What is IEC 60085-6:2019 ?

IEC 60085-6:2019 is an essential standard for anyone involved in the design, manufacturing, and testing of electrical equipment. The purpose of this article is to provide a clear and concise explanation of the key aspects of this standard.

Understanding Thermal Endurance

When it comes to electrical equipment, thermal endurance is a critical factor that must be taken into account. IEC 60085-6:2019 provides guidelines for evaluating and classifying the thermal properties of electrical insulation systems, which are used to separate electrical conductors from each other.

The Importance of Thermal Evaluation

Thermal evaluation is crucial in ensuring the safety and reliability of electrical devices. If the insulation on an electrical device is not able to withstand the heat generated by the device, it can cause a failure or even a fire.

IEC 60085-6:2019 provides a framework for evaluating the thermal properties of electrical insulation systems and ensuring that they are suitable for the specific application. The standard defines the different types of thermal endurance tests that can be used to evaluate the properties of electrical insulation, such as the ability to withstand a specific temperature for a certain amount of time.

The Tests and Classes

IEC 60085-6:2019 defines several classes of thermal endurance tests that can be used to evaluate the properties of electrical insulation systems. These classes are:

* Type I: a thermal test that simulates the exposure of the insulation to a high temperature for a short period of time.

* Type II: a thermal test that simulates the exposure of the insulation to a high temperature for a longer period of time.

* Type III: a thermal test that simulates the exposure of the insulation to a high temperature for a longer period of time, with the temperature being gradually increased.

Each of these tests is designed to evaluate a different aspect of the thermal properties of the electrical insulation system. For example, Type I is used to evaluate the short-term thermal resistance of the system, while Type II is used to evaluate the long-term thermal resistance of the system.

Conclusion

IEC 60085-6:2019 is an essential standard that provides guidelines and requirements for the thermal evaluation and classification of electrical insulation systems used in electrical equipment. By defining the different types of thermal endurance tests and classes, this standard ensures that the thermal properties of electrical insulation systems are suitable for the specific application.

In conclusion, IEC 60085-6:2019 is a crucial standard that should be followed when designing, manufacturing, and testing electrical equipment. By understanding the thermal properties of electrical insulation systems and ensuring that they are suitable for the specific application, this standard helps to ensure the safety and reliability of electrical devices.
