Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

- 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).
Reference
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).
