Reference

Endpoint:

flash point of flammable liquids

Type of information:

experimental study

Adequacy of study:

key study

Study period:

23 January - 22 April, 2015

Reliability:

1 (reliable without restriction)

Rationale for reliability incl. deficiencies:

guideline study

ISO 2719 (Determination of flash point - Pensky-Martens closed cup method)

Version / remarks:

2002

Principles of method if other than guideline:

Not applicable

GLP compliance:

yes (incl. QA statement)

Remarks:

UK GLP compliance programme (inspected on 05 February 2014 / signed on 07 October 2015)

Type of method:

closed cup

Key result

Flash point:

142 °C

Atm. press.:

1 026 mBar

The barometric pressure at the time of testing was 1026 mbar and, thus, no pressure correction was required (difference less than accuracy).

The duplicate determined flash points of test substance were 142 °C and 144 °C, the lower of which are reported as the flash point for safety assessment reasons.

Interpretation of results:

GHS criteria not met

Conclusions:

As the test substance is still solid at 60°C, the study is not relevant for classification according to CLP criteria.
However, it is relevant for GHS classification purpose, as the melting point is below the classification threshold of 93°C, therefore the substance is liquid in this range.
As the test result is above this criteria, the substance is NOT classified as a flammable liquid.

Executive summary:

The flash point of the test substance was determined under GLP according to ISO 2719 (listed in EU A.9 guideline), using Pensky-Martens closed cup flash point apparatus.

The barometric pressure at the time of testing was 1026 mbar and, thus, no pressure correction was required (difference less than accuracy). The duplicate determined flash points of test substance were 142 °C and 144 °C, the lower of which are reported as the flash point for safety assessment reasons.

 

The flash point of test substance has been determined to be 142 °C.

Description of key information

The substance is NOT classified as flammable liquid according to UN GHS criteria.
CLP criteria do not apply (solid at the upper threshold temperature).

Key value for chemical safety assessment

Flash point at 101 325 Pa:

142 °C

Additional information

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

Despite the substance is solid at ambient temperature, this study is relevant for the classification regarding flammable properties, as low melting point leads to liquid state below the GHS classification temperature criteria.

It is not relevant for classification according to CLP criteria.
