Pre-Test

After evaluation the following values were recorded:

 

Values Pre-Test

Room Temperature

5.5 °C

-20.0 °C

-80 °C

Brown, viscous liquid

Same as

at room temperature

More viscous, nearly frozen but easily pierce-able

Frozen on surface, but pierceable

 

After performance of the pre-test, the sponsor was consulted. As according to REGULATION (EC) No 1907/2006 OF THE EUROPEAN PARLIAMENT AND OF THE COUNCIL, Annex VII, dated 18. December 2006 (and further amendments) by Commission Regulation the determination of the melting / freezing point does not need to be conducted below a lower limit of - 20 °C; no main test was performed.

 

Results and Discussion

In a pre-test, the test item Petroleum Resins (Kendex 0897) was still unfrozen and piercable at – 80 °C.

According to REGULATION (EC) No 1907/2006 OF THE EUROPEAN PARLIAMENT AND OF THE COUNCIL, Annex VII, dated 18. December 2006 (and further amendments) by Commission Regulation the determination of the melting- / freezing point does not need to be conducted below a lower limit of - 20 °C.

Therefore, no additional test was conducted and the melting point is stated as:

< - 80 °C (<193.15 K).

Conclusions:
In a pre-test, the test item Petroleum Resins (Kendex 0897) was still unfrozen and piercable at – 80 °C.
According to REGULATION (EC) No 1907/2006 OF THE EUROPEAN PARLIAMENT AND OF THE COUNCIL, Annex VII, dated 18. December 2006 (and further amendments) by Commission Regulation the determi-nation of the melting- / freezing point does not need to be conducted below a lower limit of - 20 °C.
Therefore, no additional test was conducted and the melting point is stated as: < - 80 °C (<193.15 K).
Executive summary:

Determination of the melting point of Petroleum Resins (Kendex 0897) according to OECD 102 resp. EU A.1

 

Findings and Results:

In a pre-test, the test item Petroleum Resins (Kendex 0897) was still unfrozen and piercable at – 80 °C.

 

According to REGULATION (EC) No 1907/2006 OF THE EUROPEAN PARLIAMENT AND OF THE COUNCIL, Annex VII, dated 18. December 2006 (and further amendments) by Commission Regulation, the determination of the melting/freezing point does not need to be conducted below a lower limit of - 20 °C.

 

Therefore, no additional test was conducted and the melting point is stated as: < - 80 °C (<193.15 K).

Description of key information

The melting point is stated as: < - 80 °C (<193.15 K).

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
-80 °C
