Full title and description
ASTM E517-24 — Standard Test Method for Plastic Strain Ratio r for Sheet Metal. This standard specifies the special tension test procedures, specimen orientations, measurement and calculation methods used to determine the plastic strain ratio (r) — a formability parameter used to assess drawability and earing tendency of sheet metal intended for deep-drawing applications.
Abstract
ASTM E517-24 describes how to perform directional tensile tests on sheet metal specimens, measure width, thickness and longitudinal strains, compute directional r values and weighted averages, and report results for material characterization and quality control. The procedure informs forming-prediction metrics such as r, r0°, r45°, r90° and rn (weighted-average r), and notes units and referencing of related ASTM test practices.

Scope
This test method covers special tension testing for the measurement of the plastic strain ratio, r, of sheet metal intended for deep-drawing applications. It specifies specimen orientation (commonly 0°, 45°, and 90° to the rolling direction), strain measurement and calculation conventions, reporting requirements, and notes on units (inch‑pound units are standard with SI conversions provided as informational). The standard does not replace safety judgments; users must follow applicable safety practices.
Key topics and requirements
- Definition and significance of plastic strain ratio (r) and directional values (r0, r45, r90) used to quantify drawability and earing tendency.
- Specimen geometry, orientation relative to rolling direction, and preparation requirements for reproducible results.
- Strain measurement methods (extensometers or alternative accurate strain-measurement techniques) and calculation of r from width and thickness strains.
- Calculation of weighted-average plastic strain ratio (rn) and guidance for reporting single-direction and averaged values.
- References to related ASTM terminology and precision/bias practices applied to mechanical test methods (cross-references to other ASTM test practices where appropriate).
Primary test method details and reporting conventions are specified in the body of E517-24.
Typical use and users
Used by metallurgical and materials test laboratories, automotive OEMs and suppliers, sheet‑metal fabricators, quality/inspection departments, and R&D teams concerned with formability and deep‑drawing performance of sheet steels, aluminium alloys and other sheet materials. Typical applications include material specification, incoming inspection, process control, and research into forming behavior and earing.
