Reference

Reference 1

Endpoint:

flash point of flammable liquids

Data waiving:

study technically not feasible

Justification for data waiving:

the study does not need to be conducted because the flash point is only relevant to liquids and low melting point solids

Justification for type of information:

JUSTIFICATION FOR DATA WAIVING
In accordance with section 2 of REACh Annex XI, flash point measurement does not apply to solids. Please refer to Flammability (Flammable solids) under IU Section 4.13.

Reason / purpose for cross-reference:

data waiving: supporting information

Reference 2

Endpoint:

flash point of flammable liquids

Type of information:

experimental study

Adequacy of study:

supporting study

Study period:

2012

Reliability:

1 (reliable without restriction)

Rationale for reliability incl. deficiencies:

guideline study

Remarks:

The study was conducted according to an internationally recognised method. No deviation was reported. The substance is considered to be adequately characterised with its isomers composition. Therefore full validation applies.

Reason / purpose for cross-reference:

reference to other study

Qualifier:

according to guideline

Guideline:

EU Method A.9 (Flash-Point)

Qualifier:

according to guideline

Guideline:

ISO 3679 (Determination of flash point - Rapid equilibrium closed cup method)

Version / remarks:

1983

Qualifier:

according to guideline

Guideline:

ASTM D3278 (Standard test methods for flash point of liquids by small scale closed-cup apparatus)

Version / remarks:

1996

GLP compliance:

no

Type of method:

equilibrium method closed cup

Flash point apparatus:

other: Rapid Flash Tester RT-1

Flash point:

149 °C

Atm. press.:

97.7 kPa

Remarks on result:

other: +/-2°C

Flash point:

150 °C

Atm. press.:

101.325 kPa

Remarks on result:

other: corrected flash point

Preliminary determination: 151°C

Determination 1 (fresh sample): 149°C

Determination 2 (fresh sample): 149°C

Atmospheric pressure = 97.7 kPa

Interpretation of results:

GHS criteria not met

Conclusions:

The study is not suitable for classification purpose according to CLP criteria, as the flash point is not relevant for solids.
However, it confirms that the substance does not evolve flammable vapours upon heating.
Moreover, it is relevant with regard to GHS criteria, as the melting point (ca 65°C) is below the higher threshold (93°C), i.e. the substance is liquid in the classification range. Not a flammable liquid based on result.

Executive summary:

The flash point of the test substance was determined under GLP according to ISO 3679 (listed in EU A9 guideline), closed cup method. Two main runs were performed, and the lower result was corrected to normal atmP.

Normal Flash Point = 150°C.

Normal Flash Point = 151°C.

Description of key information

Flash Point ≥ 150°C, but not relevant for CLP classification purpose (solid).

The substance is NOT classified as a flammable liquid according to GHS criteria.

Key value for chemical safety assessment

Flash point at 101 325 Pa:

150 °C

Additional information

Two fully reliable experimental studies, conducted according to a recognized ISO/EC method, are available for two different compositions. Consistent results (150 and 151°C under normal Patm) were obtained, and confirm that the substance does not evolve flammable vapours upon heating.

However, they are not suitable for classification purpose according to CLP criteria, as the flash point is not relevant for solids (melting point > 60°C which is the highest classification threshold for flammable liquids).

With regard to GHS criteria, the substance is liquid (mp ca 65°C) in the classification range (up to 93°C), but the result does not meet the classification criteria, i.e. Not a flammable liquid.
