IEC EN 60455-2 Test Methods for Resin Based Reactive Compounds Used for Electrical Insulation

EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of IEC EN 60455-2 testing. This part of IEC EN 60455 specifies test methods to be used for testing resin-based reactive compounds, their constituents and cured compounds for electrical insulation.

Unless otherwise specified in the relevant specification standard or test method, all tests must be performed in atmospheric conditions within the temperature range of 21°C to 29°C and relative humidity of 45% to 70%.

The standard covers the following test methods:

• Gel time: This test determines the time it takes for the resin to gel at a given temperature. It is important as it helps determine the curing time required for the resin.
• Viscosity: This test measures the viscosity of the resin at a given temperature. It is important as it helps determine the flow properties of the resin.
• Density: This test determines the density of the resin. It is important as it helps determine the weight of the insulation material.
• Tensile strength and elongation at break: These tests determine the mechanical properties of the resin. Tensile strength measures the maximum stress the material can withstand before breaking, while elongation at break measures the amount of deformation the material can undergo before breaking.
• Thermal stability: This test measures the resin's ability to withstand high temperatures without degradation. It is important as it helps determine the suitability of the material for use in high temperature environments.
• Dielectric strength: This test determines the electrical insulating properties of the resin. It measures the voltage required to degrade the insulating properties of the material.
• Tracing and erosion resistance: These tests determine the resin's ability to resist the effects of electrical tracking and erosion caused by the presence of contaminants on the surface of the material.

By following the test methods outlined in IEC EN 60455-2, manufacturers can ensure that resin-based reactive compounds meet the required standards for electrical insulation.
