The figures indicated here are approximate values. They may be affected by the temperature, operating time, concentration and
stress level of the component involved, by mechanical loads, etc., and the user is not released therefore from the obligation of
performing checks and trials of his own. The values indicated here have been compiled on the bases of current experiences and
findings. Any legally binding guarantee of certain properties, or any suitability for a specific application cannot be inferred from
the present data.
