ISO 10113:2006 specifies a method for determining the plastic strain ratio of metallic flat products such as sheet and strip. This r-value is commonly used when assessing sheet-metal formability and resistance to thinning during deformation.
If you need help determining whether ISO 10113:2006 (or the newer ISO 10113:2020) is the right reference for your material, grips, and strain-measurement approach, talk with our team about your test setup and reporting requirements.
ISO 10113:2006 — Metallic materials — Sheet and strip — Determination of plastic strain ratio
This standard addresses plastic anisotropy in metallic sheet and strip by defining a method to determine the plastic strain ratio (often referenced as an r-value). It is used in material characterization programs where forming performance and consistency matter.
Status note: ISO 10113:2006 is withdrawn and has been replaced by ISO 10113:2020. When a customer specification calls out “ISO 10113:2006,” edition matching and change control are important.
Quick Definition
ISO 10113:2006 is a mechanical test method for determining the plastic strain ratio of metallic sheet and strip, typically as part of sheet-metal formability evaluation.
| Item | What it means for your lab |
|---|---|
| Primary output | Plastic strain ratio (r-value) for flat metallic products |
| Test type | Method-based mechanical testing focused on plastic strain behavior |
| Specimen form | Sheet and strip (flat products) |
| Status | Withdrawn (replaced by ISO 10113:2020) |
What This Standard Covers
ISO 10113:2006 defines a method to determine the plastic strain ratio for metallic sheet and strip. In practice, this means measuring plastic deformation behavior in a way that supports evaluation of anisotropy in flat-rolled products.
This standard is focused on the r-value determination itself; it is not a general-purpose “sheet-metal qualification” document and does not replace the product or forming requirements that may exist in customer or industry specifications.
Why This Standard Matters in Testing
The r-value is widely used when comparing sheet materials for forming operations where thinning resistance and directional behavior can impact production stability. When ISO 10113 is specified, it typically means r-value results will be used for material selection, incoming verification, process control, or supplier qualification.
Because the result depends on how strain is measured, the measurement approach (contact vs. non-contact, axial and transverse strain capability, and calibration/verification practices) can be as important as the load frame itself.
Common Materials, Product Types, or Applications Covered
ISO 10113:2006 applies to flat metallic products, specifically sheet and strip.
- Sheet metals used for forming operations (for example, parts that undergo drawing or stretching)
- Strip materials where anisotropy and thinning resistance are relevant to downstream forming
- Programs comparing directional properties in rolled products
Common Test or Verification Workflow
When ISO 10113 is invoked in a lab workflow, it is commonly integrated into a tensile-based characterization sequence for sheet/strip. The workflow generally centers on generating reliable strain data so the plastic strain ratio can be calculated for the specified conditions.
Common workflow elements: Specimen preparation from sheet/strip, tensile loading with appropriate gripping, measurement of longitudinal and transverse strain over the required range, calculation of plastic strain ratio, and reporting aligned to the purchasing or qualification requirement.
Equipment Commonly Used for This Standard
ISO 10113:2006 typically points to a tensile-testing-capable setup with strain measurement in more than one direction. Equipment selection usually focuses on stable gripping for thin flat specimens and repeatable axial/transverse strain measurement.
Common equipment: Universal testing machine (electromechanical or servo-hydraulic, depending on force range and throughput), sheet/strip tensile grips, and extensometry capable of measuring both longitudinal and transverse strain (contacting biaxial extensometry or suitable non-contact/video extensometry).
If you are configuring a system for sheet/strip r-value work and want to compare extensometer options and gripping approaches, you can request a detailed quote for a configuration matched to your specimen geometry and output requirements.
How to Read This Designation or Revision
ISO 10113:2006 identifies ISO standard number 10113 with a 2006 publication year (Edition 2). This edition is withdrawn, and ISO identifies ISO 10113:2020 as the newer version.
Practical caution: If a contract, drawing note, or customer requirement cites ISO 10113:2006 explicitly, avoid automatically substituting another edition without customer approval. Test setup details and reporting expectations can be edition-sensitive.
Related Standards, Methods, or Frameworks when useful
ISO 10113 r-value work is commonly performed alongside tensile property testing for sheet metals, and it is often referenced in the same decision-making context as other sheet-metal formability indicators.
Common pairing in practice: Tensile-based material characterization where r-value is evaluated together with other tensile/formability-related outputs, depending on the governing customer or product specification.
