What is IEC 60068 55 ?

IEC 60068-55 is an essential standard for ensuring the reliability and performance of electronic and electrical equipment in severe environmental conditions. The standard defines a range of test methods and procedures to assess the resistance and durability of products, ensuring their reliability and safety in various operating environments.

Key Requirements and Tests in IEC 60068-55The primary purpose of IEC 60068-55 is to establish a common framework for manufacturers, engineers, and regulatory bodies to evaluate the resilience and functionality of electrical and electronic equipment. It covers a wide range of environmental conditions such as high and low temperatures, humidity, vibrations, shocks, and mechanical stresses.

To ensure compliance with the standard, manufacturers must perform a series of tests, which are designed to simulate real-world environments. These tests include:

Electrical Discharge (ED) Test: This test evaluates the equipment's resistance to electrical discharge from sources such as voltage spikes, electrostatic discharge, and voltage overload.

Electrical Over-current (IEC 60068-55) Test: This test measures the equipment's resistance to electrical currents, ensuring it can withstand the maximum current that the equipment is designed to handle.

Short-circuit Test: This test assesses the equipment's resistance to short circuits, which can cause equipment to overheat and potentially fail.

Voltage Test: This test evaluates the equipment's resistance to voltage surges, which can cause equipment to malfunction or fail.

Temperature Test: This test measures the equipment's resistance to extreme temperatures, such as high and low temperatures, which can cause equipment to degrade or fail.

Humidity Test: This test evaluates the equipment's resistance to humidity, which can cause equipment to become corroded or fail.

Vibration Test: This test evaluates the equipment's resistance to vibration, which can cause equipment to become damaged or fail.

Shock Test: This test evaluates the equipment's resistance to shock, which can cause equipment to become damaged or fail.

By subjecting the equipment to these tests, manufacturers can ensure that their products meet the standard's requirements for performance and reliability in severe environmental conditions.

ConclusionIEC 60068-55 is an essential standard for ensuring the reliability and performance of electronic and electrical equipment in severe environmental conditions. By subjecting the equipment to a series of tests that simulate real-world environments, manufacturers can ensure that their products meet the standard's requirements for performance and reliability.
