TestEQ delivered a batch of environmental test chambers to the Dongguan Product Quality Supervision and Inspection Center (Dongguan Quality Inspection Laboratory) and completed commissioning. The systems are used for product reliability verification, quality inspection and certification testing.
Customer background
The Dongguan Product Quality Supervision and Inspection Center is a national-level quality inspection institution in South China. It verifies product compliance across electronics, automotive components, industrial materials and consumer products, and its results support certification and market access.
Need and test conditions
As an accredited testing organization, the laboratory needed equipment with high temperature accuracy, stable humidity control and reliable long-term operation, used repeatedly for certification work. Test conditions span a wide range, and results have to be reproducible from run to run for the data to stand up in reports.
Configuration
The delivered solution combined several environmental simulation systems:
- Temperature and humidity test chambers
- Programmable environmental simulation systems
- Precision control and monitoring units
- Data acquisition and remote logging interfaces
The chambers support conditions from -70°C to +150°C with humidity control from 20% to 98% RH. Airflow design and PID multi-loop control are used to hold stable thermal response and spatial uniformity over long test cycles. The programming system allows multi-step temperature-humidity cycles, soak, ramp and dwell time settings, real-time monitoring and data export for certification reports.
The systems are designed for continuous operation and for the standards the laboratory works to, including ISO 17025 laboratory requirements, IEC environmental testing standards and GB/T reliability test protocols. Related applications include IEC 60068 and MIL-STD environmental testing and reliability qualification testing.
Outcome
The project was completed with on-site engineering support: mechanical installation and system setup, calibration of temperature and humidity accuracy, functional validation under load, and operator training for laboratory staff. The systems passed performance verification and were integrated into the laboratory testing workflow.
Applications the installed systems support include product reliability validation in R&D, environmental stress screening, accelerated aging tests, material stability analysis and certification and compliance testing.
