Materials and methods

Principles of method if other than guideline:
Flash point was determined using ASTM D3828. The results of the flammability burning train test, which is applicable to powdery, granular or paste-like substances, cannot be used to argue that there is no flash point for this test substance. The highly viscous nature of this material coupled with the assumption of a low thermal conductivity necessitates the use of an equilibrium closed cup test method. It was assumed that the individual components are near perfectly mixed therefore ASTM D3828 is an appropriate non-agitated test method conforming to the requirements of ISO-3679. This non-agitated method is appropriate only if the assumption of uniform component distribution is valid and provided that the test substance will not tend to form a surface skin during the test.

Results and discussion

Flash point
Flash point:
180.5 °C
Atm. press.:
990 mBar
Remarks on result:
other: Mean corrected flash point temperature (180.5±2°C); Mean observed flash point temperature (180±2°C)

Applicant's summary and conclusion

Mean Corrected Flash Point = 180.5°C
The study and the conclusions which are drawn from it fulfil the quality criteria (validity, reliability, repeatability).
Executive summary:

The Rapid Tester model RT-1, a closed cup apparatus, was used to determine the flash point of the test substance. The mean corrected flash point was 180.5°C
