The preliminary study and measurements were performed under atmospheric
pressure of 1017 hPa. In order to determine the melting temperature
range for PRODUCT P-1401, the preliminary study was carried out in the
temperature range: 30.0 °C – 200.0 °C. In the course of the study,
darkening of the test item was observed (about 200.0 °C, gradient
temperature – 20.0 °C/min). The study was repeated for the three
measurement series. Initially at the temperature of 71.4°C the samples
started darkening (dark yellow), above 170° C the color of the samples
were brown. About 200 °C the structures of the samples were disturbed
(the samples shrank) and the gaseous products were observed (some
bubbles). The samples were dark brown. No melting point was visually
observed up to the end of heating: 400 °C, when the final color was deep
brown/graphite. It is suggested that all samples started to decompose
about 200.8 °C (gradient temperature: 0.5 °C/min). The accuracy of the
apparatus is defined as: up to 250.0 °C is equal to 0.3 °C, 250.0 -
400.0 °C is equal to 0.3 °C - 0.5 °C). In this study, the accuracy of
the apparatus was equal to 0.3 °C.

The determination of the melting point was performed according to the
OECD Guideline 201 (GLP study). The capillary tube in heated metal block
method and BÜCHI Melting Point M-565 apparatus was used. The
decomposition of the test item was observed at a temperature of 200.8 °C
and 1017 hPa. No melting temperature was observed up to 400 ºC.
Key study: Test method OECD Guideline 201. GLP study. The decomposition of the test item was observed at a temperature of 200.8 °C and 1017 hPa. No melting temperature was observed up to 400 ºC.
