International Standard Testing Laboratory

Ensuring Maximum Confidence, Quality, and Reliability for Next-Generation Mobility

Behind every high-performance wire harness—from low voltage vehicle networks to high voltage EV powertrains—stands the absolute requirement for zero-defect safety and uncompromising stability.

At Thai Summit Harness Public Company Limited, we continuously invest in our state-of-the-art Testing & Validation Laboratory. Built within certified cleanroom environments and equipped with world-class testing equipment, our laboratory replicates the most demanding real-world operating conditions, upholding our corporate commitment: "Satisfy Customers with our Products and our Professionalism."

Comprehensive Testing Capabilities

1. Environmental & Climatic Simulation

Automobiles face unpredictable weather and environmental conditions. Our laboratory features comprehensive climatic simulation systems:

• High Pressure Rain & Spray Test Chamber: Evaluates waterproof sealing performance and high-pressure jet resistance (IP Testing).
• Dust Test Chamber: Tests resistance against fine airborne particulates and dust accumulation.
• Temperature & Climatic Chamber / High-Temperature Chamber: Evaluates long-term tolerance under extreme temperatures and relative humidity.
• Thermal Shock Chamber: Assesses material expansion and structural resistance under rapid temperature fluctuations.
• Ozone Test Chamber & Weather-Ometer: Evaluates degradation and weathering of rubber, silicone, and polymers against ozone gas and UV radiation.

2. Mechanical & Durability Testing

Vehicle dynamics and vibrations subject wire harnesses to continuous stress:

• Multi-Axis Vibration Testing: Simulates harsh road profiles to detect connector looseness, contact fretting, and conductor fatigue.
• Wire Bending & Flexure Test Machine: Evaluates continuous bending endurance for dynamic harness joints (doors, tailgates).
• Universal Testing Machine (UTM): Measures tensile pull-off force, compressive strength, and crimp joint terminal retention.
• Flammability Test Chamber: Validates flame retardance and self-extinguishing properties of insulations under automotive safety regulations.

3. Electrical Performance & High Voltage Validation

Engineered to validate high-voltage electric vehicle (xEV) and modern automotive electronics:

• Withstand Voltage & Insulation Resistance Testers: 100% verification against electrical leakage and dielectric breakdown under high voltage.
• LCR HiTester: High-precision measurement of resistance, inductance, and capacitance across signal lines.

4. Material & Microstructure Analysis

Deep microscopic inspection to detect microscopic flaws invisible to the naked eye:

• X-ray Inspection & Cross-Section Imaging: Non-destructive structural inspection of terminal crimp compaction and internal weld integrity.
• High-Precision Measuring Microscope: Verifies dimensional tolerances and micro-clearances of molded components.
• X-ray Fluorescence Spectrometer (EDX-7000): Elemental and chemical analysis ensuring strict compliance with global environmental regulations (RoHS, ELV, REACH).
