Singkat: Discover the IEC 61558 Figure 6 Mandrel Test, designed to evaluate the mechanical withstanding of insulating materials in thin sheet layers. This essential test ensures compliance with IEC standards, verifying insulation strength for safety in IT and audio equipment.

Fitur Produk terkait:

Tests mechanical withstanding of thin sheet insulating materials as per IEC 61558-1-Fig6.
Ensures compliance with IEC60950 and IEC60065-1 safety standards.
Includes a mandrel rotated forwards and backwards three times for 230°.
Applies dielectric strength test voltage post-rotation for 1 minute.
Supports test voltages of at least 5 kV or higher as per standards.
Detects flashover or breakdown during the dielectric strength test.
Requires three separate test specimens of thin sheets 70 mm in width.
Ideal for verifying insulation anti-damage strength in non-separable layers.

FAQ:

What standards does the IEC 61558 Figure 6 Mandrel Test comply with?

The test complies with IEC60950 for IT equipment safety, IEC60065-1 for audio/video apparatus safety, and IEC61558-1-Fig6 for insulating materials.
How is the dielectric strength test voltage determined?

The test voltage is at least 5 kV or the applicable voltage from Clause 18.3 multiplied by 1.35 for non-separable layers, or 1.25 for fewer layers, whichever is greater.
What happens if the specimen breaks during the test?

If the specimen breaks at the clamping device, the test is repeated. If it breaks elsewhere, the test is not fulfilled.
