Electronic Product Safety Testing Laboratory

Every country worldwide has its own safety regulations. Many countries also enforce mandatory certifications, such as the EU’s CE mark. Some certification marks have earned strong market reputations; many manufacturers require suppliers to obtain relevant safety certifications to enhance their market safety image. Examples include the UL mark, VDE mark, Nemko mark, and GS mark. These safety logos enjoy good market recognition.

At the same time, as consumers become more rational, they no longer blindly pursue low prices and powerful functions but pay more attention to product safety. How to obtain products that are of complete quality and harmless to users has become an increasingly important factor for consumers. For a safer world, product safety certification will inevitably become more widespread and deeply ingrained.

Seven Major Safety Factors in Electronic and Electrical Products:

1. Electric Shock

2. Energy-related Hazards

3. Fire

4. Heat-related Hazards

5. Mechanical Hazards

6. Radiation

7. Chemical Hazards

During safety certification, products need to meet these key points.

Four Main Tests for Electrical Injury:

1. **Dielectric Withstand / Hipot Test:**

Apply high voltage between the product's power and ground circuits to measure breakdown conditions.

2. **Insulation Resistance Test:**

Measure the electrical insulation state of the product.

3. **Leakage Current Test:**

Check if the leakage current from AC/DC power to ground exceeds standards.

4. **Protective Ground Test:**

Verify whether accessible metal parts are properly grounded.
