What is the IEC 60068-21 procedure?

The IEC 60068-21 procedure is a standardized test method used to assess the ability of electronic equipment to withstand severe climatic conditions. This procedure, also known as the Environmental Testing - Part 21, is defined by the International Electrotechnical Commission (IEC) and is widely recognized in the technical community.

The significance of the IEC 60068-21 procedure

The IEC 60068-21 procedure plays a crucial role in ensuring the reliability and durability of electronic devices. By subjecting them to various environmental stresses, this procedure enables manufacturers and designers to identify potential weaknesses in their products and make necessary improvements.

Through a series of well-defined tests, the IEC 60068-21 procedure evaluates the equipment's performance under extreme conditions such as temperature fluctuations, humidity levels, and mechanical stresses. These tests go beyond the standard operating parameters and simulate real-life scenarios that the equipment may encounter during transportation, storage, or operation.

The testing process

The IEC 60068-21 procedure consists of several stages, with each stage focusing on a different environmental factor. The most common tests carried out include:

Temperature Test: The equipment is subjected to both high and low temperatures to evaluate its performance and functionality within these extremes. It helps determine if the device can withstand overheating or freezing conditions without any adverse effects on its operation.

Humidity Test: This test measures the equipment's reaction to high humidity levels, which can cause condensation and moisture build-up. It ensures that the devices are adequately sealed and protected against water ingress, preventing internal damage.

Mechanical Test: In this test, the equipment is subjected to various vibrations and shocks that simulate transportation or handling. It assesses the robustness of the device's mechanical components and ensures they can withstand rough usage.

Benefits and applications

The IEC 60068-21 procedure provides numerous benefits to manufacturers, end-users, and regulatory bodies alike. For manufacturers, it helps in product development by identifying weaknesses and guiding improvements. End-users benefit from knowing that the devices they purchase have passed rigorous testing and are reliable under challenging conditions.

Regulatory bodies often require compliance with the IEC 60068-21 procedure for certain industries such as automotive, aerospace, and telecommunications. Adhering to these standards ensures consistent quality across different products and promotes safety, reliability, and compatibility within the industry.

In conclusion, the IEC 60068-21 procedure is a valuable tool that aids in the design, production, and assessment of electronic equipment. By subjecting devices to extreme environmental conditions, this procedure ensures their ability to withstand real-life scenarios and enhances overall reliability.
