Flash point
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:
- September 2010
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: Study performed according to international guidelines but not under GLP and with some lack of details (no report number, criteria of validity not indicated).
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.9 (Flash-Point)
- Deviations:
- not specified
- Qualifier:
- according to guideline
- Guideline:
- ISO No., other: ASTM D 3828-97
- Deviations:
- not specified
- GLP compliance:
- no
- Type of method:
- equilibrium method closed cup
- Key result
- Flash point:
- 31 °C
- Atm. press.:
- ca. 1 atm
- Interpretation of results:
- Category 3 (flammable liquids) based on GHS criteria
- Conclusions:
- The flash point of substance alpha-pinene multiconstituent is 31°C.
Therefore, the substance is classified as flammable category 3 (H226) according to Regulation (EC) n°1272/2008 (CLP) and as flammable (R10) according to Directive 67/548/EEC (DSD). - Executive summary:
The flash point was determined with a closed cup tester by an equilibrium method "Small Scale", commonly known as Setaflash where the vapours are deemed to be in temperature equilibrium with the liquid. The study was based on the procedures indicated by the following internationally accepted methods:
- ASTM D 3828 -97: Standard Test Methods for Flash Point by Small Scale Closed Tester.
- EU method Part A, A.9
Two measurements were performed.
The flash point of substance alpha-pinene multiconstituent has been measured as 31°C.
Therefore, alpha-pinene multiconstituent is classified as flammable category 3 (H226) according to Regulation (EC) n°1272/2008 (CLP) and as flammable (R10) according to Directive 67/548/EEC (DSD).
- Endpoint:
- flash point of flammable liquids
- Type of information:
- read-across from supporting substance (structural analogue or surrogate)
- Adequacy of study:
- supporting study
- Justification for type of information:
- α-Pinene is a bicyclic monounsaturated monoterpene and (-)-α-pinene is an enantiomeric form of α-pinene. Therefore, data on (-)-alpha pinene can be extrapolated to alpha-pinene. (see read-across justification document in section 13).
- Reason / purpose for cross-reference:
- read-across source
- Flash point:
- 31.3 °C
- Atm. press.:
- ca. 1 atm
- Interpretation of results:
- Category 3 (flammable liquids) based on GHS criteria
- Conclusions:
- The flash point of (-)-alpha-pinene was determined to be 31.3°C.
Therefore, the substance is classified as flammable category 3 (H226) according to Regulation (EC) n°1272/2008 (CLP) and as flammable (R10) according to Directive 67/548/EEC (DSD). - Executive summary:

The measured values for the reference substances were:
Flash point of butanol: 36.0°C and 36.0°C
Flash point of N,N dimethylformamide: 58.1°C and 59.0°C
Flash point of Setaflash Certified Material 99878 -3: 74.3°C and 75.0°C
The measured values for the test item were : 31.2 °C and 32.0 °C.
According to the Standard Test Method ASTM D 3828 -97 the precision of the method is for a flash point of 149°C as follow:
Repeatability: 2.0°C
Reproductibility: 7.5°C
Available Data for Reference Items:
Flash point of butanol (CAS No. 35296 -72 -1) : 35°C, closed cup (Sigma Aldrich Safety Datat Sheet)
Flash point of N,N Dimethylformamide (CAS No.68 -12 -2) : 58°C, closed cup (Acros Safety Datat Sheet)
Flash point of Setaflash Certified Material 99878 -3 : 74.5°C (Certificate of Measurement provided)
Measured flash point of the test item and reference items (°C):
| Substance or mixture | Assay No.1 | Assay No.2 |
| (-)-ALPHA PINENE | 31.3 | 31.3 |
| butanol (CAS No.35296 -72 -1) | 35.8 | 35.4 |
| N,N Dimethylformamide (CAS No.68 -12 -2) | 57.7 | 57.5 |
| Setaflash Certified Material 99878 -3, batch 161506E | 74.3 | 75.0 |
According to the results obtained with the reference items, the test has to be considered as valid.
Description of key information
Flash point of alpha-pinene multiconstituent: 31°C
Key value for chemical safety assessment
- Flash point at 101 325 Pa:
- 31 °C
Additional information
The flash point of alpha-pinene multiconstituent was determined in a study performed according to ASTM D 3828-97 method and EU method A.9.
The value was considered with a reliability of 2 (reliable with restrictions) because the result is scientifically acceptable but not obtained under GLP and some details were lacking in the report. However the measured flash point is valid for key value and supported by consistent experimental data obtained with (-)-alpha-pinene.
