This document specifies the requirements and corresponding test methods for moulded forms, e.g. sheets and rods, made from ultra-high-molecular-weight polyethylene (UHMWPE) for use in the manufacture of surgical implants. This document is not applicable to direct-moulded (near net shape), irradiated or finished products or products manufactured from polyethylene blended with additives or by blending different forms of polyethylene.

Le présent document spécifie les exigences et les méthodes d'essai correspondantes pour les produits sous forme moulée, par exemple plaques et bâtonnets, à base de polyéthylène à très haute masse moléculaire (PE-UHMW), utilisés dans la fabrication d'implants chirurgicaux. Le présent document ne s'applique pas aux produits directement moulés (à côtes semi-finies), aux produits irradiés ou finis ni aux produits fabriqués à partir de polyéthylène mélangé à des additifs ou obtenus en mélangeant différentes formes de polyéthylène.

Overview

ISO 5834-2:2019 is an international standard specifying the requirements and test methods for moulded forms of ultra-high-molecular-weight polyethylene (UHMWPE) used in surgical implants. It covers products such as sheets and rods made from UHMWPE powder, focusing on their physical properties and quality assurance to ensure safety and performance in medical applications. The standard excludes direct-moulded near-net-shape, irradiated, finished products, or polyethylene blended with additives.

Key aspects include physical property thresholds, manufacturing process controls, and mandatory testing protocols. UHMWPE moulded forms complying with this standard provide reliable materials for the fabrication of durable and biocompatible surgical implants.

Key Topics

  • Scope and applicability
    ISO 5834-2:2019 applies to UHMWPE moulded forms derived from specified powders (Type 1, 2, or 3 per ISO 5834-1) used in implant manufacturing. It prohibits the use of mould-release agents like silicone or talc to avoid contamination.

  • Material classification
    The standard classifies moulded UHMWPE based on the powder type used: Type 1, Type 2, or Type 3, ensuring traceability and consistency.

  • Manufacturing requirements

    • Traceability through batch or lot numbers is mandatory.
    • Optional stress-relief annealing may be performed upon implant manufacturer request.
    • No liquid or powder mould-release agents allowed in production.
  • Physical properties and mechanical limits
    The standard defines strict minimum criteria for:

    • Density (927–944 kg/m³)
    • Tensile yield strength (minimum 19–21 MPa depending on type)
    • Tensile strength at break (minimum 27–40 MPa)
    • Elongation at break (minimum 250–380%)
    • Impact resistance via Izod notched test (minimum 25–126 kJ/m²)
  • Particulate contamination control
    The package must not exhibit more than 10 visible surface particles per defined inspection area to minimize implant contamination.

  • Test methods
    Testing aligns with ISO 1183-1 for density and ASTM F648 for mechanical properties. Conditions are standardized at 23 ± 2°C after specimen conditioning.

  • Marking and documentation
    Each delivery lot requires unique identification marks for traceability and must include a conformity test report detailing classification, batch number, test results, and any annealing treatment.

Applications

ISO 5834-2:2019 is critical for manufacturers and suppliers of surgical implants who use UHMWPE moulded forms. This standard helps ensure:

  • Medical implant safety and reliability
    By specifying material quality and mechanical performance, it supports the creation of long-lasting joint replacements, bone plates, and other orthopedic devices.

  • Regulatory compliance
    Adherence assists implant producers in meeting regulatory demands for medical device materials, enhancing market acceptance worldwide.

  • Quality assurance in surgical implants
    The standard’s traceability and testing requirements reduce risks of implant failure due to material defects or contamination.

  • Material selection guidance
    Surgeons and device designers can rely on standardized UHMWPE grades to match implant design requirements for strength and durability.

Related Standards

  • ISO 5834-1: Implants for surgery - UHMWPE - Part 1: Powder form
    Defines the types of UHMWPE powder from which the moulded forms in Part 2 are produced.

  • ASTM F648: Standard specification for UHMWPE powder and fabricated form for surgical implants
    Provides mechanical test methods referenced by ISO 5834-2.

  • ISO 1183-1: Plastics - Determination of density of non-cellular plastics - Immersion and pycnometer methods
    The method specified for density measurements of UHMWPE moulded products.

  • ISO 11542-1 & 11542-2: Plastics based on UHMWPE for moulding and extrusion
    Complementary standards covering designations, preparation, and property determination relevant to UHMWPE materials.

Summary

Adoption of ISO 5834-2:2019 ensures that UHMWPE moulded forms used in surgical implants meet internationally recognized requirements for material integrity, mechanical performance, and purity. This fosters safer, longer-lasting medical implants and smooth regulatory approval processes. Manufacturers can confidently produce and supply UHMWPE sheets and rods with traceable quality, benefiting healthcare providers and patients worldwide.
