ISO 20864:2004 specifies three methods for determining the shape retention properties and compression strength of a domed test specimen. These methods are the following and they are applicable to footwear toepuff and stiffener: method 1: applicable to heat activated materials method 2: applicable to solvent activated materials method 3: applicable to non-thermoplastic fibreboard

Overview

EN ISO 20864:2004 - "Footwear - Test methods for stiffeners and toepuffs - Mechanical characteristics" (CEN adoption of ISO 20864:2004) defines standardized laboratory procedures to evaluate the shape retention and compression strength of domed test specimens used for footwear toepuffs and stiffeners. The standard specifies three distinct methods tailored to common material types: heat‑activated, solvent‑activated, and non‑thermoplastic fibreboard components.

Key topics and technical requirements

Three test methods

Method 1: For heat‑activated materials (oven activation then dome forming).
Method 2: For solvent‑activated materials (solvent application then forming).
Method 3: For non‑thermoplastic fibreboard (moulding under hydraulic press/steam).

Measured properties

Shape retention value (ability to maintain the domed shape after repeated loading).
Collapsing (compression) load - force required to deform the dome.
Shape retention after ten collapses, resilience, and moisture resistance.

Apparatus and dimensions

Standardized dome forming tools or two‑part moulds, height gauges with specified spindle geometry and force, compression plunger (approx. 19 mm diameter), and tensile/compression testing machines with defined accuracy (force measurement per EN ISO 7500‑1).
Conditioning and sampling requirements (controlled atmospheres per EN 12222), specimen cutting and clamping, activation procedures (heat or solvent) and controlled cooling/settling before testing.

Test procedure essentials

Conditioning, forming the domed specimen, repeated compression cycles or single collapse tests, and clear instructions for expressing results and reporting.

Applications and users

Footwear manufacturers - validate and compare toepuff and stiffener materials during product development or incoming quality control.

Component suppliers - specify mechanical characteristics for material data sheets and supplier declarations.

Testing laboratories - perform accredited mechanical tests for compliance, R&D and failure analysis.

Design and R&D teams - select appropriate stiffener/toepuff materials to meet performance and comfort requirements (shape stability, support, durability).

Quality assurance - integrate results into acceptance criteria and supplier audits.

Keywords: EN ISO 20864:2004, footwear test methods, stiffeners, toepuffs, mechanical characteristics, shape retention, compression strength, dome test specimen.
