Reference

Endpoint:

relative self-ignition temperature (solids)

Type of information:

experimental study

Adequacy of study:

key study

Study period:

28 Nov 2014

Reliability:

2 (reliable with restrictions)

Rationale for reliability incl. deficiencies:

guideline study with acceptable restrictions

Reason / purpose for cross-reference:

reference to same study

Qualifier:

according to guideline

Guideline:

other: VDI 2263 (Grewer oven test)

Deviations:

yes

Remarks:

Grewer oven test was performed as a preliminary test to the UN Test N.4, which was not done. Atmospheric pressure was not reported.

GLP compliance:

yes

Remarks:

The Department of Health of the Government of the United Kingdom

Remarks on result:

no self ignition observed under the test conditions

Remarks:

at atm. press. of ca.1013.0 hPa

Atmospheric pressure was not reported (assumed to be ca. 1013 hPa).

On completion of testing a crusty black/brown material remained.

Exothermic activity observed during the test: yes

Time when sample temperature exceeded reference temperature: 140.5 min

Oven temperature when sample temperature exceeded reference temperature: 307 °C

The substance could be excluded from classification as a self-heating solid of UN Class 4.2 as the onset temperature in the screening test exceeded 220 °C. The UN N.4 test was not performed.

Description of key information

no self-ignition
onset temperature 307 °C at ca. 1013 hPa (VDI 2263, preliminary to UN N.4)

Additional information

The reported temperature is the Grewer oven temperature when sample temperature exceeded reference temperature. The substance could be excluded from classification as a self-heating solid of UN Class 4.2 as the onset temperature in the screening test exceeded 220 °C.
