ISO 11003-1 Structural Adhesive Torsion Test by butt-bonded hollow cylinders

ISO 11003‑1 Adhesives — Determination of shear behaviour of structural adhesives — Part 1: Torsion test method using butt‑bonded hollow cylinders

ISO 11003‑1 defines a torsion‑based shear test to characterise shear‑stress‑shear‑strain behaviour (including shear modulus, shear strength and failure strain) of structural adhesive bonds, delivering input data for advanced engineering design such as finite‑element analysis (FEA).   

ASTM D5448 Inplane Shear Test of Hoop Wound Polymer Composites

ASTM D5448 Standard Test Method for Inplane Shear Properties of Hoop Wound Polymer Matrix Composite Cylinders

ASTM D5448 is a mechanical test for determining in-plane shear properties of hoop-wound (≈90°) polymer matrix composites reinforced with high-modulus continuous fibers.The specimen is a thin-walled cylindrical tube loaded in torsion to obtain shear-dominated material behavior in the fiber/transverse plane.It does not test a flat laminate coupon in rail/shear; it uses a cylindrical winding geometry representative of filament-wound structures.

EN 14869-1 butt-bonded hollow cylinder adhesive torsion testing

EN 14869‑1 Structural adhesives — Determination of shear behaviour of structural bonds — Part 1: Torsion test method using butt‑bonded hollow cylinders.

EN 14869‑1 defines a hollow‑cylinder torsion test to characterise full shear‑stress‑strain performance of structural adhesive bonds and deliver material input data for finite‑element joint simulation. Compared to its base ISO 11003‑1:2001, adds safety clauses, formal terminology section, alternative bond‑line thickness control options, updated European normative references and revised figures and calculation sub‑clauses.

ASTM E229 Napkin-Ring Torsion Test for Structural Adhesive

ASTM E229 Standard Test Method for Shear Strength and Shear Modulus of Structural Adhesives. 

ASTM E229 defines a napkin‑ring torsion shear test (annular bonded ring specimen) for measuring shear strength and shear modulus of structural adhesives in thin constrained bond‑lines. It evaluates structural adhesives in a thin glueline that is restrained by relatively high‑modulus adherends and loaded in torsion.
