Auto flammability

Link to relevant study record(s)

Reference

Reference 1

Endpoint:

auto-flammability

Type of information:

read-across based on grouping of substances (category approach)

Adequacy of study:

supporting study

Study period:

1996

Reliability:

2 (reliable with restrictions)

Rationale for reliability incl. deficiencies:

other: Although not GLP, there is no reason to doubt the results obtained from these straight forward and routinely used tests. Furthermore, results are completely in line with general available information.

Justification for type of information:

Refer to the Quaternary ammonium salts (QAS) category or section 13 of IUCLID for details on the category justification.

Qualifier:

according to guideline

Guideline:

EU Method A.15 (Auto-Ignition Temperature (Liquids and Gases))

Version / remarks:

Cited as Directive 92/69/EEC, A.15

GLP compliance:

no

Key result

Auto-ignition temperature:

371 °C

Remarks on result:

other: atm. press.: not specified

Conclusions:

Under the study conditions, an autoignition temperature of 50% aqueous solution of the read across substance was found to be 371°C.

Executive summary:

A study was conducted to determine the autoignition temperature of the read across substance, C12-16 ADBAC (50% active in water) according to EU Method A.15. The autoignition temperature apparatus DIN 51794 was used in this experiment. Under the study conditions, an autoignition temperature of 50% aqueous solution of the read across substance was found to be 371°C (Schuurman, 1996). Based on the results of the read across, a similar autoiginition temperature is expected for the test substance.

Endpoint:

relative self-ignition temperature (solids)

Type of information:

read-across based on grouping of substances (category approach)

Adequacy of study:

key study

Study period:

From February 16, 2007 to February 21, 2007

Reliability:

2 (reliable with restrictions)

Rationale for reliability incl. deficiencies:

guideline study

Remarks:

KL2 due to RA

Justification for type of information:

Refer to the Quaternary ammonium salts (QAS) category or section 13 of IUCLID for details on the category justification.

Qualifier:

according to guideline

Guideline:

EU Method A.16 (Relative Self-Ignition Temperature for Solids)

Version / remarks:

Cited as Directive 92/69/EEC, A.16

Deviations:

no

GLP compliance:

yes (incl. QA statement)

Key result

Relative self-ignition temperature:

> 403 °C

Remarks on result:

no self ignition observed under the test conditions

No autoignition temperature was observed up to the maximum test temperature of 403°C.

Conclusions:

Under the study conditions, no autoignition temperature was observed for the read across substance up to the maximum test temperature of 403°C.

Executive summary:

A study was conducted to determine the autoignition of the read across substance, C12-16 ADBAC (94.4% active) according to EU Method A.16, in compliance with GLP. Height 8 cm3 (3.8 g) of the read across substance was placed in an oven at 24°C; the temperature time curve relating to conditions in the center of the sample was recorded while the temperature of the oven was increased to 400°C at a rate of 0.5°C/min. The temperature of the oven at which the sample temperature reaches 400°C by self-heating is called the autoignition temperature for the purpose of this test. Under the study conditions, no autoignition temperature was observed for the read across substance up to the maximum test temperature of 403°C (Moller, 2007). Based on the results of the read across, a similar autoiginition temperature is expected for the test substance.

Description of key information

The autoignition temperature was determined based on a study conducted with read across substance, C12 -16 ADBAC according to EU Method A.16 and 15 (Moller, 2007 and Schuurman, 1996) 

Additional information

Pure substance: No auto-ignition was observed up to the maximum test temperature of 403°C (Moller, 2007); 50% aqueous solution: 371°C (Schuurman, 1996)
