Key result

Remarks on result:

other: No relative self-ignition was recorded as no ignition occurred up to the complete removal of the test item (between 100°C and 200°C)

The oven temperature was increased to 400°C and temperatures of the sample and the oven were recorded

Results (see graphic):

The temperature of the sample did not reach 400°C by increasing the temperature of the oven to 400°C and therefore no relative self-ignition temperature was measured. 

Fumes were observed between 100°C and 200°C. The wire mesh cube and the test item were visually checked after the determination. There was no test item left in the wire mesh cube at the end of the measurement. 

Conclusions:

No relative self-ignition was recorded as no ignition occurred up to the complete removal of the test item in the wire mesh cube (between 100°C and 200°C).

Executive summary:

A study was performed to determine the relative self-ignition temperature of the test item P-MENTHANE-1,8-DIOL. The method followed was designed to be compliant with the Commission Regulation (EC) No 440/2008, Method A.16: ''Relative Self-Ignition Temperature for Solids''.

A certain volume of the substance under test is placed in an oven at room temperature; the temperature/time curve relating to conditions in the centre of the sample is recorded while the temperature of the oven is increased to 400°C, or to the melting point if lower, at a rate of 0.5°C/min. For the purpose of this test, the temperature of the oven at which the sample temperature reaches 400°C by self-heating is called the self-ignition temperature. 

The temperature of the sample did not reach 400°C by increasing the temperature of the oven up to 400°C and therefore no relative self-ignition temperatures was measured. Fumes were observed between 100°C and 200°C. The wire mesh cube and the test item were visually checked after the determination. There was no test item left in the wire mesh cube at the end of the measurement. 

In conclusion, no relative self-ignition was recorded as no ignition occurred up to the complete removal of the test item (between 100°C and 200°C).

Description of key information

No relative self-ignition was recorded as no ignition occurred up to the complete removal of the test item (between 100°C and 200°C)

Additional information

A well performed study was conducted according to EU A.16 guideline and under GLP to determine the self-ignition temperature. The result was considered as reliable without restriction.
