IEC 60068 2 2 Dry Heat Environmental Test
The IEC 60068-2-2 dry heat environmental test is a critical step in the evaluation of electronic products' resistance to high temperatures. This standard is part of the broader series designed for electrical, electronic, and mechanical products subjected to various climatic stresses. The primary goal of this test is to determine whether an electronic product can withstand the effects of continuous exposure to dry heat without sustaining damage that could affect its performance or reliability.
Electrical devices operating in harsh environments often face extreme temperatures that can degrade their components over time. By subjecting these products to controlled high-temperature conditions, engineers and quality managers can identify potential weaknesses early on, ensuring that the final product meets both current standards and future needs. The test is particularly useful for verifying the durability of circuit boards, connectors, and other temperature-sensitive parts.
The dry heat test is conducted in a temperature-controlled chamber where the specimen is exposed to a specified temperature range for a defined duration. Typically, this involves maintaining temperatures between 70°C and 85°C (158°F - 185°F) depending on specific requirements set by the standard or client specifications.
During the test, it's crucial that the specimen is prepared correctly to ensure accurate results. This includes ensuring clean surfaces free from contaminants which could interfere with the test outcome. Additionally, any protective coatings must be removed if they are not intended for the final product use. The apparatus used in this testing process typically consists of an oven or a climate chamber capable of maintaining precise temperature settings.
The acceptance criteria for passing this test vary based on the type and function of the electronic component being tested; however, generally speaking, successful completion means that after exposure to these conditions over the specified period, there should be no visible signs of damage such as cracks or discoloration. Furthermore, functionality tests may also need to pass post-test checks.
Understanding how this test fits into broader product development is essential for companies looking to ensure their products meet regulatory requirements and perform reliably under expected conditions throughout their lifecycle. As part of an integrated quality assurance program, it helps prevent costly recalls later down the line by identifying issues early on during design stages or manufacturing processes.

Benefits
The IEC 60068-2-2 dry heat environmental test offers numerous advantages to manufacturers and suppliers of electronic products. One significant benefit is the ability to identify potential weaknesses early in the development process, allowing for corrective actions before mass production begins. This not only saves time but also reduces costs associated with product recalls or warranty claims.
Another advantage lies in its contribution towards meeting regulatory requirements. Many countries have regulations governing the safety and quality of electrical products sold within their borders. Compliance with standards like IEC 60068-2-2 can help companies avoid penalties, improve brand reputation, and gain market access more easily.
Moreover, successful completion of this test demonstrates a commitment to maintaining high-quality standards throughout the supply chain, which is increasingly important as global competition intensifies. It also enhances customer trust by providing assurance that purchased products will perform reliably under expected operating conditions.
Quality and Reliability Assurance
- Data logging of temperature and duration to ensure compliance with test parameters.
- Visual inspection for any visible signs of damage such as cracks or discoloration.
- Functional tests post-test checks to confirm the product retains its intended performance capabilities.
