Link to relevant study record(s)

Reference

Endpoint:

relative self-ignition temperature (solids)

Type of information:

experimental study

Adequacy of study:

key study

Study period:

2018

Reliability:

2 (reliable with restrictions)

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: Laboratory (blowpipe)

GLP compliance:

no

Other quality assurance:

other: ISO 9001-2008

Key result

Relative self-ignition temperature:

> 650 °C

Remarks on result:

no self ignition observed under the test conditions

A black residue remained in the crucible after the process and no reaction was observed during that treatment. No combustion nor violent reaction were seen.

Conclusions:

It can be excluded that the test item has self-ignition properties.

Description of key information

Based on the observations of an experiment, where the sample has been heated up to 650ºC, it is concluded that the test item has not self-ignition properties.

Key value for chemical safety assessment

Autoflammability / Self-ignition temperature at 101 325 Pa:

650 °C
