Detailed Product Description

IEC60065 Clause 8.21 Mandrel Test Device, 10° and 230° Rotate Angle

 

IEC60065:2014 Clause 8.21

8.21 Non-separable thin sheet material shall comply with 26.3 of IEC 61558-1:2009 or with the following:
Three test samples, each individual sample consisting of three or more layers of non-separable thin sheet material forming REINFORCED INSULATION , are used. One sample at a time is fixed to the mandrel of the test fixture (Figure 14) as shown in Figure 15.
A downward force of 150 N ± 10 N is applied to the free end of the sample (see Figure 16),
using an appropriate clamping device. The mandrel is rotated BY HAND without jerks
– from the initial position (Figure 15) to the final position (Figure 16) and back;
– as above for the second time;
– from the initial position to the final position.
If a sample breaks during rotation where it is fixed to the mandrel or the clamping device, this does not constitute a failure and the test is repeated on a fresh sample. If a sample breaks at any other place, the test has failed.
After this preconditioning, a sheet of metal foil, 0,035 mm ± 0,005 mm thick, at least 200 mm long, is placed along the surface of the sample, hanging down on each side of the mandrel (see Figure 16). The surface of the foil in contact with the sample shall be conductive, not oxidised or otherwise insulated. The foil is positioned so that its edges are not less than 18 mm from the edges of the sample (see Figure 17). The foil is then tightened by two equal weights, one at each end, using appropriate clamping devices.
While the mandrel is in its final position, and within the 60 s following the final positioning, a dielectric strength test is applied between the mandrel and the metal foil in accordance with
10.4.2, using a test voltage of 1,5 times the value specified in Table 5 for REINFORCED INSULATION , but not less than 5 kV.
The entire test procedure is repeated on the other two samples.

 

 

Standard:Confirm to IEC60065:2014 clause 8.21, figure 14~16, IEC60950

Application:Insulation anti damage strength verification for non separable thin layer materials.

Test sample:Non separable thin layer material.

Feature:The position of 10°and 230°are set with mechanical limit,not only to ensure the accuracy of the test angle, but also to achieve a simple operation method; weight with a hanging ring, in case of a point is damaged because of too large pull force.

 

Parameters:

1,Weight of 50N*3pcs,can be combined to achieve 100N and 150N testing.

2,Number of test times:3 times.

3,Withstanding voltage tester(Optional).
