Applicant's summary and conclusion
- Conclusions:
- The flash point of the test item has been determined to be 156 ± 2 °C.
- Executive summary:
The determination was carried out using a closed cup flash point tester*, using a procedure designed to be compatible with Method A.9 Flash Point of Commission Regulation (EC) No 440/2008 of 30 May 2008.
*Based on, Anon (1983) Paints, Varnishes, Petroleum and Related Products – Determination of Flash Point – Rapid Equilibrium Method,International Standard ISO 3679-2004 (E),Second Edition –2004-04-01,P1-18and Anon (1989) Flash Point of Liquids by Setaflash Closed-Cup Apparatus,ASTM D-3278-89,P1-7.
Conclusion
The flash point of the test item has been determined to be 156 ± 2 °C.
