ISO 148: Standard for metal impact testing
What is ISO 148?
ISO 148 is an international standard that provides guidelines for performing the Charpy impact test on metals. This standard is essential for assessing the toughness and resistance to breakage of various metals under impact loads. The goal of ISO 148 is to provide consistent and reliable test results that are critical in industries such as aviation, automotive and construction, where there is a strong need for materials that are resistant to shocks and sudden forces.
Why is ISO 148 important?
The application of ISO 148 offers several advantages:
- Increased safety: By understanding the impact resistance of metals, manufacturers can ensure the safety of their products, which is essential in demanding applications.
- Quality Assurance: Using a standardized methodology helps companies maintain high quality standards and meet industry standards.
- Consistency across batches: The standard is important for ensuring consistent metal performance across production batches, contributing to customer satisfaction and trust.
How does ISO 148 work?
The standard requires a specific procedure for the Charpy impact test:
- Sample preparation: The metal sample is cut into a specific shape and prepared according to established standards to ensure the accuracy of the test.
- Test procedure: The sample is exposed to a pendulum in the test setup, which measures the energy required to break the sample.
Relationship with ASTM E23
ASTM E23 is another important standard that provides guidance for impact tests, including both Charpy and IZOD tests. While ISO 148 focuses primarily on metal testing procedures, ASTM E23 covers a wider range of materials, including non-metals. The synergy between these standards helps manufacturers and engineers ensure the quality and safety of their products in various applications.
Applications of ISO 148 in industry
At Deon Research Centre, we are involved in the application of ISO 148 in various sectors:
- Aviation: materials used under extreme conditions are tested to ensure their toughness.
- Automotive: This standard helps analyse vehicle components to improve their durability and safety.
- Building and construction: Thanks to ISO 148, engineers can evaluate the toughness of building materials that are exposed to variable loads.
