The results of the main study on the determination of the flash-point of the test item are given in Table 4.

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.

Table 4        Main Study: Flash-point of the Test Item

Test	Flash-point [°C]	Lowest flash-point [°C]
1	165	163
2	163

Interpretation of results:

GHS criteria not met

Conclusions:

The flash-point of the test item was 163°C

Executive summary:

The closed cup method was applied for the determination of the flash-point of the test item. The difference between the results obtained with the Test 1 (165°C) and Test 2 (163°C) was ≤2°C. From this, it was concluded that the flash-point of the test item is the lowest flash-point obtained i.e. 163°C.
