Discussion

The deviations are not within the accuracy limits.

Since the apparatus works well, these high deviations can only be explained by the test substance itself. the deviations are not critical.

According to the DIN the mean value of a test has to be used for the result. In the definition part of the DIN the lowest value of a series of measurements for one batch is the flash point. In the case of trends the mean value is not the correct one, since the lowest value should be given as the correst one.

In ASTM methods a calculation of a mean value is not performed.

For these reasons the mean and the lowest value are given as the results.

Conclusions:

A flash point value of 141-146 °C at 978 hPa was determined in a reliable study conducted according to an appropriate test protocol, and in compliance with GLP.

Description of key information

N-[3-(trimethoxysilyl)propylcyclohexylamine]: 141 - 146 °C at 978 hPa (Pensky Martens, closed cup, EU Method A.9)

Additional information

A flash point value of 141 -146 °C (978 hPa) was determined by closed cup method (Pensky Martens) according to EU Method A.9. In another study measured values of 88 °C (closed cup) and 91 °C (open cup) were determined according to DIN 51755. The lower values determined in the supporting study can be justified by the presence of residual solvent.
