Key result

Flash point:

63 °C

Atm. press.:

1 013 hPa

Preliminary Test

The estimated flash-point of the test item was 61°C.

Maint test:

The difference between the results obtained with the Test 1 and Test 2 was ≤ 2°C. From this, it was concluded that the flash-point of the test item is the lowest flash-point obtained.

Test	Flash-point [°C]	Lowest flash-point [°C]
1	63	63
2	63

Interpretation of results:

Category 4 (combustible liquids) based on GHS criteria

Conclusions:

The flash-point of the test item was 63°C.

Executive summary:

The flash-point of the test item was determined in a GLP-compliant study performed in accordance with EC A.9 Method and other standards methods, using a closed cup method. The flash-point of the test item was 63°C.

Description of key information

The flash-point of the test item was determined in a GLP-compliant study performed in accordance with EC A.9 Method and other standards methods, using a closed cup method. The flash-point of the test item was 63°C.

The flash point was also determined in two supporting studies performed either with to recognized guideline (EN IS0 3680) and reporting a flash point of 61°C or with the Tag Closed Cup tester according to Japanese Fire service Act method and reporting a flash point of 67.5°C.

Key value for chemical safety assessment

Flash point at 101 325 Pa:

63 °C

Additional information

All the available data are consistent supporting 1,6-divinylfluorohexane has a flash point in the range from 61 to 67.5°C. 

The GLP-compliant study performed in accordance with standard methods without deviations is selected as a key study for the endpoint. The non-GLP studies are also reported for the endpoint and selected as supporting study (Klimisch 2).

Conclusion for flammable liquid haz,ard:

Based on the flash point value > 60°C the substance is not classified as flammable liquid in EU regulation and it is classified as flammable liquid Cat.4 in GHS UN regulation.
