Auto flammability

Link to relevant study record(s)

Reference

Endpoint:

auto-ignition temperature (liquids)

Type of information:

experimental study

Adequacy of study:

key study

Study period:

11-17 November 2015

Reliability:

1 (reliable without restriction)

Rationale for reliability incl. deficiencies:

guideline study

Remarks:

The study was conducted according to an internationally recognised method, and under GLP. No deviation was reported. Test substance is adequately specified with purity. Therefore full validation applies.

Qualifier:

according to guideline

Guideline:

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

Deviations:

no

Qualifier:

according to guideline

Guideline:

other: DIN 51794 (2003): Determination of ignition temperature

Principles of method if other than guideline:

Not applicable

GLP compliance:

yes (incl. QA statement)

Remarks:

inspected on January 22 and 23, 2013 / signed on March 22, 2013

Specific details on test material used for the study:

Storage condition of test material: 11-25 °C, dry, keep container closed

Key result

Auto-ignition temperature:

235 °C

Atm. press.:

999.4 - 1 014.2 hPa

Preliminary Test

 

Table 4.12/1: Results of the preliminary test

 

Temperature (°C)	244	266	291	291
Ignition (+/-)	-	-	-	+

In the preliminary test, an ignition was observed at 291°C(Atmospheric pressure: 1014.2 hPa)

 

Main test

Table 4.12/2: Lowest temperatures at which an ignition occurred

Main test series	Lowest temperatures of an ignition	Highest temperatures without an ignition	Atmospheric pressure
1	242 °C	241 °C	1014.2 hPa
2	238 °C	237 °C	1014.2 hPa
3	236 °C	234 °C	999.4 hPa

*only the measurements after the lowest temperature of ignition are considered as relevant for evaluation.

Based on results of the main test series, the lowest auto-ignition temperature was 236 °C. Results are within the required range of 10 °C, therefore the validity criterion is fulfilled.

The auto-ignition temperature rounded down to the nearest multiple of 5 °C was determined as 235 °C.

Conclusions:

This parameter/method is not relevant for classification, however the information is useful regarding potential additional fire hazard. No particular hazard is anticipated in normal conditions of storage.

Executive summary:

The substance was tested for its autoflammable properties, according to Standard DIN 51794 (listed in EU A.15 guideline). Test material was injected into a heated flask, until the lowest temperature at which ignition occurs was determined.

The auto-ignition temperature of the test substance has been determined to be 235 °C at 999.4-1014.2 hPa.

Description of key information

No particular hazard is anticipated in normal conditions of storage. 

Key value for chemical safety assessment

Autoflammability / Self-ignition temperature at 101 325 Pa:

235 °C

Additional information

A fully reliable experimental study, conducted according to a recognized DIN/EU method under GLP, is available. Therefore, it is considered as a key study. The result is retained as key data.

This parameter is not relevant for classification, however the information is useful regarding process safety and potential additional fire hazard
