Tri-Environmental Test Chamber (Vibration-Only Mode Capable)

Overview

The Tri-Environmental Test Chamber (Vibration-Only Mode Capable) is an integrated reliability testing system engineered for concurrent or independent application of temperature stress (high/low), humidity (optional configuration), and mechanical vibration. Designed in accordance with fundamental principles of accelerated life testing and HALT/HASS methodologies, this chamber enables controlled simulation of real-world operational and transport environments where thermal cycling and dynamic mechanical loading co-occur. Its modular architecture supports both tri-combined stress testing—simultaneous temperature change and broadband random vibration—and standalone high-fidelity vibration testing across defined frequency and displacement ranges. The system complies with core structural and safety requirements outlined in IEC 60068-2-6 (vibration), IEC 60068-2-1 (cold), IEC 60068-2-2 (dry heat), and ISO 16750-4 (road vehicle environmental conditions), making it suitable for pre-compliance screening in electronics, automotive components, aerospace subsystems, and industrial control hardware.

Key Features

• Triple-stress integration capability: Simultaneous temperature conditioning (−70 °C to +180 °C standard range) and electrodynamic vibration (5–2000 Hz, 50 g peak acceleration, 25 mm p-p displacement)
• Dedicated vibration-only operational mode: Bypasses thermal chambers to enable high-reproducibility sinusoidal/random vibration testing per MIL-STD-810H, ASTM D999, and GB/T 2423.10
• Stainless steel inner chamber with reinforced mounting interface for 50–100 kg payload capacity; integrated slip table with low-transmissibility isolation mounts
• Programmable controller with dual-channel PID regulation for temperature and vibration profile synchronization
• Real-time data logging at up to 10 kHz sampling rate; USB and Ethernet interfaces for remote monitoring and control
• Compliant with CE machinery directive (2006/42/EC) and RoHS 2 (2011/65/EU); optional upgrade for ATEX Zone 2/22 certification

Sample Compatibility & Compliance

The chamber accommodates test specimens up to 600 × 600 × 600 mm (W × D × H) with standardized 120 mm-diameter vibration table mounting holes (M8 thread pattern). It supports PCB assemblies, power modules, sensor housings, connector subassemblies, and small-scale embedded controllers. All thermal and vibrational profiles are traceable to NIST-traceable reference standards via onboard calibration ports. System validation documentation includes IQ/OQ protocols aligned with GLP and ISO/IEC 17025 requirements. Full audit trails—including operator ID, parameter changes, and alarm events—are retained for FDA 21 CFR Part 11–compliant environments when paired with optional software license.

Software & Data Management

Supro’s proprietary TestMaster™ v4.2 software provides intuitive waveform definition (sine, random, shock, swept-sine), real-time FFT spectrum analysis, and automated pass/fail evaluation against user-defined thresholds. Data export supports CSV, MATLAB (.mat), and Universal File Format (UFF 58). The software includes built-in report generators compliant with ISO 17025 Annex A.2 and supports digital signature workflows for electronic records retention. Remote access is enabled via TLS 1.2–secured web interface, supporting role-based permissions (administrator, technician, reviewer) and configurable email/SNMP alerts for test completion or fault conditions.

Applications

• Qualification testing of avionics modules under combined thermal-vibrational stress per DO-160 Section 20
• Pre-shipping validation of automotive ECUs subjected to road-simulated vibration and under-hood temperature extremes
• Failure mode identification in MEMS accelerometers during thermal shock + resonant excitation
• Reliability growth testing of medical device enclosures (IEC 60601-1 Clause 10.2.2)
• Material fatigue assessment of solder joints using temperature-cycled random vibration per IPC-9701A
• Component-level HALT screening for consumer electronics OEMs targeting IEC 62380 failure prediction models

FAQ

Can the chamber operate vibration-only without engaging temperature control?
Yes. The system features a dedicated “Vibration Standalone” mode that deactivates refrigeration/heating circuits while maintaining full vibration controller functionality and compliance with ISO 10816-1 vibration severity classifications.
Is third-party calibration support available?
Supro Instruments maintains ISO/IEC 17025-accredited calibration laboratories in Shanghai and Suzhou; on-site calibration and uncertainty reporting (k=2) are available globally upon request.
What is the maximum payload for combined temperature–vibration testing?
For simultaneous operation, the recommended maximum payload is 30 kg to ensure thermal uniformity (±2 °C) and vibration fidelity (±0.5 dB spectral flatness) across the specified frequency band.
Does the system meet MIL-STD-810G/H requirements?
The chamber satisfies Method 514.7 (vibration) and Method 501.6/502.6 (temperature) when configured with optional humidity control and calibrated transducers; full compliance verification requires customer-specific test plan alignment.
Are spare parts and service contracts available outside China?
Yes. Supro maintains regional technical support hubs in Germany, Singapore, and the United States, with 48-hour response SLAs for critical spares and annual preventive maintenance contracts including firmware updates and performance verification.
