EV.7.7.1 Parts of the vehicle which are 100 mm or less from any Tractive System component must have a resistance to GLV System Ground less than the values specified below.
a. Electrically conductive parts 300 mOhms (measured with a current of 1 A)
Examples: parts made of steel, (anodized) aluminum, any other metal parts
b. Parts which may become electrically conductive 5 Ohm
Example: carbon fiber parts
Carbon fiber parts may need special measures such as using copper mesh or similar to keep the ground resistance below 5 Ohms.
EV.7.7.2 Electrical conductivity of any part may be tested by checking any point which is likely to be conductive.
Where no convenient conductive point is available, an area of coating may be removed.
