IEC60811-3-1 High Temperature Indentation Device Equipped With 30 PCS Weights

IEC 60811-3-1 clause 8.2.3 Position of the test piece in the test apparatus
The indentation device shall be the same as specified in Sub-clause 8.1.3 and shown in Figure 1.
The strips shall be supported by a metal pin or tube, which may be halved in the direction of its axis to make a more stable support.
The radius of the pin or tube shall be approximately equal to half the inner diameter of the test piece.                      Cable Testing Equipment
The apparatus, the strip and the supporting pin (tube) shall be arranged so that the pin supports the strip and the blade is pressed against the outer surface of the test piece.                            Cable Testing Equipment
The force shall be applied in a direction perpendicular to the axis of the pin (or of the cable when a whole cable piece is used) and the blade shall also be perpendicular to the axis of the pin or tube (or of the cable when a whole cable is used).

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 clause 8 and 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
