Auto flammability

Link to relevant study record(s)

Reference

Endpoint:

auto-flammability

Type of information:

experimental study

Adequacy of study:

key study

Study period:

January 2012

Reliability:

2 (reliable with restrictions)

Rationale for reliability incl. deficiencies:

comparable to guideline study with acceptable restrictions

Remarks:

This study was considered as reliable with restrictions because it was not conducted under GLP and there are some lack of details in the study report.

Reason / purpose for cross-reference:

Key result

Auto-ignition temperature:

250 °C

Atm. press.:

994 hPa

Remarks on result:

other: Time lag: 4 minutes

Preliminary study:

Time lag: 4 minutes ; amount 5 drops = 3 mL

Temperature	Results
240°C	No-ignition
260°C	Ignition

The preliminary results indicate that the auto-ignition temperature is aroud 260°C at 994 hPa.

Main study:

Time lag: 4 minutes ; amount of test item: 1 to 5 droplets = 0.6 to 3 mL

Temperature	exp 1	exp 2	exp 3	exp 4	exp 5
240°C	No ignition	No ignition	No ignition	No ignition	No ignition
250°C	No ignition	No ignition	No ignition	Ignition	-
260°C	Ignition	-	-	-	-

During the main test the auto-ignition temperature of nerol was determined to be 250°C at 994 hPa.

Conclusions:

The auto ignition temperature of nerol was determined to be 250 °C at 994 hPa.

Executive summary:

The determination of the auto flammability was performed in accordance with regulation (EC) No 440/2008 method A.15 "Auto-Ignition Temperature (Liquids and Gases)" (May 2008) and the Standard Test Method DIN 51794.

In the preliminary test, ignition was observed at around 260 °C at 994 hPa.

In the main test, the auto ignition temperature of nerol was determined to be 250 °C at 994 hPa.

 

Description of key information

The auto ignition temperature of nerol is 250 °C at 994 hPa.

Key value for chemical safety assessment

Autoflammability / Self-ignition temperature at 101 325 Pa:

250 °C

Additional information

Key study conducted according to EU A.15 guideline and DIN 51794 method. The result is scientifically acceptable but not obtained under GLP. Therefore a reliability of 2 (reliable with restrictions) was assigned.
