Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Reference
Endpoint:
relative self-ignition temperature (solids)
Type of information:
experimental study
Adequacy of study:
key study
Study period:
23 February 2017-06 June 2017
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Justification for type of information:
The study was conducted according to an internationally recognised method, and under GLP. No deviation was reported. Test substance is adequately specified with purity. Therefore full validation applies.
Qualifier:
according to guideline
Guideline:
EU Method A.16 (Relative Self-Ignition Temperature for Solids)
Deviations:
no
GLP compliance:
yes (incl. QA statement)
Remarks:
UK GLP compliance programme (inspected on 05 July 2016 / signed on 28 Octobre 2016)
Key result
Remarks on result:
other: The test item has been determined not to have a relative self-ignition temperature before decomposing with softening/melting.

Results

The test item was a fine white powder before testing. Whilst heating the test item, no relevant exothermic reaction was observed.

On completion of the test, no test item remained in the mesh cube; however, a puddle of test item residue was observed on the base of the oven.

The test item has been determined not to have a relative self-ignition temperature before decomposing with softening/melting.

Please see the graft temperature vs time grafh in the experimental report for further information.

Conclusions:
The test item has been determined not to have a relative self-ignition temperature before decomposing with softening/melting.
Executive summary:

The test substance was tested for its relative self ignition properties following Method A16 (GLP).

The test item was a fine white powder before testing. Whilst heating the test item, no relevant exothermic reaction was observed. On completion of the test, no test item remained in the mesh cube; however, a puddle of test item residue was observed on the base of the oven. The test item has been determined not to have a relative self-ignition temperature before decomposing with softening/melting.

Description of key information
