- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.9 (Flash-Point)
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- EPA OPPTS 830.6315 (Flammability)
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- other: UN Handbook “Recommendations on the Transport of Dangerous Goods - Manual of Tests and Criteria” Rev. 6, 2015, Method 32.4 “Test methods used for determining flash point and viscosity”
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- non-equilibrium method closed cup
- Flash point apparatus:
- Pensky-Martens apparatus
- Specific details on test material used for the study:
- Batch No.: 08/2016_R_JM
Purity: 97.5 % - Key result
- Flash point:
- 177.5 °C
- Atm. press.:
- 1 013.25 hPa
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- The flash point of the test item was determined to be 177.5 °C (corresponding to 450.7 K).
- Executive summary:
A study was conducted according to Regulation (EC) No 440/2008 method A.9, EPA OPPTS 830.6315 and UN Test MEthods 32.4 to determine the flash point of the test item using a non-equilibrium closed cup method with Pensky-Martens apparatus. A preliminary test was performed with a search program to determine the rough flash point. For the main test about 70 mL of the test item were filled in the cup. The estimated flash point from the preliminary test was used as target temperature for the main test - 181 °C. Two determinations were conducted and the mean of the two results was given as the flash point of the test item. The flash point was determined to be at 177.5 °C (corrected to the standard pressure).
Reference
Pre-Test for Safety
Formation of bubbles was observed at 302.5 °C. The test item changed its colour to yellow. The chain broke at 220 °C. After cooling down, no further changes of the test item were observed. No signs of polymerisation were observed.
