Key result

Flash point:

157 °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 159 .0°C during the pre-test.

First determination:

The flash point of the test item was estimated at 156.0°C during the first determination.

An automatic correction was applied to the obtained result because the ambient pressure was not 101.3 kPa but 97.8 kPa.

With this correction, the flash point value is 157.0°C at 101.3 kPa.

Second determination:

The flash point was detected at 156.0°C and the same automatic correction was applied because the ambient pressure was still 97.8 kPa.

With this correction, the flash point value is 157°C at 101.3 kPa.

Conclusions:

The corrected flash point of the test item was determined to be 157.0°C at 101.3 kPa (lowest value of two independent determinations). Therefore, the substance is not classified as flammable according to CLP regulation (EC) No 1272/2008. No signal word or hazard statement is required.

Executive summary:

A study was performed to determine the flash point of the test item TERPENIC OLIGOMERS Batch 16 -03 SI. 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 159.0°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 157.0°C at 101.3kPa.

Moreover the flash point of the reference substances glycerol and CRM respects the checking cards limits.

Therefore, the substance is not classified as flammable according to CLP regulation (EC) No 1272/2008. No signal word or hazard statement is required.

Description of key information

The flash point was determined with a closed cup tester by Setaflash method for terpenic oligomers.

The flash point was determined to be 157.0°C at 101.3 kPa. Therefore, the substance is not classified as flammable according to CLP regulation (EC) No 1272/2008. No signal word or hazard statement is required.

Key value for chemical safety assessment

Flash point at 101 325 Pa:

157 °C

Additional information

The flash point of terpenic oligomers was determined in one 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.
