Component for conducting or receiving a fluid and method for testing the component

A method for testing a component, the method comprising the following steps:

• providing a component for conducting or receiving a fluid, the component having a wall including:
• a carrying structure composed of a glass fiber reinforced plastic, the carrying structure having inner and outer surfaces;
• electrically insulating inner and outer protective layers each disposed on a respective one of the inner and outer surfaces of the carrying structure;
• an electrically conductive inner intermediate layer having an electrical terminal and being disposed between the inner protective layer and the carrying structure;
• and
• an electrically conductive outer intermediate layer having an electrical terminal, being insulated electrically from the inner intermediate layer and being disposed between the outer protective layer and the carrying structure;
• admixing an additive for a measurement duration to increase a conductivity of the fluid conducted or received by the component during a measurement process;
• and
• detecting an electrical resistance between the outer and inner intermediate layers.
