Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Materials and methods

Test guideline
Qualifier:
according to guideline
Guideline:
other: Test Procedure VDI 2263, Part 1.
Principles of method if other than guideline:
The test was performed as stipulated in Test Procedure VDI 2263, Part 1, which is similar to UN Classification testing requirements. The sample in its delivery state and an inert reference sample are heated up to 370 °C at a rate of 0.5 K/min in an air flow of about 20 l/h. Subsequently, a fresh sample was heated at different ambient temperatures for a period of about at least five hours.
The temperature limit where only a negligible reaction was observed (delta T < 3 K) is called exothermic onset according to Grewer.
GLP compliance:
no
Remarks:
but in compliance with DIN EN ISO/IEC 17025

Test material

Details on test material:
Reactive Red F08 -0146

Results and discussion

Auto-ignition temperature (liquids / gases)
Auto-ignition temperature:
> 370 °C
Atm. press.:
101.325 kPa
Remarks on result:
other: Atmospheric pressure is assumed.
Relative self-ignition temperature (solids)
Relative self-ignition temperature:
> 370 °C
Remarks on result:
other: Atmospheric pressure is assumed.
Remarks:
at atm. press. of 101.325 kPa

Any other information on results incl. tables

The exothermic reaction according to Grewer started at 221 °C (see graphs attached below).

Comment: The temperature determined in this way depends upon the test method. Therefore it only serves as a rough estimate and for

comparison purposes. It cannot be used in all cases as the basis for the establishment of safe operating conditions. Self-heating

by oxidation depends on the sample size and the duration of the temperature exposure. Therefore, an increased sample volume

will considerably lower the ignition temperature.

Applicant's summary and conclusion

Conclusions:
The substance is not deemed to pose a self ignition hazard.
Executive summary:

The test was performed as stipulated in Test Procedure VDI 2263, Part 1, which is similar to UN Classification testing requirements. The sample in its delivery state and an inert reference sample are heated up to 370 °C at a rate of 0.5 K/min in an air flow of about 20 l/h. Subsequently, a fresh sample was heated at different ambient temperatures for a period of about at least five hours. 

The temperature limit where only a negligible reaction was observed (delta T < 3 K) is called exothermic onset according to Grewer. An exothermic reaction starting from 221 °C was observed, however this was considered to be minimal. The substance is not considered to pose a hazard by auto-ignition.
