Electronic and Electrlcal Equipment Testing Center

02 / Reliability Testing Zone

ENVIRONMENTAL STRESS SCREENING CHAMBER

Features a spacious 12.6 m³ working capacity, ideal for large equipment or bulk product extreme climate screening. Precisely simulates extreme cryogenic, constant humidity, and alternating humidity environments — the core equipment for Environmental Stress Screening (ESS).

Capacity: 12.6 m³ Temperature: -65°C ~ +125°C Humidity: 20% ~ 98% RH Temp Change: >5°C/min

03 / Reliability Testing Zone

COMBINED ENVIRONMENTAL TEST CHAMBER

A true "tri-combined" environmental testing center. Integrates temperature, humidity stress, and dynamic vibration mechanics in a single chamber. Simultaneously applies multi-axis vibration during extreme temperature transitions to expose potential failure points under compound stress conditions.

Capacity: 2.73 m³ Temperature: -70°C ~ +150°C Humidity: 20% ~ 98% RH Temp Change: ≥10°C/min

04 / Environmental Testing Zone

HIGH / LOW TEMP RAPID CHANGE CHAMBER

Equipped with multiple high/low temperature humidity chambers and rapid temperature change testing equipment. Fully compliant with GJB and MIL-STD environmental testing standards.

Standard Tactical Testing Parameters

Non-operating Storage: High 70°C / Low -50°C
Full-function Operation: High 65°C / Low -40°C
Hot / Humid Operation: 60°C with 95% RH
Thermal Shock: Severe high-low temperature cycling

Range: -70°C ~ +150°C Temp Change: >5°C/min

05 / Mechanical Testing Zone

ELECTRODYNAMIC SHAKER

Supports both sinusoidal and random vibration testing, accurately simulating vibration environments of road, air, and rail transport as well as vehicle and airborne operational scenarios. Essential for structural strength verification and early assembly defect screening.

Max Acceleration: 980 m/s² Frequency Range: 5 ~ 5,000 Hz Max Payload: 200 kg Displacement: 51 mm (p-p)

06 / Mechanical Testing Zone

IMPACT TEST SYSTEM

Uses gravity recoil mechanism to generate high-impact pulses reaching hundreds of G. Tests products on all 6 faces (positive and negative X/Y/Z axes), rigorously evaluating internal PCB components and structural fasteners against instantaneous severe impact.

Standard Pulse: Sawtooth Wave Peak Acceleration: 300 or 400 m/s² Pulse Width: 11 ms (3 per face)

07 / Waterproofing Testing Zone

MILITARY STANDARD RAIN CHAMBER

Designed to strictly comply with GJB150.8A-2009, realistically recreating heavy rainfall battlefield and outdoor conditions. Features multiple program modes, supporting wind-driven rain testing up to 20 m/s and enhanced spray testing.

Rainfall Intensity: 1 ~ 5 mm/min Max Wind Speed: 0 ~ 20 m/s Spray Pressure: ≥276 kPa

08 / Waterproofing Testing Zone

SUBMERSION TEST SYSTEM

Focuses on IPX8-level deep waterproofing qualification for radios and tactical handsets. Uses precision hydraulic pressure simulation technology to accurately recreate water submersion at depth without requiring massive chamber sizes.

Protection Level: IPX8 Max Simulated Depth: 40 meters Standard: 1m depth / 30 ~ 120 min

09 / Salt Fog Corrosion Testing

SALT FOG CORROSION CHAMBER

Accelerated corrosion assessment for extreme environments including coastal areas, high-salinity regions, and humid conditions. High-precision atomization sprays 5% saline solution continuously for 48 or 96 hours.

Rigorous Standard: Upon completion, product exterior and metal surfaces must show zero discoloration, oxidation leakage, coating blistering, or structural erosion — verifying exceptional salt fog durability.

Chamber Temperature: 35°C Saline Concentration: 5% Duration: 48h / 96h

WHAT WE GUARANTEE

Environmental Adaptation

Multi-round high/low temperature cycles and alternating humidity testing rigorously verify product software and hardware adaptation across extreme climatic regions.

Structural Reliability

Multi-axis vibration and high-acceleration impact testing simulate long-distance transport scenarios, eliminating internal loosening and failure risks.

Protection Performance

Rain, submersion, and salt fog testing strictly evaluate IP protection specifications, providing robust defense against moisture, water, and corrosion.

Development & Delivery

Precise, authoritative test feedback for hardware iteration — the foundation for product quality certification and high-standard final delivery.

Hycomms Electronic and Electrlcal Equipment Testing Center

Every device we deliver has been tested, verified, and proven.

From extreme cold to high heat, from high-frequency vibration to deep water pressure — each unit undergoes systematic, full-scenario environmental and mechanical testing before it leaves our facility. That is our commitment to every mission it will serve.
