IEC60811-3-1 High Temperature Indentation Device With 90° And 120° Sector-Shaped Profile​

IEC 60811-3-1 clause 8.1.3 Position of each test piece in the test apparatus
The indentation device is shown in Figure 1, and consists of a rectangular blade with an edge 0.70 ± 0.01 mm wide, which can be pressed against the test piece. Each test piece shall be placed in the position shown in Figure 1. Flat cords without sheaths shall be laid on their flat side. Test pieces having a small diameter shall be fixed on the support in such a manner that they do not curve under the pressure of the blade. Test pieces of sector-shaped cores shall be placed on a support provided with a fitting sector-shaped profile as shown in Figure 1. The force shall be applied in a direction perpendicular to the axis of the core; the blade shall also be perpendicular to the axis of the core.

Standard:

IEC 60811-508 Electric and optical fibre cables — Test methods for non-metallic materials - Part 508: Mechanical tests — Pressure test at high temperature for insulation and sheaths, IEC 60811-3-1 figure1. Cable Testing Equipment

Application:

For PVC insulated and sheathed wire and cable products, measure resistance to thermal deformation of PVC insulated and sheathed under the action of thermal and mechanical load, the insulation wire to be measured can be round, fan-shaped and parallel cord, the sheathed to be measured can be round or flat. It is not recommended to use this test method when the thickness of the test sample (Insulation or sheath) less than 0.4MM. Cable Testing Equipment

Test sample:

PVC insulated and sheathed wire and cable products, the material of pin-insulating sleeves
