What is impact testing?
Impact testing is a reliability evaluation method used to assess how products or materials respond to sudden mechanical shocks such as drops, collisions, or high acceleration forces. It helps identify structural weaknesses, improve durability, and ensure compliance with standards like IEC 60068-2-27.
In practical applications, impact testing simulates real-world mechanical shock conditions that occur during transportation, handling, installation, and product use.
These events generate short-duration, high-intensity forces that may cause structural damage, internal component failure, or functional degradation.
According to international standards such as IEC 60068, environmental testing methods are used to evaluate how products withstand mechanical and climatic stresses throughout their lifecycle.
In simple terms: impact testing helps manufacturers detect failures before products reach the market.
Why Impact Testing Matters in Modern Manufacturing
For manufacturers, impact testing is not just a lab procedure—it directly affects:
✔ Product Reliability
Ensures products survive real-world shocks without failure
✔ Certification Compliance
Supports standards such as IEC 60068-2-27 and UN 38.3
✔ Cost Reduction
Minimizes returns, warranty claims, and recalls
✔ Brand Trust
Demonstrates quality and engineering capability
IEC 60068-2-27 specifically defines how products are subjected to controlled shock forces to evaluate resistance and identify weaknesses
Main Types of Impact Testing
Mechanical Shock Testing
Mechanical shock testing simulates controlled impulse forces over very short durations.
Typical waveforms include:
- Half-sine
- Sawtooth
- Trapezoidal
These waveforms are defined in standards such as IEC 60068-2-27 to replicate real-world shock conditions
Drop Testing
Drop testing simulates real-life events such as:
- Packaging drops
- Handling accidents
- Transportation impacts
Material Impact Testing
Material-level testing evaluates:
- Toughness
- Energy absorption
- Fracture resistance

Key Impact Testing Standards
To ensure global compliance, manufacturers must follow international standards:
- IEC 60068-2-27 – Mechanical shock testing
- IEC 60068 series – Environmental testing framework
- UN 38.3 – Lithium battery transport safety
- ISO 179 – Material impact testing
These standards define:
- Test conditions
- Pulse shapes

- Evaluation criteria
Key Parameters in Impact Testing
Understanding test parameters is essential for accurate results:
- Acceleration (g): determines shock intensity
- Pulse duration (ms): defines impact time
- Shock direction: X, Y, Z axes
- Shock response spectrum (SRS): evaluates system response
Advanced testing may use SRS synthesis to simulate complex real-world shock environments
How to Choose the Right Impact Testing Equipment?
When selecting equipment, consider:
✔ Test Standards
Does it comply with IEC / ISO / UN requirements?
✔ Application Scenario
- Product testing → shock tester
- Packaging → drop tester
