DC. resistance Must be within the specified shall not exceed allowable range or 1% of
tolerance resistance tolerance
(Sub-clause 4.5)
Resistors shall be clamped in the trough of
Insulation Insulation resistance is a 90° metallic V-block or foil method use a metal
resistance
10,000 MΩ Min
foil shall be wrapped closely around the body of
the resistor. After that shall be tested at DC potential
respectively specified in the above list for 60 +10/-0 secs.
