cPs equates to cSt on a 1:1 basis, hence kinematic viscosity is considered to be in the range of 51 to 57 cSt at 25 deg C. It is anticipated that a temperature increase of 15 deg C will not be sufficient to lower the viscosity to < 20,5 mm 2 /s or less. Classification as "H304: May be fatal if swallowed and enters airways" is not applicable.

Conclusions:
Brookfield viscometer was used to determine the dynamic viscosity of Heptanal, oligomeric reaction products with aniline.
Under the conditions of the experiment it was concluded that the test substance has a dynamic viscosity of between 51.0 - 57.0 cPs when measured at 25°C.
