A.

39.4

B.

40.0

C.

39.0

D.

37.6

E.

38.2

Question 9

In order to pass the Drop Test (IEC 61010), the device under test (DUT) must work as intended at the end.

True

False

Question 10 During the Drop Test (IEC 61010), how would you position the DUT (device under test) to ensure that it lands in its most severe condition?

A.

Centre the DUT a certain distance above the wooden board on the floor.

B.

Hold the DUT such that its corner or edge will hit the board first.

C.

Hold the DUT such that its bottom surface will hit the board first.

D.

Ask your partner to hold the measuring tape.

E.

Make sure your feet are not close to the board

In a typical IR Test, for every ____ in temperature, the resistance will _____.

A.

15 °C decrease, halve

B.

5 °C decrease, halve

C.

10 °C increase, double

D.

10 °C increase, halve

E.

15 °C increase, halve

F.

5 °C decrease, double

Answer 1

Question 2:

As per the standard if the device is not in service then it needs to be inspected once in 6 months. So answer is A.

Question 3:

The answer false. Until an electric safe condition is achieved the circuit should not be energized.

Question 4:

The main purpose of Standard CSA Z462 is to specify requirements for a practical safe PPE for workers relative to the hazards arising from the use of electricity.
