flash point of flammable liquids
Type of information:
experimental study
Adequacy of study:
key study
Study period:
From August 18 to 26, 1997
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
The study was conducted according to EC/ISO guideline, and under GLP. No deviation affected the quality of the study. The substance is considered to be adequately characterised with its purity. Therefore full validation applies.
according to guideline
EU Method A.9 (Flash-Point)
according to guideline
ISO No., other: ISO 2719, with the Pensky Martens apparatus
Principles of method if other than guideline:
Not applicable
GLP compliance:
(no certificate)
Type of method:
non-equilibrium method closed cup
Key result
Flash point:
84 °C
Atm. press.:
100.1 kPa

Atmospheric pressure

Corrected flash point

Preliminary test


100.1 kPa


First test


100.1 kPa

Second test


100.1 kPa


Accuracy of the method is indicated in the standard:

• repeatability of the method (same operator) : 2 °C (6 °C if flash point > 104 °C),

• reproducibility of the method (different operators) : 3.5 °C (8.5 °C if flash point > 104 °C).

Interpretation of results:
Category 4 (combustible liquids) based on GHS criteria
EU-CLP criteria not met
The substance is NOT classified as flammable liquid according to CLP criteria (>60°C).
GHS Flam.Liq.4 (< 93°C)
Executive summary:

The flash point of the test substance was determined under GLP according to ISO 2719 (listed in EU A9 guideline), non-equilibrium closed cup method (Pensky Martens apparatus°. The test was carried out in duplicate, and the mean measured value was corrected to normal atmospheric pressure. .

The normal flash point of test substance has been determined to be 84 ±2°C.

Description of key information

The substance is NOT classified as flammable liquid according to CLP Regulation criteria.
The substance is classified as FLAMMABLE LIQUID category 4 according to UN GHS criteria.

Key value for chemical safety assessment

Flash point at 101 325 Pa:
84 °C

Additional information

A fully reliable experimental study, conducted according to a recognized EU method (closed cup) and under GLP, is available. It is considered as a key study, and the result is retained as key data.

This study is relevant for the classification regarding flammable properties.
