Product Testing Equipment
Comprehensive quality validation for party speakers, wooden speakers, and trolley speakers
Salt Spray Corrosion Testing
Neutral salt spray test (NSS): 5% sodium chloride solution, atomized for 12 continuous hours. This test evaluates the corrosion resistance of metal components, fasteners, grilles, and surface finishes. We check for discoloration, metal corrosion distribution, cracks, and bubbles on all exposed surfaces. The IQC department is responsible for incoming material testing and sample verification.
Test Parameters
- Sodium chloride concentration: 5% ±1% by weight
- pH value: 6.5–7.2
- Test duration: 12 hours (standard)
- Chamber temperature: 35°C ±2°C
- Atomization rate: 1–2 ml/80cm²/hour
Simulated Transport Vibration Testing
Simulates up to 4 hours of overland transport vibration to verify outer packaging integrity. Tests whether internal speakers shift position, and whether the product functions normally after transport simulation. Critical for export shipments traveling by sea, rail, and truck.
Product Coverage
Testing for portable karaoke systems, outdoor speakers, home karaoke systems, and handheld Bluetooth speakers with LED light effects.
