Any other information on results incl. tables

The measured flash point value for the reference substance glycerol, 191°C is within the control cards limits and complies with the validation criteria of 195.0+/-4.0°C.

The flash point of the reference substances CRM, 74.5 °C respects also the checking cards limits and complies with the validation criteria of 73.9 +/- 2 °C

The flash point of the test item was estimated at 136.0°C during the pre-test.

The flash point of the test item was estimated at 140.0°C during the first determination. An automatic correction was applied to the obtained result because the ambient pressure was not 101.3 kPa but 97.5 kPa. With this correction, the flash point value is 141.0°C at 101.3 kPa.

The flash point was detected at 142.0°C and the same automatic correction was applied because the ambient pressure was 97.4 kPa. With this correction, the flash point value is 143°C at 101.3 kPa.

The results of the two determinations (141°C and 143°C at 101.3 kPa) meet validation criteria (no more than 2°C of difference). Therefore, the results are considered as valid. The corrected flash point of the test item was determined to be 141°C at 101.3 kPa (lowest value of two independent determinations).

Applicant's summary and conclusion

Interpretation of results:

GHS criteria not met

Conclusions:

The corrected flash point of the test item was determined to be 141.0°C at 101.3 kPa (lowest value of two independent determinations).

Executive summary:

A study was performed to determine the flash point of the test item Triisononylamine. The method followed was designed to be compliant with the Method A.9 of Commission Regulation No. 440/2008, “Flash Point” and followed GLP.

The flash point of the test item is determined with a closed cup tester, by an equilibrium method called “Small Scale” (commonly known as Setaflash). The substance is placed into a test cup and heated using a temperature gradient program. Ignition trials are carried out in order to ascertain whether or not the sample flashes at the temperature tested. A pre-test followed by two determinations were conducted. For the pre-test, a flash point of 136.0°C was observed. This data was used to select the range of temperatures for the following determinations. Determinations 1 and 2 respectively gave a corrected flash point of 141°C and 143°C at 101.3 kPa.

Moreover the flash point of the reference substances glycerol and CRM respects the checking cards limits.

The corrected flash point of the test item was determined to be 141°C at 101.3 kPa (lowest value of two independent determinations).
