Specific details on test material used for the study:

SOURCE OF TEST MATERIAL
- Source and lot/batch No.of test material: PDC Lot 1, Pail 2
- Expiration date of the lot/batch: 23 Mar 2006
- Purity: 99.959%
- Synonyms: MTDID 665
STABILITY AND STORAGE CONDITIONS OF TEST MATERIAL
- Storage condition of test material: room temperature in the dark

Key result

Atm. press.:

102.1 kPa

Remarks on result:

no flash point - measurement carried out until boiling temperature

Remarks:

sample boiled at 97 °C

Boiling was confirmed visually.

Interpretation of results:

GHS criteria not met

Conclusions:

HFE s-601 has no flash point below its boiling temperature or 97 °C by Pensky-Martens closed cup test (EU method A.9).

Executive summary:

No flash-point could be determined using the Pensky-Martens closed cup method. No flammable vapour/air mixture was produced in the test vessel at temperatures below boiling, which was observed visually at 97 °C, 102.1 kPa. The study was conducted in accordance with EU method A.9 and was GLP compliant; therefore the study is considered reliable without restrictions and is suitable for Classification & Labeling and Risk Assessment.

Summary autoignition test results from three trials in the main test

Test number (atm pressure)	Test volume (µL)	Autoignition temperature (°C)	Time lag (s)
Test 1	70	418	15
(102.41 kPa)	125	410	24
	250	418	23
Test 2	70	420	16
(102.48 kPa)	150	412	33

Test 3	50	418	12
(101.66 kPa)	140	411	24
	250	404	22
	300	407	19

Conclusions:

The autoignition temperature of HFE s-601 is 400 °C (EU A.15)

Executive summary:

In a test of HFE s-601 done per EU test method A.15 and DIN 51794, the lowest observed autoignition temperature was 404 °C. This value was rounded down to 400 °C per DIN 51794 practice. The study was conducted in accordance with accepted guidelines and was GLP compliant; therefore the study is considered reliable without restrictions.
