Specific details on test material used for the study:
Name: Reaction mass of 2-methylbutyl butyrate and pentyl butyrate
EC number: 908-712-1
Description: Clear Colourless to Pale Yellow Liquid
Purity: 99.8%
Storage conditions: Controlled room temperature (15-25 °C, ≤ 70% relative humidity)
Flash point:
64.4 °C
Atm. press.:
101.325 kPa
Remarks on result:
other: ± 0.61°C

Preliminary test was performed from 30 to 200 °C with a positive result. The flash point obtained during the preliminary test was found to be 64.8°C.  

The test item was measured in the main test with three parallels from 50°C.

The three individual measured flash point temperatures were 64.8°C, 63.7°C and 64.7°C. The formal flash point of the test item was given as the mean of the threemeasured temperature values its standard deviation.

The flash point of the Reaction mass of 2-methylbutyl butyrate and pentyl butyratemwas found to be 64.4 ± 0.61°C.

Main test Flash point temperature (°C)
1 64.8
2 63.7
3 64.7
Mean 64.4 ± 0.61
Interpretation of results:
GHS criteria not met
Conclusions:
The flash point of the Reaction mass of 2-methylbutyl butyrate and pentyl butyrate was found to be 64.4 ± 0.61°C.
Executive summary:

In the course of this study an important physico-chemical property, the flash point of test item was determined. The flash point provides a simple, convenient index for assessing the flammability of a wide variety of materials.

The test was performed by use of a MINIFLASH automatic flash point tester with the continuously closed cup – electric arc method according to ASTM D6450. 

The flash point of the test item (Reaction mass of 2-methylbutyl butyrate and pentyl butyrate) was found to be 64.4 ± 0.61°C.

The results indicate that the registered substance does not meet the criteria for flammable liquids in accordance with the Classification, Labelling, and Packaging (CLP) regulation (1272/2008).
