Administrative data
Link to relevant study record(s)
- Endpoint:
- flash point of flammable liquids
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 31 October 2017 to 19 December 2017
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.9 (Flash-Point)
- Qualifier:
- according to guideline
- Guideline:
- ASTM D93 (Standard test methods for flash point by pensky-martens closed cup tester)
- Qualifier:
- according to guideline
- Guideline:
- ISO 2719 (Determination of flash point - Pensky-Martens closed cup method)
- Qualifier:
- according to guideline
- Guideline:
- ISO 3679 (Determination of flash point - Rapid equilibrium closed cup method)
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- closed cup
- Flash point apparatus:
- other: Eraflash flash-point tester (Eralytics, Vienna, Austria)
- Specific details on test material used for the study:
- SOURCE OF TEST MATERIAL
- Source and lot/batch No.of test material: Sponsor and 10037-115-5
- Expiration date of the lot/batch: 06 June 2019
- Purity test date: 06 June 2017 - Key result
- Flash point:
- 25 °C
- Atm. press.:
- ca. 1 atm
- Interpretation of results:
- Category 3 (flammable liquids) based on GHS criteria
- Conclusions:
- The closed cup method was applied for the determination of the flash-point of Trimethoxyboroxine (TMBX).
Since the flash-point of the test item was in the range in the range of 23°C +/- 2°C the equilibrium method was applied. The flash-point of the test item obtained with the equilibrium method was 25°C.
Reference
The results of the main study on the determination of the flash-point of the test item are given inTable 5.
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.

Description of key information
The closed cup method was applied for the determination of the flash-point of Trimethoxyboroxine (TMBX).
Since the flash-point of the test item was in the range in the range of 23°C +/- 2°C the equilibrium method was applied. The flash-point of the test item obtained with the equilibrium method was 25°C.
Key value for chemical safety assessment
- Flash point at 101 325 Pa:
- 25 °C
