Mount the capacitors with the vents up to reduce the amount of electrolyte expelled if a vent operates. Aluminum electrolytic capacitors are normally polarized and require correct-polarity installation in the circuitry. To ensure correct mounting and identification of the polarity, put a clear + and/or – on the board layout marking.
This variation itself is also dependent on the rated voltage and capacitor size. For aluminum electrolytic capacitors, capacitance is measured as the capacitance of the equivalent series circuit at 25 oC in a measuring bridge supplied by a 120 Hz source free of harmonics with maximum AC signal voltage of 1 Vac and no bias voltage.

Insulation resistance is no less than 100 MΩ after 2 minutes electrification with 100 volts applied between the foil and the capacitor case. Not relevant for capacitors with solid electrolyte.
With non-solid electrolyte aluminum electrolytic capacitors the aluminum cases connect to the negative terminals by contact with electrolyte. The resulting isolation resistance may vary from a few ohms to a few thousand ohms. For axial leaded capacitors and flatpacks the case is connected to the negative lead.
