Criteria is not required.
Reference
The DSC curve shows a sharp endothermic melting peak, followed by two exothermic decomposition peaks. The decomposition energy of the two exothermal peaks together is 449 J/g (1st peak 239 J/g, 2nd peak 210 J/g)..
The total exothermic decomposition heat is < 500 J/g. This means that the substance can be designated as non-explosive according to European Chemicals Agency (ECHA), Guidance on information requirements and chemical safety assessment, Chapter R.7a, Endpoint specific guidance, May 2008, and according to EC Regulation No 1271/2008 (CLP), Annex I, Part 2, paragraph 2.1.4.2 and 2.1.4.3. It also means that further testing on explosive properties according to EC Regulation No 440/2008, Guideline A.14 or Part I of the UN RTDG, Manual of Tests and Criteria is not required.
Description of key information
3811-04-9, KClO3
The decomposition energy is < 500 J/g (i.e. 449 J/g), which means that the substance can be designated as non-explosive and that further testing on explosive properties according to EC Regulation No 440/2008, Guideline A.14 or Part I of the UN RTDG, Manual of Tests and Criteriai is not required.
Key value for chemical safety assessment
- Explosiveness:
- non explosive
Additional information
Potassium chlorate is non explosive
Justification for classification or non-classification
According to EC Regulation 1272/2008 (CLP), Annex I, Part 2, paragraph 2.1.4.2 & 2.1.4.3, a substance or mixture shall not be classified as explosive if the exothermic decomposition energy is less than 500 J/g and the onset of exothermic decomposition is below 500°C.
Based on the information indicated above, no classification is needed on explosivity.
