- Version / remarks:
- (adopted 27 July 1995)
- Deviations:
- no
- Principles of method if other than guideline:
- In a measurement with differential scanning calorimetry (DSC) a sample of the test item and a reference material (identical crucible without the test
item) are subjected to the same controlled temperature program. The difference in the temperatures of the test item and the reference material is the original measurement signal which is internally assigned to the heat flow rate. The heat flux DSC belongs to the class of heat-exchanging
calorimeters. A defined exchange of the heat to be measured takes place via a thermal resistance. In contrast in the power compensation DSC, the
heat to be measured is compensated with electric energy, by increasing or decreasing an adjustable heating power.
When the sample undergoes a transition involving a change in enthalpy, for example an endothermic melting or boiling transition, that change is
indicated by a departure from the base line of the heat flow record. The peak area is proportional to the change in enthalpy. - GLP compliance:

Description of key information
Read across to the individual substances n-Nonyl methacrylate, i-Nonyl methacrylate, n-Decyl methacrylate (n-DMA), i-Decyl methacrylate (i-DMA), n-Lauryl methacrylate (n-LMA) and n-Tetradecyl methacrylate (n-TDMA) of NUMA UVCB substance and structural analogue substances of NUMA 2 -Ethylhexyl methacrylate (2 -EHMA) and LIMA UVCB substance (C12 -C16 methacrylate, CAS: 90552 -02 -6):
The melting temperature of the structural analogue 2-Ethylhexyl methacrylate showed a melting point below -50°C (experimental result according to OECD 102).
For iso-decyl methacrylate no melting point was determined, glass transition temperature: -116 °C (experimental result according to OECD 102, the melting point could not be determined).
For n-dodecyl methacrylate (only an impurity of NUMA UVCB substance) a melting point of -7°C was published. (Brandes E., Möller W. (2003), Narbert, Schön (2004)).
The physicochemical properties of the constituents of NUMA are showing a regular pattern. With increasing chain length, the melting points increase. Therefore it can be anticipated that the melting point of NUMA UVCB substance is < -7 °C.
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- -7 °C
Additional information
The melting temperature of the structural analogue 2-Ethylhexyl methacrylate showed a melting point below - 50 °C. For n-Decyl methacrylate, a transition temperature of - 116 °C was experimentally determined and for n-dodecyl methacrylate a melting point of -7 °C was published. Therefore a melting point below -7 °C can be anticipated for NUMA UVCB substance as worst case..
