ISO 6603 Puncture Impact Testing for Rigid Plastics
ISO 6603 is an International standard that determines the puncture impact behavior of rigid plastics. It measures the energy required to puncture a specimen with a hemispherical striker that is dropped from a specified height. This test is commonly used in the plastics industry to evaluate materials' ability to withstand puncture impacts during transportation or handling.

ISO 6603 Puncture Impact Testing Overview
ISO 6603 is an international standard used to determine the puncture impact behavior of rigid plastics subjected to high-speed impact with a falling dart or an instrumented striker. It evaluates how materials respond to multiaxial impact stress, simulating real-life impact conditions such as drops or collisions.
The standard consists of two parts: ISO 6603-1 (non-instrumented) for determining impact failure energy and ISO 6603-2 (instrumented) for measuring force–deflection or force–time behavior. These methods provide detailed insights into toughness, energy absorption, and fracture characteristics of plastic materials.
Scope, Applications, and Benefits
Scope
ISO 6603 testing evaluates:
- Puncture impact energy (J)
- Maximum force and deflection behavior
- Energy absorption and toughness
- Multiaxial stress response
- Failure mode (brittle or ductile)
Applications
- Rigid thermoplastics (PE, PP, ABS, PC)
- Thermosetting plastics and composites
- Fiber-reinforced laminates and sheets
- Automotive and aerospace panels
- Packaging and structural plastic components
Benefits
- Simulates real-world impact conditions
- Provides detailed energy and force data
- Supports material selection for impact resistance
- Identifies brittle vs ductile behavior
- Enhances product safety and durability
ISO 6603 Test Process
Sample Preparation
Flat specimens (typically 1–4 mm thickness) are prepared and conditioned under standard conditions.
1Specimen Clamping
The sample is securely clamped in a fixture to ensure uniform support.
2Impact Application
A falling dart or striker (typically hemispherical tip ~10–20 mm) impacts the specimen at controlled velocity.
3Measurement & Data Interpretation
Impact energy, force, and deflection are recorded to evaluate puncture resistance and failure behavior.

Frequently Asked Questions
ISO 6603 testing involves evaluating how well a plastic stands up to puncture-type impacts. The test involves using a hammer with a hemisphere tip to impact a plastic sheet or molded part, collecting data about impact energies, peak impact forces, and how much deformation occurs before failure.
This is a test for rigid plastics, like thermoplastic or thermoset sheets, laminates, or molded parts, usually in an industrial or structural context.
Among the data collected in this test is how much energy is absorbed, how much force is reached, how much displacement occurs, as well as how well the plastic stands up to puncture.
Unlike tests that receive an impact from only one direction, like Izod or Charpy tests, in an ISO 6603 test, the hemispherical striker strikes the specimen from many directions at once. This is more representative of real-world impacts.
The test uses a drop-weight impact tester with a hemispherical striker, a fixture to hold the specimen in place, force sensors, and displacement sensors connected to a data acquisition system.
