Introduction to ISO 10113

In the world of metal testing and manufacturing, ISO 10113 plays a vital role in determining how sheet and strip metals behave under tensile stress. For Malaysian manufacturers involved in automotive, aerospace, or heavy industry, ISO 10113 provides a standardized method to measure plastic strain ratios—also known as r-values—to evaluate the formability of metals.
By implementing ISO 10113, manufacturers can ensure their materials have the right mechanical properties for applications where metal deformation is involved. Whether you’re a quality control specialist or a research engineer, understanding ISO 10113 is essential for producing reliable, formable, and high-performance metal components.
What is ISO 10113?

ISO 10113 is an international standard that outlines the method for determining the plastic strain ratio (r-value) in metallic sheet and strip materials. The r-value is a critical measurement used to assess the anisotropy of a material—how it behaves differently depending on the direction of the applied stress.
The r-value, as described in ISO 10113, is the ratio of the true plastic strain in width to that in thickness during a uniaxial tensile test. A higher r-value indicates better resistance to thinning and, hence, improved deep drawability, which is crucial in stamping and forming operations.
Why ISO 10113 is Important in Malaysia

In Malaysia, industries such as automotive manufacturing, metal fabrication, and appliance production rely heavily on the ability to form and shape sheet metal components. ISO 10113 ensures that these materials can withstand deformation without compromising quality. For companies aiming to comply with SIRIM, ISO 9001, or export standards, adhering to ISO 10113 can significantly boost product reliability and marketability.
Applications of ISO 10113 in Malaysian Industries
1. Automotive Sector

In automotive manufacturing, ISO 10113 is used to evaluate how well sheet metals can be shaped into body panels, frames, and reinforcements. Materials that pass the ISO 10113 standard are less likely to tear, crack, or warp during high-pressure stamping processes.
2. Metalworking and Tooling

Companies involved in tool and die making, particularly those in Selangor and Johor, use ISO 10113 to test material formability before investing in tooling. Using ISO 10113 ensures the right metal is selected for specific forming applications.
3. Appliance and Electronics Manufacturing

Sheet metal is also used in making electronic casings, panels, and frames. Ensuring these materials meet ISO 10113 helps maintain structural integrity and production consistency.
How ISO 10113 Testing is Performed

To conduct an ISO 10113 test, a specimen of sheet metal is subjected to a tensile load using a Universal Testing Machine. During the test, measurements are taken of the width and thickness of the specimen as it elongates. These measurements are used to calculate the plastic strain ratio according to the equations detailed in ISO 10113.
Victor Manufacturing offers a range of Universal Testing Machines capable of performing ISO 10113 tests with high precision, helping labs and manufacturers carry out compliance testing efficiently and accurately.
Benefits of Using ISO 10113 in Quality Control
- Improved Material Selection:
Engineers can select materials with the right r-value for forming applications. - Reduced Material Waste:
Minimizes cracking and thinning, leading to more efficient use of raw materials. - Compliance with Global Standards:
Products tested under ISO 10113 are accepted in international markets. - Reliable Manufacturing:
Ensures repeatable, high-quality results in mass production.
Common Materials Tested with ISO 10113





Each of these materials can behave differently under stress, which is why ISO 10113 is crucial in testing their behavior before use in production.
Testing Equipment for ISO 10113


If you’re looking to conduct ISO 10113 tests in-house, consider using desktop or floor-standing Universal Testing Machines like the VEW 260E or VEW 2307E by Victor Manufacturing. These machines support tensile testing protocols required by ISO 10113 and come with software that makes r-value calculations straightforward.
Conclusion: Why ISO 10113 Is Essential for Malaysian Manufacturers
Adopting ISO 10113 in your testing workflow ensures that your materials meet the demands of modern manufacturing. With its emphasis on plastic strain ratios, ISO 10113 supports better forming performance, consistent quality, and international compliance. Whether you’re producing automotive panels in Klang Valley or fabricating metal parts in Penang, ISO 10113 helps your team deliver products that are formable, durable, and reliable.
