- SOURCE OF TEST MATERIAL
- Batch No.of test material: AN-0400-105
- Expiration date of the lot/batch: 01 January 2019
- Purity test date: 100%
STABILITY AND STORAGE CONDITIONS OF TEST MATERIAL
- Storage condition of test material: Approximately -20 °C under nitrogen in the dark
- Key result
- Flash point:
- 272 °C
- Atm. press.:
- 102 kPa
- Remarks on result:
- other: ± 2
- Conclusions:
- The flash point of the test item was determined to be 272 ± 2°C.
- Executive summary:
The flash point of the test substance, Resin acids and Rosin acids, esters with trimethylolpropane, was determined using a closed cup flash point tester, in a procedure compatible with Methold A.9 Flash Point of Commission Regulation (EC) No 440/2008 of 30 May 2008.
The apparatus used was the Setaflash 30000 -0 flash point tester. An aliquot of the test substance (approximately 2g for temperatures up to 100°C and approximately 4g for temperatures above 100 °C) was transferred to the sample cup of the Setaflash tester. Observations were made for ignition of the vapour and if ignition did not occur, then the temperature was increased and the test flame was re-introduced. This process was repeated until the lowest reproducible temperature at which a flash occurred, using a fresh sample.
The recorded flash point was corrected for atmospheric pressure using the following equation: Corrected flash point = Observed flash point [C] + 0.23 (101.325 - ambient atmospheric pressure (kPa) [p]). Using this equation, the flash point was determined to be 272 ± 2°C at an atmospheric pressure of 102.0 kPa.

Using this equation, the flash point was determined to be 272 ± 2°C at an atmospheric pressure of 102.0 kPa.
Key value for chemical safety assessment
- Flash point at 101 325 Pa:
- 272 °C
