Administrative data
- Endpoint:
- appearance / physical state / colour
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 2012-07-23 - 2013-01-10
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Remarks:
- Also conducted according to GLP.
Cross-reference
- Reason / purpose for cross-reference:
- reference to same study
Reference
- Endpoint:
- relative self-ignition temperature (solids)
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 2012-07-23 - 2013-01-10
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Remarks:
- Study conducted in compliance with international standard guidelines under GLP conditions. The study report was well documented with all mandatory information included.
- Reason / purpose for cross-reference:
- reference to same study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.16 (Relative Self-Ignition Temperature for Solids)
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Remarks:
- 2012-09-07
- Remarks on result:
- no self-ignition observed up to the melting point
- Remarks:
- The test item melts at 219-239°C. No relevant exothermic reaction/self-heating of the sample was observed up to that temperature.
- Conclusions:
- No relevant exothermic reaction/self-heating of the sample was observed
- Executive summary:
The determination of self ignition temperature was performed according to Method A.15 of Commission Regulation (EC)N°440/2008 of 30 May 2008 and GLP. No deviation of the guidelines was observed during the test.
The test item is heated in a fine mesh stainless steel cube that is suspended in an oven. The temperature/time-curves of both test item and oven are recorded.The self-ignition temperature, as obtained by this method, is the minimum ambient temperature expressed in (°C) at which a certain volume of a substance ignites under defined conditions.The temperature of the oven at which the sample reaches 400°C by self-heating is stated as the self-iginition temperature of the test item.
The test item has been determined not to have a relative self-ignition temperature below its melting temperature. The test item melted at 219-239°C.
The test item was a white crystalline solid. Whilst heating the test item, no relevant exothermic reaction/self-heating of the sample had been observed. On completion of the test, the cube contained a hard fused white solid.
The melting temperature of the test item is stated as 219 to 239°C. This was observed in the differences between the sample and reference curve at approximately 200°C. As the oven temperature was increased to 250°C, the test item was heated to above its melting point.
