Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
study well documented, meets generally accepted scientific principles, acceptable for assessment
Qualifier:
equivalent or similar to
Guideline:
EU Method A.16 (Relative Self-Ignition Temperature for Solids)
GLP compliance:
not specified
Key result
Relative self-ignition temperature:
> 1 100 °C
Remarks on result:
no self ignition observed under the test conditions
Conclusions:
Heating RESHS to 1100 °C in air shows no exothermic reactions. We can therefore conclude that this material does not present any auto-ignition risks in air up to 1100°C. A large amount of water is present: more than 55 wt%. The dry samples decompose at about 800 °C.
Executive summary:

TGA/DSC measurements were performed on RESHS. The measurement are made on the Netzsch STA 409 PC. In a constant airflow, the temperature is increased at a rate of 5 °C/min, up to a temperature of 1100 °C. The software Proteus is used to construe the raw data.

Heating RESHS 316 REACH to 1100 °C in air shows no exothermic reactions. We can therefore conclude that this material does not present any auto-ignition risks in air up to 1100°C.
