How to use test probe 13 of IEC 61032
We are professional test probe finger manufacturersAccording to IEC 60335-1 Clause 8.1.3, appliances shall be constructed and enclosed so that there is adequate protection against accidental contact with live parts.

Test probe 13 of IEC 61032 is applied without appreciable force through openings in class 0 appliances, class II appliances and class II constructions, except for those giving access to lamp caps and live parts in socket-outlets.

The test probe is also applied through openings in earthed metal enclosures having a nonconductive coating such as enamel or lacquer.

It shall not be possible to touch live parts with the test probe.

Mechanical Strength Testing on Plug-ballast/transformers and mains socket-outlet-mounted luminaires
Corform to the IEC 60598 clause 4.13.6,plug-ballast/transformers and maina socket-outlet-mounted luminaires shall have adequte mechanical strength.

Compliance is checked by the tumbling barrel testing,the ballel is turned at a rate of five revolutions per minute,ten falls per minute thus taking place,the sample falls from a height of 500mm onto a steel plate 3 mm thick,the number of falls being:

--50 if the mass of the sample does not exceed 250 g;

--25 if the mass of the sample exceeds 250 g.

After the test, the sample shall show no damage within the sense of this standard,but it need not be operative and any damage to the glass bulb shall be ignored,provided that the protection against electric shock is not affected, small pieces whick may have broken off the sample are ignored.

The ZLT Tumbling Barrel Tester,Model ZLT-GT1, conform to the IEC 60598 figure 25.

How choice of the Impact Test Apparatus
How choice of the impact test apparatus?

According to thd IEC 68-2-75 standard,the choice of the test apparatus depends on the orientation of the surface to be tested and on the energy level.Not all mechods can be used in every case.It is self-evident that a pendulum hammer can only used on vertical surfaces without overhangings.Similarly the vertical hammer can normally only be used on accessible horizontal surfaces.When the speciment cannot be moved or turned, for any reason,the choice is limited.The advantage of the spring hammer is that it can be used in any position,provided there is enough room to apply it correctly, and that the specified impact energy does not exceed 2J.For highter energy levels, a spring hammer would be too difficult to handle, and could even be hazardous for the operator.

The Mechanical Strength Test for Information Technology Equipment
According to IEC 60950 standard, equipment shall have adequate mechanical strength and shall be so constructed that no hazard is created in the meaning of this standard when subjected to handling as may be expected.

Compliance is checked by test as specified below :

1 Steady force test, 10 N
2 Steady force test, 30 N
3 Steady force test, 250 N
4 Steel ball impact test
5 Drop test

The Required Glow Wire Test Temperature for Internal Parts of Insulating Material
According to IEC 61558 clause 27.3.2 , internal parts of insulating materials retaining (keeping in position) current carrying parts in position shall be resistant to ignition and spread of fire.

Compliance is checked by subjecting the parts of insulating materials to the glow wire tester with the temperature of the glow wire as follows:

– 550 °C for internal insulating material not retaining (not keeping in position) current carrying parts in position
– 650 °C for coil formers
– 650 °C for parts retaining (keeping in position) current carrying parts in position and terminals for external conductors which carry a current up to 0,2 A during normal operation
– 750 °C for parts retaining (keeping in position) current carrying parts in position and terminals for external conductors with fixed connection (e.g., soldering) which carry a current exceeding 0,2 A during normal operation
– 850 °C for parts retaining (keeping in position) current carrying parts in position and terminals for external conductors with non fixed connection which carry a current exceeding 0,2 A during normal operation
The Glow Wire Tester ZLT-GTR produced by Zhilitong Electromechanical Co., Ltd , can carry out glow wire test at temperature of 550 °C, 650 °C,750 °C and 850 °C.
