Reference

Endpoint:

relative self-ignition temperature (solids)

Type of information:

experimental study

Adequacy of study:

key study

Study period:

01 September 2017 - 13 September 2017

Reliability:

1 (reliable without restriction)

Rationale for reliability incl. deficiencies:

guideline study

Remarks:

Test method according to EEC method A.16. GLP study.

Qualifier:

according to guideline

Guideline:

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

Deviations:

no

GLP compliance:

yes (incl. QA statement)

Key result

Relative self-ignition temperature:

391 °C

At the oven temperature of 157 °C there is a rapid rise in temperature in the sample but sample temperature only reaches a maximum temperature 317 °C. At the oven temperature of 391 °C, the sample temperature reaches 400 °C. According to the criteria of the method A.16 the observed phenomenon indicates that the relative self-ignition temperature of the sample is 391 °C. See image attached.

Conclusions:

The relative self-ignition temperature of the tested material is 391ºC according to EU method A.16 criteria.

Executive summary:

The determination of the self-ignition temperature of the tested material was performed according to EU Method A.16 (GLP study). A cube of stainless steel wire mesh was filled with the test item, suspended in the centre of the laboratory oven and heated at a constant rate of 0.5ºC/min until reaching 400ºC. One thermocouple was placed at the centre of the cube and the other between the cube and the oven wall to record the oven temperature. Based on the test method, the temperature of the oven at which the sample temperature reaches 400 °C is the self-ignition temperature. According to the results, the relative self-ignition temperature of the tested material is 391ºC.
