IEC 60112-2017 is an international standard used for evaluating the electrical breakdown of solid insulating materials, such as plastics and rubber. It provides a method to determine the comparative tracking index (CTI) which measures the resistance of these materials to electric current leakage under wet conditions.
Why is IEC 60112-2017 important?
Electrical breakdown and tracking can occur when contaminants, moisture, or minerals are present on the surface of insulating materials. This can result in short circuits, fires, or other failures in electrical devices and systems. IEC 60112-2017 helps manufacturers assess the safety and performance of their products by testing the resistance of insulating materials to electrical breakdown.
How does IEC 60112-2017 work?
The standard uses a test procedure that involves applying an increasing voltage to electrodes placed on the surface of the material while it is immersed in a specified conductive solution. The voltage is gradually increased until electrical breakdown occurs, causing irreversible damage to the material. The comparative tracking index (CTI) is then determined based on the voltage required for breakdown.
Benefits of using IEC 60112-2017
The use of this standard ensures that insulating materials meet specific safety requirements and can withstand the presence of contaminants or moisture. By testing materials according to IEC 60112-2017, manufacturers can identify potential weaknesses in their products and make improvements to enhance performance and reliability.
