enthalpy sample 2

Measured by
ZAE Bayern
Measured with DSC Q2000 (TA Instruments)
Measured according to standard
None
Comment on measurement
No heating/cooling rate tests done. 3 samples with 2 cycles each. 0.1 wt.% nucleating agent added to influence the melting enthalpy as little as possible. Enthalpy: 5% estimated uncertainty. Different integration ranges for the crystallization enthalpy.
