**Introduction**

In today's global marketplace, product safety testing is crucial for protecting public health and maintaining consumer trust.
Understanding these key testing parameters provides insight into quality assurance measures.

**Core Testing Categories**

1. **Physical & Mechanical Testing**

   - Evaluates structural integrity and potential hazards

   - Includes:

     * Small parts/choking hazard tests (toys)

     * Sharp edge assessments

     * Stability tests (furniture)

     * Seam strength/tear resistance (textiles)

     * Drop/compression tests (packaging)

2. **Chemical Safety Testing**

   - Identifies harmful substances in products

   - Key regulations: REACH (EU), CPSIA (US)

   - Tests for:

     * Heavy metals (lead, cadmium, mercury)

     * Phthalates, azo dyes, formaldehyde

     * Migration testing (food packaging)

     * Allergens/microbial contamination (cosmetics)

3. **Electrical Safety Testing**

   - Prevents shock and fire hazards

   - Includes:

     * Insulation resistance tests

     * High voltage tests

     * Grounding continuity checks

     * Overcurrent protection evaluation

     * Energy efficiency assessments

4. **Flammability Testing**

   - Assesses ignition resistance and burn rates

   - Varies by product type:

     * Clothing textiles (flame spread)

     * Children's sleepwear (strict standards)

     * Furniture/mattresses (open flame resistance)

     * Building materials (fire resistance)

5. **Performance Testing**

   - Verifies product functionality vs claims

   - Examples:

     * Electronics (battery life, processing speed)

     * Appliances (cleaning efficiency, noise)

     * Toys (durability under play conditions)

**Conclusion**

Comprehensive product testing addresses multiple safety aspects through these key parameters. As technology evolves,
testing methods will continue advancing to ensure product safety and quality in our daily lives.
