IEC60950-1 Annex AA Mandrel Test Device With Three 50N weights


IEC60950-1 Annex AA

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 AA.1) as shown in Figure AA.2.

A downward force of 150 N ± 10 N is applied to the free end of the sample (see Figure AA.3), using an appropriate clamping device. The mandrel is rotated
− from the initial position (Figure AA.2) to the final position (Figure AA.3) and back;
− as above for a second time;
− from the initial position to the final position. Audio Video Test Equipment
If a sample breaks during rotation where it is fixed to the mandrel or to the clamping device, this does not constitute a failure. If a sample breaks at any other place, the test has failed.
After the above test, 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 AA.3). The surface of the foil in contact with the sample shall be conductive, not oxidized or otherwise insulated. The foil is positioned so that its edges are not less than18 mm from the edges of the sample (see Figure AA.4). The foil is then tightened by two equal weights, one at each end, using appropriate clamping devices. Audio Video Test Equipment


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. Audio Video Test Equipment

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.
