Flame test : The test flame shall be applied and removed for each 15
sec respectively to repeat the cycle 5 times.
Overload flame retardant : AC voltage corresponding to 2, 4, 8, 16 and
32 times the power rating shall be applied for each 1min. until
disconnection occurs.
However the applied voltage shall not exceed the value of 4 times
the maximum operating voltage.
Test Methods
Flame retardant
No evidence of flaming or
self-flaming.

■Precautions for Use
・
Coating color, marking and dimensions are different depending on the manufacturing base. Verify them on the delivery specification.
・
Be careful to handle these resistors because outer coatings are comparatively weak to outer shock due to flameproof special coats. Please wash them to a
minimum. No external force is given to the coating films until they are well dried because the coating films become weaker right after washing. The original
strength will be returned after they are dried, so please pay attention not to apply any external force onto the coating film of resistors for 20 minutes after
drying. Especially no PC boards shall be piled up.
