Reference

Endpoint:

relative self-ignition temperature (solids)

Type of information:

experimental study

Adequacy of study:

key study

Study period:

Between 06 March and 13 March 2012

Reliability:

1 (reliable without restriction)

Rationale for reliability incl. deficiencies:

guideline study

Remarks:

Study conducted in compliance with agreed protocols, with no or minor deviations from standard test guidelines and/or minor methodological deficiencies, which do not affect the quality of the relevant results. The study report was conclusive, done to a valid guideline and the study was conducted under GLP conditions.

Qualifier:

according to guideline

Guideline:

EU Method A.16 (Relative Self-Ignition Temperature for Solids)

Deviations:

no

GLP compliance:

yes (incl. QA statement)

Specific details on test material used for the study:

White solid, batch# 9311205/008, purity 93%

Remarks on result:

no self-ignition observed up to the melting point

Remarks:

The test item has been determined not to have a relative self-ignition temperature below its melting temperature.

Results

The test item was a white solid. Whilst heating the test item, no thermal events of any significance were registered on the temperature curve (shown in Attachment 1 of this summary). On completion of the test, the cube contained a white solid with a paste like consistency.

Conclusions:

The test item has been determined not to have a relative self-ignition temperature below its melting temperature.

Executive summary:

Testing was conducted using a procedure designed to be compatible with Method A16 Relative Self-Ignition Temperature for Solids of Commission Regulation (EC) No 440/2008 of 30 May 2008.

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 cube was completely filled with the test item and placed in the center of the oven at room temperature. A thermocouple was placed in the center of the sample and another in the oven. The oven temperature was programmed to increase from ambient to 105 °C at a rate of 0.5 °C/min. The temperature curves relating to the condition in the center of the sample and the oven were recorded on a data logger. The appearance of the test item was recorded before and after the test.

Conclusion

The test item has been determined not to have a relative self-ignition temperature below its melting temperature.
