AGREE Test Chamber

The Sanwood AGREE Test Chamber provides simultaneous application of temperature, humidity, and vibration stresses in a single integrated system. Designed to accelerate reliability testing and uncover failure mechanisms that single-stress testing may miss, this advanced chamber delivers realistic simulation of combined field environments for critical electronic and mechanical systems.

• •Engineered to meet rigorous test protocols including MIL-STD-810 (Method 514), RTCA DO-160 (Section 8), IEC 60068-2-50/53, and custom combined environment profiles.
• •Electrodynamic shaker system (customizable force ratings) seamlessly integrated with climatic chamber, minimizing test setup time and specimen handling.
• •Reproduces real-world stress interactions more accurately than sequential single-factor testing, providing higher confidence in product reliability.

The AGREE test chamber is a device to obtain combined temperature, humidity and vibration conditions in one chamber, for function evaluation for analogue electronics, aerospace products, auto mobile and communication products, etc. Following are main application fields:

• •Electronics: To test and evaluate functions and reliability of electric parts for mobile phones, laptops, and chipset, etc., under different environmental conditions.
• •Auto Mobile: To test function and evaluate durability and reliability of engine, brake, tyres, gears, control units, control panel, etc., by simulating different environmental conditions.
• •Aerospace: To test performance of meters, control systems, aerospace materials, spare parts etc., under extreme environmental conditions.
• •New Energy: To test varies of new energy products such as (solar panel, wind generators, etc.) in different environmental conditions, to evaluate function and reliability of the devices, and to increase the device lifespan and working efficiency.

Testing standards for AGREE test chamber are different according to specified industries or specified application.

• •MIL-STD-810: US military test standards, which is widely used in military and aerospace area. Multiple environmental test methods are included.
• •IEC 60068-2-30：Environmental testing - Part 2-30: Tests - Test Db: Damp heat, cyclic (12 h + 12 h cycle).
• •ISO 16750：Road vehicles — Environmental conditions and testing for electrical and electronic equipment.
• •ISO 2233：Packaging-Complete, filled transport packages and unit loads-conditioning for testing.
• •SAE J1211：Recommended Environmental Practices for Electronic Equipment Design.

The control system of the Sanwood test chamber adopts the world's leading software and hardware system to ensure that the test chamber operates under preset conditions, provide accurate and reliable experimental data, and help users achieve precise control and data collection of various experimental conditions.

• •Controller: It adopts the controller imported from South Korea Sanwon and the self-developed control system, which can be equipped with Siemens control system and equipped with RS232, RS485 and Ethernet communication ports.
• •Programmable control: It supports setting experimental programs, such as heating, cooling, constant temperature time, etc., and can execute multiple program settings, and supports advance reservation startup function.
• •Multiple languages optional: English, Korean, Russian, Chinese and Japanese.
• •Remote monitoring: Using network remote technology to achieve remote control, the test chamber can be monitored at any time, and the current data can be viewed through the user's PC and mobile phone, which improves the convenience of testing.

The specific control system of the test chamber will vary depending on the model. Please read the "Sanwood Environmental Test Chamber Manual" carefully before use and comply with the safety operating procedures.

The refrigeration system of the test chamber is a complex and important system. The stability of the refrigeration system is crucial to the accuracy and reliability of the test results.

• •Sanwood Technology has developed a refrigerant hot gas defrosting technology, which effectively melts the frost on the evaporator by injecting high-temperature and high-pressure refrigerant steam into the heat exchanger in the test chamber. This not only ensures that the evaporator does not frost, but also greatly reduces the energy consumption of the equipment.
• •The refrigeration unit adopts an internationally renowned brand.
• •Optimize the layout of the refrigeration system, and adopt VRF (refrigerant flow control) technology based on the PID cold end output principle to achieve low-temperature energy-saving operation, which can reduce energy consumption by 30% under low-temperature conditions.
• •The refrigeration system adopts a modular design, with low failure rate, few welding points, high refrigeration efficiency, good reliability, simple maintenance, and low maintenance cost.
