Vibration Climate Test Chamber Meeting ASTM D4169-16 Standard For Electrical Industry

1. Product Name and Purpose

2. Product Features

• Robust and Modular Chamber Construction
  • The climate chamber is built with a heavy-duty steel frame that provides exceptional rigidity and stability. The frame is coated with a corrosion-resistant finish to enhance its longevity. The chamber walls are made of high-quality insulation materials, which minimize heat transfer and maintain precise temperature and humidity levels. The insulation is carefully selected to withstand the rigors of continuous testing and prevent any external factors from interfering with the internal test environment. The chamber is also equipped with a hermetic door seal, ensuring a leak-free enclosure and consistent test conditions. The modular design allows for easy customization and integration of different components, such as the vibration test system.
• Precision Temperature and Humidity Control System
  • The chamber features a highly accurate temperature and humidity control system. It can maintain a wide temperature range, from -40°C to +180°C, with an accuracy of ±0.5°C. The humidity control range extends from 10% to 98% relative humidity, with an accuracy of ±2% RH. The system utilizes advanced refrigeration units, electric heaters, humidifiers, and dehumidifiers to achieve and maintain the desired environmental conditions. Temperature and humidity sensors are strategically placed within the chamber to provide real-time feedback, enabling the control system to make rapid and precise adjustments.
• High-Performance Vibration System
  • The integrated vibration test system is capable of generating a wide range of vibration frequencies and amplitudes. The frequency range can span from 2 Hz to 2000 Hz, allowing for the simulation of various real-world vibration sources, such as machinery operation, transportation vibrations, and seismic activity. The vibration amplitude can be adjusted from a few micrometers to several centimeters, depending on the test requirements. The vibration system is equipped with a rigid vibration table and a high-torque motor, ensuring uniform and stable vibration transmission. It also features advanced control algorithms that enable the creation of complex vibration profiles, including random vibrations, sine waves, and shock pulses.
• Synchronized Control and Data Acquisition
  • The system is equipped with a sophisticated control panel that allows for seamless synchronization of vibration and climatic parameters. Operators can precisely program the sequence and intensity of vibrations, temperature changes, and humidity levels, creating custom test profiles that meet ASTM D4169-16 requirements. The control panel also provides real-time monitoring of all test parameters, including temperature, humidity, vibration frequency, amplitude, and sample status. The data acquisition system records detailed information about the test, such as temperature and humidity profiles, vibration waveforms, and any changes in the physical properties of the electrical sample. The acquired data can be stored in a variety of formats and analyzed using specialized software to generate comprehensive test reports.
• Compliance with ASTM D4169-16 Standard
  • The equipment is specifically calibrated and programmed to perform tests in strict accordance with ASTM D4169-16. It can replicate the various vibration profiles, temperature and humidity cycles, and test durations specified in the standard. This ensures that the test results are valid and comparable, allowing manufacturers to make informed decisions about product design, material selection, and quality control. The chamber also provides a means for documenting compliance with the standard, which is essential for product acceptance in the electrical industry.

3. Specific Parameters

• Vibration Frequency Range
  • As mentioned, the vibration frequency range of 2 Hz to 2000 Hz covers a wide spectrum of vibrations that electrical products may experience. Low-frequency vibrations can affect the stability and alignment of larger components, while high-frequency vibrations can cause fatigue and failure in smaller, more delicate parts. Testing across this frequency range ensures a comprehensive evaluation of a product's performance under different vibration scenarios.
• Vibration Amplitude Range
  • The vibration amplitude can be adjusted from a few micrometers to several centimeters. This flexibility allows for the simulation of both mild and severe vibration conditions. For example, a small electronic circuit board may require a relatively small vibration amplitude to test its resistance to the vibrations of a delivery van, while a large industrial electrical enclosure may need to be tested at a higher amplitude to simulate the rough handling it might receive during shipping.
• Temperature Cycling Range
  • The chamber can perform temperature cycling within the range of -40°C to +180°C. This wide temperature range is crucial for testing electrical products that may be used in extreme climates or industrial environments. For instance, components used in outdoor power generation equipment may need to withstand high temperatures, while those in cold storage facilities or arctic applications may face extremely low temperatures. Temperature cycling also helps to evaluate the thermal expansion and contraction characteristics of products and their potential impact on performance and reliability.
• Humidity Cycling Range
  • The humidity cycling range of 10% to 98% relative humidity enables the assessment of product performance under different moisture levels. High humidity can cause condensation, corrosion, and other moisture-relat
