- 59 °C
- Atm. press.:
- 1 013 hPa
- Interpretation of results:
- Category 3 (flammable liquids) based on GHS criteria
- Conclusions:
- The mean flash-point of the test item was determined to be 59 °C.
- Executive summary:
A study was conducted according to Directive 92/69/EEC method A.9, UN Manual of Tests and Criteria Rev.7, 2019, Method 32.4 and OPPTS 830.6315 to determine the flash point of the test item using non-equilibrium closed cup method. For the determination of the initial temperature of flash point measurement a screen test was performed with the test item. The sample was heated from 25 °C using 5.5 °C/min heating rate. Based on this preliminary test the flash point of the test item was determined to be 58.5 °C. In the course of the study two subsequent tests with the test item were carried out. The measured flash points of the test item were 58.5 °C and 58.5 °C, resulting in a mean value of 59 °C.
Reference
The flash point of Dodecane was determined to be 77.5 °C, hardly deviating from the literature value (78.6 °C, ASTM D7094, Table X1.1). For the determination of the initial temperature of flash point measurement a screen test was performed with the test item. The sample was heated from 25 °C using 5.5 °C/min heating rate. Based on this preliminary test the flash point of the test item was determined to be 58.5 °C. In the course of the study two subsequent tests with the test item were carried out. The measured flash points of the test item were 58.5 °C and 58.5 °C, resulting in a mean value of 59 °C. The repeatability criterion was met because the maximum difference between replicate determinations was not more than 2 °C.
Description of key information
The mean flash-point of the test item was determined to be 59 °C.
Key value for chemical safety assessment
- Flash point at 101 325 Pa:
- 59 °C
