IEC 60068-2-30 Humidity and Damp Heat Environmental Stress Testing of Batteries
The International Electrotechnical Commission (IEC) standard IEC 60068-2-30 defines the methods for determining the resistance to humidity and damp heat exposure. This testing is crucial in assessing how batteries, particularly those used in automotive, aerospace, and consumer electronics sectors, perform under extreme environmental conditions.
The primary objective of this test is to ensure that batteries are reliable and safe when exposed to high-humidity environments and temperatures that can exceed 85°C for a prolonged period. This type of testing simulates the real-world conditions where batteries may be subjected to these stresses during use, storage, or transportation.
The battery specimens undergo rigorous environmental stress exposure in controlled laboratory settings. The test parameters include humidity levels ranging from 93% RH at room temperature to 85°C under 85% RH for a specified duration. This ensures that the batteries are subjected to stresses that they may encounter during their lifecycle.
Preparation of specimens involves ensuring that they meet the relevant IEC standards and guidelines, which specify the correct method of mounting, the type of battery, and its operational conditions. The testing apparatus is designed to maintain precise control over temperature, humidity, and exposure time. This ensures that the test results are accurate and repeatable.
The test procedure involves placing the battery specimens into a chamber where they are subjected to the specified environmental stress for the required duration. After the exposure period, the batteries undergo thorough inspection and evaluation to check for any signs of degradation or failure. The acceptance criteria include specific limits on changes in performance parameters such as voltage, internal resistance, and capacity.
Understanding these standards is essential for quality managers, compliance officers, R&D engineers, and procurement teams working with battery manufacturers or suppliers. Compliance with IEC 60068-2-30 ensures that products meet the highest safety and performance standards, enhancing reliability and customer confidence.
The importance of this testing cannot be overstated, especially in sectors where battery failure can lead to significant consequences such as loss of power or even safety hazards. By adhering to these stringent environmental stress tests, manufacturers can ensure their batteries are robust enough to withstand the rigors of real-world conditions.
Industry Applications
- Automotive industry: Ensuring battery reliability in various climates and environments.
- Aerospace sector: Testing for durability and performance under extreme conditions.

International Acceptance and Recognition
The IEC 60068-2-30 standard is widely recognized and accepted across the global market. It is a key requirement for compliance with international regulations related to battery safety and performance standards.
Countries like the United States, Europe, China, Japan, and others have adopted this standard as part of their national testing protocols. This ensures that products meeting these standards are accepted in multiple markets without additional certification requirements. The widespread acceptance also helps manufacturers navigate global trade more efficiently by ensuring their products meet a single set of internationally recognized criteria.
Companies involved in the development, production, and distribution of batteries find it advantageous to comply with this standard as it enhances product reliability and safety, thereby improving market confidence and increasing sales potential. The standard is not only a technical specification but also a symbol of quality assurance that adds value to products in competitive markets.
