Endpoint:
flash point of flammable liquids
Type of information:
experimental study
Adequacy of study:
key study
Study period:
22-11-2000 to 23-11-2000
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
other: Guideline study performed under GLP. All relevant validity criteria were met.
Qualifier:
according to
Guideline:
EU Method A.9 (Flash-Point)
Deviations:
no
Qualifier:
according to
Guideline:
ISO 3679 (Determination of flash point - Rapid equilibrium closed cup method)
Deviations:
no
Qualifier:
according to
Guideline:
ASTM D3278 (Standard test methods for flash point of liquids by small scale closed-cup apparatus)
Deviations:
no
GLP compliance:

Remarks:
inspected: February 2000; signature: April 2000
Type of method:
equilibrium method closed cup
Flash point apparatus:
Setaflash apparatus
Flash point:
95.7 °C
Atm. press.:
101.325 kPa
Remarks on result:
other: observed flash point: 95 °C (conducted at 98.28 kPa) ; Determination corrected to 101.325 kPa
Interpretation of results:
GHS criteria not met
Remarks:
EU criteria not met
Conclusions:
The flash point of the test item has been determined to be 96 ±2 °C at 101.325 kPa.
Executive summary:

The flash point was determined using EU Method A.9 using the small scale closed cup equilibrium method under GLP. An aliquot of the test item was transferred to the sample cup of the Setaflash tester. The sample was heated and allowed to equilibrate at the set temperature. The test flame was introduced into the sample cup for approximately 2 seconds by sliding the cup shutter open. Observations were made for ignition of the vapour. If no ignition occurred, the temperature was increased and the test flame re-introduced. This was repeated until the lowest reproducible temperature at which a flash occurred, using a fresh sample, was determined. The results indicated are representative of the replicated (n ≥ 2) lowest temperature at which the test item, measured under the conditions of this study causes the vapour of the liquid to ignite momentarily. Measurements were corrected to 101.325 kPa pressure. The flash point of the test substance has been determined to be 96 ±2 °C at 101.325 kPa.

Additional information

Key study : EU Method A.9, 2000: The flash point was determined using EU Method A.9 using the small scale closed cup equilibrium method under GLP. An aliquot of the test item was transferred to the sample cup of the Setaflash tester. The sample was heated and allowed to equilibrate at the set temperature. The test flame was introduced into the sample cup for approximately 2 seconds by sliding the cup shutter open. Observations were made for ignition of the vapour. If no ignition occurred, the temperature was increased and the test flame re-introduced. This was repeated until the lowest reproducible temperature at which a flash occurred, using a fresh sample, was determined. The results indicated are representative of the replicated (n ≥ 2) lowest temperature at which the test item, measured under the conditions of this study causes the vapour of the liquid to ignite momentarily. Measurements were corrected to 101.325 kPa pressure. The flash point of the test substance has been determined to be 96 ±2 °C at 101.325 kPa.
