BS ISO 20064:2019 - A Comprehensive Guide to Determining Brittle Crack Arrest Toughness in Steel
In the world of engineering and materials science, understanding the properties of materials is crucial for ensuring safety, reliability, and performance. The BS ISO 20064:2019 standard is an essential resource for professionals dealing with metallic materials, specifically steel. This standard provides a detailed method for testing and determining the brittle crack arrest toughness, denoted as Kca, which is a critical parameter in assessing the fracture resistance of steel materials.
Overview of BS ISO 20064:2019
Released on July 26, 2019, the BS ISO 20064:2019 standard is a comprehensive document spanning 54 pages. It is a part of the international standards that focus on the properties of metallic materials, providing a standardized method to evaluate the ability of steel to arrest the propagation of brittle cracks. This is particularly important in applications where steel is subjected to low temperatures or high-stress conditions, where the risk of brittle fracture is heightened.
Key Features and Benefits
- Standard Number: BS ISO 20064:2019
- ISBN: 978 0 580 90508 7
- Status: Standard
The BS ISO 20064:2019 standard is designed to provide a reliable and repeatable method for testing steel materials. By following this standard, engineers and researchers can ensure that their materials meet the necessary safety and performance criteria. The standard is applicable to a wide range of steel types and is particularly useful in industries such as construction, automotive, and aerospace, where material failure can have catastrophic consequences.
Understanding Brittle Crack Arrest Toughness (Kca)
Brittle crack arrest toughness, Kca, is a measure of a material's ability to stop the propagation of a crack once it has started. This property is crucial for preventing sudden and catastrophic failures in steel structures. The BS ISO 20064:2019 standard outlines a specific test method to determine this property, ensuring that the results are consistent and reliable across different laboratories and testing conditions.
The test method described in the standard involves subjecting a steel specimen to controlled conditions that simulate the stresses and temperatures it would experience in real-world applications. By measuring the material's response to these conditions, engineers can determine its Kca value and assess its suitability for use in critical applications.

This standard BS ISO 20064:2019 Metallic materials. Steel. Method of test for the determination of brittle crack arrest toughness, Kca is classified in these ICS categories:
- 77.040.10 Mechanical testing of metals
This document specifies a test method for the determination of brittle crack arrest toughness.
It is applicable to ferritic steel base metals exhibiting ductile to brittle transition behaviour. Applicable materials are rolled steel plates. It is intended for materials with a tensile strength of 950 MPa or less and a test piece thickness of 200 mm or less. The range of arrest temperatures is between ?196 °C and +100 °C. This document can be applied to flat rolled steel plates but not to flattened steel pipes because the flattening can cause changes in arrest toughness.
