Key result

Flash point:

47 °C

Atm. press.:

ca. 101.3 kPa

Remarks on result:

other: Mean of the two determinations

Results:

Pre-test:

The flash point of the test item was estimated at 48.0°C during the pre-test.

First determination:

The flash point of the test item was estimated at 46.0°C during the first determination.

An automatic correction was applied to the obtained result because the ambient pressure was not 101.3 kPa but 98.1 kPa.

With this correction, the flash point value is 47.0°C at 101.3 kPa.

Second determination:

The flash point was detected at 47.0°C and the same automatic correction was applied because the ambient pressure was still 98.1 kPa.

With this correction, the flash point value is 48°C at 101.3 kPa.

Interpretation of results:

Category 3 (flammable liquids) based on GHS criteria

Conclusions:

The corrected flash point of REACTION MASS OF 1,4-CINEOLE AND 1,8-CINEOLE is 47.0°C at 101.3 kPa (lowest value of two independent determinations).

Executive summary:

A study was performed to determine the flash point of the test item REACTION MASS OF 1,4 -CINEOLE AND 1,8 -CINEOLE. The method followed was designed to be compliant with the Method A.9 of Commission Regulation No. 440/2008, ''Flash Point''.

The flash point of the test item is determined with a closed cup tester, by an equilibrium method called "Small Scale", (commonly known as Setaflash).

The substance is placed into a test cup and heated using a temperature gradient program. Ignition trials are carried out in order to ascertain whether or not the sample flashes at the temperature tested.

A pre-test followed by two determinations were conducted. For the pre-test, a flash point of 48.0°C was observed. This data was used to select the range of temperatures for the following determinations.

Determinations 1 and 2 respectively gave a corrected flash point of 47.0°C at 101.3kPa and 48.0°C at 101.3kPa.

The flash point of the test item was determined to be 47.0°C at 101.3 kPa (lowest value of two independent determinations).

Description of key information

The flash point of REACTION MASS OF 1,4-CINEOLE AND 1,8-CINEOLE was determined to be 47°C.

The substance is classified as flammable (R10) according to Directive 67/548/EEC (DSD) and as flammable liquid Cat. 3 according to Regulation (EC) No 1272/2008 (CLP).

Key value for chemical safety assessment

Flash point at 101 325 Pa:

47 °C

Additional information

The flash point of REACTION MASS OF 1,4-CINEOLE AND 1,8-CINEOLE was determined in a study performed according to EU method A.9. As the results were obtained under GLP without deviation, they were considered as valid and reliable without restriction and used as key value.
