An environmental test chamber is a specialized device that simulates natural or artificial environmental conditions, including temperature, humidity, air pressure, salt spray, and vibration, to assess a product’s performance, durability, and reliability. The core function of these chambers is to precisely control environmental parameters, replicating the conditions a product may encounter during actual use or in extreme scenarios. This enables manufacturers to evaluate a product’s reliability, stability, and lifespan. 

Common types of environmental chambers include constant temperature and humidity chambers, high-low temperature chambers, rapid temperature change chambers, thermal shock chambers, and salt spray chambers. These are widely used in product development, quality control, and certification testing.

 

Environmental chambers are designed to comply with international standards such as IEC 60068, MIL-STD-810, and GB/T 2423, ensuring the scientific accuracy and repeatability of test results. By simulating extreme conditions, these chambers help manufacturers identify design flaws, optimize material selections, and enhance product quality, ultimately reducing the risk of failures in real-world applications.

 

 

Environmental chambers are integral to various industries, where they serve critical functions in product quality validation, reliability testing, and compliance with industry standards. Below are key sectors where these chambers are extensively utilized:

 

Electronic products, such as circuit boards, chips, and displays, must maintain stable performance under diverse climatic conditions. Environmental chambers simulate high temperatures, low temperatures, and humid conditions to test the durability and reliability of electronic components. For instance, constant temperature and humidity chambers assess the insulation performance of electronics in high-humidity environments, while thermal shock chambers evaluate a product’s ability to withstand rapid temperature changes. These tests ensure that electronic devices remain functional in extreme climates or during prolonged use, minimizing the risk of failures.

Automotive components and new energy batteries, such as those used in electric vehicles, undergo rigorous testing to ensure safety and durability under extreme temperatures and humidity levels. For example, power batteries are subjected to cycling tests within a temperature range of -40°C to 85°C to verify their charge-discharge performance and lifespan. Environmental chambers replicate these extreme conditions, enabling manufacturers to optimize product designs and meet standards like ISO 16750. This ensures that automotive components and batteries perform reliably in harsh environments, enhancing vehicle safety and longevity.

In materials science, environmental chambers are used to evaluate the aging performance of metals, plastics, rubbers, and composites under conditions such as high humidity, salt spray, or low temperatures. For instance, salt spray chambers simulate marine environments to assess a material’s corrosion resistance, while constant temperature and humidity chambers test material stability in prolonged high-humidity conditions. These tests provide critical data for developing new materials and optimizing their performance, supporting advancements in industries ranging from construction to aerospace.

The performance of compact fluorescent lamps (CFLs) and light-emitting diodes (LEDs), including luminous flux, color temperature, and energy efficiency, is highly sensitive to environmental factors like temperature and humidity. High temperatures can accelerate LED chip degradation, while humid conditions may cause circuit board corrosion. LISUN’s constant temperature and humidity chambers, such as the LIS-150HC model, can simulate temperatures from -40°C to +150°C and humidity levels from 20% RH to 98% RH. These chambers enable precise testing of CFL and LED products under extreme conditions. For example, an LED manufacturer used the LIS-225HC chamber to test luminaires under high-temperature and high-humidity conditions (85°C/85% RH), identifying light degradation issues and optimizing heat dissipation designs to extend product lifespan.
