IEC 60068: Environmental Testing of Electronic Equipment

IEC 60068: Environmental Testing of Electronic Equipment



In today's fast-paced world, electronic equipment is an integral part of our daily lives. From smartphones to computers, these devices play a crucial role in how we communicate, work, and stay entertained. However, as electronic equipment becomes more advanced and complex, it is also more susceptible to environmental factors that can impact its performance and reliability. This is where environmental testing comes into play.


Environmental testing is a critical aspect of ensuring the quality and reliability of electronic equipment. It involves subjecting the equipment to a series of tests that simulate the conditions that it may encounter in its intended environment. One of the most widely recognized standards for environmental testing of electronic equipment is the IEC 60068.


IEC 60068: Overview

IEC 60068 is a series of standards published by the International Electrotechnical Commission (IEC) that outline the various environmental tests that electronic equipment must undergo to ensure its reliability and performance. The standard covers a wide range of environmental factors, including temperature, humidity, vibration, and shock.


The IEC 60068 standard is divided into different parts, each focusing on a specific aspect of environmental testing. Some of the key parts of the standard include:


- Part 2-1: Tests - Test A: Cold

- Part 2-2: Tests - Test B: Dry heat

- Part 2-3: Tests - Test Cab: Damp heat, steady-state

- Part 2-27: Tests - Test Ea and guidance: Shock

- Part 2-30: Tests - Test Db: Damp heat, cyclic (12 h + 12 h cycle)

- Part 2-41: Tests - Test E: Shock

- Part 2-47: Tests - Test Ga: Sine vibration

- Part 2-78: Tests - Test Cab: Damp heat, steady-state, accelerated

- Part 3: Background information documentation

- Part 4: Guidance on the application of the standard


Each part of the IEC 60068 standard provides detailed guidelines on how to conduct environmental tests on electronic equipment and interpret the results. By following these standards, manufacturers can ensure that their products are robust and reliable in a variety of environmental conditions.


Importance of Environmental Testing

Environmental testing is crucial for ensuring the reliability and performance of electronic equipment. By subjecting the equipment to a series of tests that simulate real-world environmental conditions, manufacturers can identify potential weaknesses and design flaws before the products are released to the market.


One of the key benefits of environmental testing is that it helps manufacturers predict how their products will perform in the field. For example, by subjecting a smartphone to temperature and humidity tests, manufacturers can determine whether the device will operate reliably in hot and humid environments. Similarly, vibration and shock tests can help identify potential issues with the device's structural integrity and durability.


In addition to improving product reliability, environmental testing can also have financial benefits for manufacturers. By identifying and addressing design flaws early in the development process, manufacturers can avoid costly product recalls and repairs down the line. This not only helps protect the manufacturer's reputation but also ensures customer satisfaction and loyalty.


Overall, environmental testing is a critical step in the product development process that can help manufacturers deliver high-quality, reliable electronic equipment to the market.



In conclusion, the IEC 60068 standard is an essential tool for manufacturers looking to ensure the quality and reliability of their electronic equipment. By following the guidelines outlined in the standard, manufacturers can subject their products to a series of environmental tests that simulate real-world conditions. This allows them to identify potential weaknesses and design flaws early in the development process, ultimately leading to more reliable and durable products.


Environmental testing plays a crucial role in ensuring the performance and reliability of electronic equipment in a variety of environmental conditions. By conducting these tests, manufacturers can improve product quality, reduce the risk of defects, and ultimately deliver better products to the market. As technology continues to advance, the importance of environmental testing will only grow, making standards like the IEC 60068 an indispensable tool for manufacturers worldwide.
