1 (reliable without restriction)

Rationale for reliability incl. deficiencies:

guideline 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:

> 320 °C

Remarks on result:

other: no autoflammability observed

Remarks:

at atm. press. of ca.1013.0 hPa

The test substance was tested by EU method A16. Aself-heating was observed from 230°C, which led since a self-warming to 317° C. No spontaneous combustion was observed using this tesing metod.

Conclusions:

No spontaneous combustion observed

Executive summary:

The test substance Reactive-Orange F-64258 FW tested by EU method A16. Aself-heating was observed from 230°C onwards, which led to a self-warming to 317° C. No spontaneous combustion according to test method A16 was observed.

Description of key information

No self-ignition was observed

Key value for chemical safety assessment

Autoflammability / Self-ignition temperature at 101 325 Pa:

320 °C

Additional information
