Endpoint:

flash point of flammable liquids

Type of information:

experimental study

Adequacy of study:

key study

Study period:

2013-10-30

Reliability:

1 (reliable without restriction)

Rationale for reliability incl. deficiencies:

test procedure in accordance with national standard methods

Qualifier:

according to guideline

Guideline:

other: JIS K2265-1: Determination of flash point-Part 1:Tag closed cup method

Version / remarks:

2007

Deviations:

no

GLP compliance:

no

Type of method:

closed cup

Flash point apparatus:

Tag apparatus

Key result

Flash point:

> 94 °C

Atm. press.:

101.7 kPa

A preliminary test was performed using the Tag closed cup flash point tester and no flash was observed up to 94 °C. Therefore, the main study was not performed. The atmospheric pressure on the day of the test: 101.7 kPa Corrected flash point: > 94 °C

Interpretation of results:

GHS criteria not met

Conclusions:

In conclusion, the flash point corrected to an atmospheric pressure of 101.3 kPa of the test substance is > 94 °C under the conditions of the test.

Executive summary:

A study was conducted according to JIS K2265-1:2007 to determine the flash-point of the test item. Therefore, a Tag closed cup flash-point tester was used. The test cup was filled with the test item and heated with a temperature rise of 5 - 6 °C/min. The test flame was applied so that the flame was lowered into the vapour space of the cup in 0.5 s, left in its lowered position for 1 s, and quickly raised to its high position. The sample was not stirred while the test flame was applied. No flash was observed up to 94 °C. In conclusion, the flash point of the test substance is > 94 °C under the conditions of the test.

Key result

Flash point:

150 °C

Atm. press.:

101.1 kPa

A preliminary test was performed using the Cleveland open cup flash point tester and a flash point of 150 °C was found. In the main test, the test flame was applied at each 2 °C temperature rise. The atmospheric pressure on the day of the test was 101.1 kPa. The results of the main test are summarised in the table. The corrected flash point was determined to be 150 °C.

 

Test	Observed
1	150 °C
2	150 °C
Mean	150 °C

Interpretation of results:

study cannot be used for classification

Conclusions:

In conclusion, the mean flash point of the test substance at an atmospheric pressure of 101.3 kPa is 150 °C under the conditions of the test.

Executive summary:

A study was conducted according to JIS K2265-4:2007 and ISO 2592:2000 to determine the flash-point of the test item. Therefore, a Cleveland open cup flash-point tester was used. The test cup was filled with the test item and heated with a temperature rise of 5-6 °C/min. The test flame was applied so that the flame was lowered into the vapour space of the cup in 0.5 s, left in its lowered position for 1 s, and quickly raised to its high position. The sample was not stirred while the test flame was applied. In two tests of the main study a flash was observed at 150 °C. In conclusion, the mean flash point of the test substance at an atmospheric pressure of 101.3 kPa is 150 °C under the conditions of the test.

Description of key information

In conclusion, the flash point corrected to an atmospheric pressure of 101.3 kPa of the test substance is > 94 °C under the conditions of the Tag closed cup method. Under the conditions of the Cleveland open cup test, the mean flash point of the test substance at an atmospheric pressure of 101.3 kPa was determined to be 150 °C.
