Guideline:
EU Method A.1 (Melting / Freezing Temperature)
Deviations:
no
GLP compliance:
yes (incl. certificate)
Type of method:
other: photocell detection
Key result
Melting / freezing pt.:
>= 85.2 - <= 88.9 °C
Decomposition:
no
Sublimation:
no

Interpretation of results

The mean of at least three measurements, which are in the range of the estimated accuracy, is reported as the melting temperature.

If the difference between the temperature at the beginning and at the final stage of melting is within the limits of the accuracy of the method, the temperature at the final stage of melting is taken as the melting temperature; otherwise the two temperatures are reported.

If the substance decomposes or sublimes before the melting temperature is reached, the temperature at which the effect is observed shall be reported.

Apparatus : Automated Mettler Toledo MP70 Melting Point System
