(Sub-clause 4.13)
Terminal strength No evidence of mechanical damage
Direct load:
Resistance to a 2.5kg direct load for 10 seconds in the direction of the longitudinal axis of the terminal
leads.
Twist test:
Terminal leads shall be bent through 90° at a point of about 6mm from the body of the resistor and shall be
rotated through 360° about the original axis of the bent terminal in alternating direction for a total of 3
rotations.
(Sub-clause 4.16)
