Flash point

Administrative data

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

Cross-reference

Reason / purpose for cross-reference:

data waiving: supporting information

Reference

Endpoint:

melting point/freezing point

Type of information:

experimental study

Adequacy of study:

key study

Study period:

27 Apr 1989

Reliability:

2 (reliable with restrictions)

Rationale for reliability incl. deficiencies:

guideline study without detailed documentation

Qualifier:

equivalent or similar to guideline

Guideline:

EU Method A.1 (Melting / Freezing Temperature)

Qualifier:

according to guideline

Guideline:

other: BASF internal SOP FCC III C1.1

GLP compliance:

yes

Type of method:

capillary method

Key result

Melting / freezing pt.:

> 300 °C

Atm. press.:

1 013 hPa

no

Remarks on result:

not determinable

Conclusions:

Under the study conditions, the melting point was >300°C.

Executive summary:

A study was conducted to determine the melting point of the test substance (capillary viscometer method), in compliance with GLP. Under the study conditions, the melting point was >300°C (Mauss, 1989).
