OEM Thermal Shock Test Chambers Meets Military Standard 202, Method 107 Standards

1. Product Name and Purpose

2. Product Features

• Robust and Rugged Chamber Construction
  • The chamber is constructed with heavy-duty, high-strength materials that can endure the punishing forces and stresses associated with military-standard testing. The walls are fabricated from thick, heat-treated steel alloy, fortified with advanced thermal insulation layers to minimize heat leakage and ensure precise temperature control. The door is engineered with a redundant sealing mechanism and a reinforced viewing window, allowing operators to monitor the testing process without compromising the chamber's integrity. The interior is designed with a modular layout, facilitating the accommodation of variously sized and shaped military components, and equipped with adjustable mounting fixtures and racks for secure and uniform sample positioning.
• Precision Temperature Control and Cycling System
  • Temperature Range and Cycling Capability: Capable of achieving an extensive temperature range, typically from -75°C to +150°C. The system can execute rapid and precise temperature cycling between the hot and cold zones, with a transition time as brief as a few seconds. This is crucial for mimicking the abrupt temperature changes that military equipment may experience in the field, such as during rapid ascents or descents in aircraft or exposure to extreme environmental shifts. The temperature control is accurate to within ±0.2°C, providing the level of precision required for reliable and repeatable test results.
  • Programmable Temperature Profiles: The chamber's control system allows for the creation and execution of complex, custom temperature profiles. Operators can define specific temperature levels, dwell times in each zone, and the sequence and number of thermal shock cycles to replicate a wide range of real-world military operational scenarios. This flexibility enables comprehensive testing of components under different mission-critical conditions.
• Intuitive Control Panel and Data Acquisition Interface
  • The control panel is designed for ease of use by military technicians and engineers. It features a clear and intuitive interface that enables effortless setting and adjustment of all test parameters, including temperature, cycling times, and sample identification. The panel also provides real-time displays of the current temperature in both zones, the status of the testing process, and any alarms or warnings. The chamber is integrated with a sophisticated data acquisition system that records all relevant test data. This includes detailed temperature histories, cycle counts, and any observable changes in the physical, electrical, or mechanical properties of the tested components. The data can be stored in a secure, encrypted format in the chamber's built-in memory or exported to external military-grade storage devices for in-depth analysis and reporting. The system can also generate comprehensive test reports in various standardized military formats.
• Enhanced Safety and Security Features
  • To ensure the safety of operators and the protection of sensitive military test samples and the chamber itself, a comprehensive suite of safety and security features is incorporated. These include multiple layers of over-temperature and over-current protection, emergency stop buttons with redundant circuitry, and advanced alarms for any abnormal temperature fluctuations, equipment malfunctions, or security breaches. The chamber is also equipped with biometric access controls and intrusion detection systems to prevent unauthorized access and safeguard classified testing activities. Additionally, it has a self-contained fire suppression system and proper ventilation and exhaust mechanisms to handle any potentially hazardous gases or vapors that may be generated during testing.

3. Specific Parameters

• Temperature Range and Accuracy
  • The -75°C to +150°C temperature range with ±0.2°C accuracy offers an extensive and precise testing envelope. Military components often have strict temperature tolerance requirements due to their exposure to diverse and harsh environments. For example, electronic components in a fighter jet's avionics suite must function flawlessly across a wide temperature spectrum. The accurate temperature control ensures that the test conditions precisely match the demands of Military Standard 202, Method 107, allowing for a meticulous assessment of component performance and reliability.
• Thermal Shock Cycle Parameters
  • The chamber can be programmed to perform a highly customizable number of thermal shock cycles, ranging from a few dozen to several thousand, depending on the specific military equipment's requirements and expected service life. The dwell time in each temperature zone can be adjusted from milliseconds to hours, enabling the simulation of a vast array of mission profiles. For instance, a missile guidance system may need to withstand short, intense thermal shock cycles during launch and flight, while a communication relay station might experience longer, more gradual temperature changes over an extended period.
• Testing Volume and Payload Capacity
  • The chamber offers a flexible testing volume, typically ranging from 3 m³ to 15 m³, to accommodate a wide variety of military components and assemblies, from small circuit boards to large weaponry subsystems. The payload capacity is designed to handle heavy and bulky items, with a maximum capacity of up to several tons, ensuring that even the most substantial military hardware can be effectively tested.
• Data Sampling Frequency and Resolution
