Type of information:

experimental study

Adequacy of study:

key study

Study period:

January 24, 2012 - March 19, 2012

Reliability:

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)

Version / remarks:

(2008)

Deviations:

no

GLP compliance:

yes

Key result

Remarks on result:

other: As no exothermic effect of the test substance was observed, the substance is considered not self-ignitable.

After the experiment, the test substance had turned into a charred residue and part of the test substance was collected in a container that was placed below the cube. It is unclear whether this was caused by melting or expanding of the test substance.

Conclusions:

In accordance with EU Method A.16 (2008) and according to GLP principles the self-ignition temperature of the substance was determined using a temperature programmed laboratory oven, a stainless steel wire mesh cube, NiCr/NiAl thermocouples and a temperature recording device. As no exothermic effect of the test substance was observed, the substance is considered not self-ignitable.

Adequacy of study:

key study

Reason / purpose for cross-reference:

read-across source

Key result

Auto-ignition temperature:

470 °C

Atm. press.:

>= 1 005.9 - <= 1 030.6 hPa

Remarks on result:

other: Auto-ignition temperature of an aqueous solution (with a solid content of approximately 39%)

Conclusions:

A commercially available auto-ignition temperature apparatus was used for the determination of the degree of auto-ignitability of an aqueous solution of the source chemical amphoacetates C12, a member of the chemical category, according to EC, DIN and IEC guidelines and according to GLP principles. The aqueous solution is auto-ignitable with an auto-ignition temperature of 470°C at atmospheric pressures between 1005.9 and 1030.6 hPa. This result is read-across to the registered substance.

Description of key information

The substance is not self-ignitable. Based on a study conducted with a substance analogue (amphoacetates C12), aqueous solutions of the substance are auto-ignitable with an auto-ignition temperature of approximately 470°C.

Key value for chemical safety assessment
