Overview

ISO 5326:1978 is an international standard published by the International Organization for Standardization (ISO) that specifies quality requirements for solid hardwood paving blocks. These paving blocks are used for both covered (indoor) and open (outdoor) spaces, providing a durable and aesthetically pleasing surface solution. The standard includes guidelines on permissible wood or sawing defects to ensure consistent product quality and performance.

This standard applies particularly to solid wood paving blocks made from hardwood, with a special note that blocks made from Fagus sylvatica (European beech) are intended exclusively for covered indoor applications due to durability limitations. By defining defect tolerances and quality characteristics, ISO 5326 helps manufacturers, suppliers, and purchasers maintain high-quality hardwood paving products.

Key Topics

  • Scope and Application

    • Covers solid hardwood paving blocks suitable for outdoor and indoor use.
    • Specific restrictions for Fagus sylvatica blocks intended for indoor use only.
  • Permissible Defects and Quality Criteria

    • Decay, suffocated wood, and mould: Not permitted, ensuring long-lasting blocks.
    • Sapwood: Sound and protected against insects; permitted on lateral arrises but limited to 20% of length/width/height.
    • Grain texture and slope: Allowed if natural and without biological adulteration.
    • Cracks and shakes: Deep shakes permitted up to 50% of one dimension; frost cracks are prohibited.
    • Knots: Sound knots allowed on non-face sides within size constraints and spacing rules.
    • Wormholes and wane: Prohibited on face edges; limited on other faces or edges.
    • Saw marks: Allowed if not deeper than 2 mm to maintain surface integrity.
    • Other defects: Permitted if they do not affect block strength or durability.
  • Materials Specifications

    • Focus on solid hardwood timber, broad-leaved species.
    • Application of sawn timber with considerations for defect control.
  • Reference Norm

    • ISO 5327 relates to general characteristics of solid wood paving blocks and complements this standard.

Applications

  • Paving Indoor Spaces:

    • Hardwood blocks meeting ISO 5326 provide attractive, resilient flooring for commercial buildings, museums, sports facilities, and covered walkways.
    • Fagus sylvatica blocks are ideal for covered environments where moisture exposure is controlled.
  • Outdoor Paving:

    • Suitable hardwood species comply with defect limits to withstand weather conditions in pedestrian zones, parks, plazas, and heritage restoration projects.
    • Enhances urban landscapes with environmentally sustainable, durable wooden surfaces.
  • Restoration and Heritage Projects:

    • ISO 5326 ensures quality and consistency for replacement paving blocks in historic areas.
    • Meets stringent aesthetic and performance demands.
  • Manufacturing and Quality Control:

    • The standard guides manufacturers in grading timber and inspecting finished blocks.
    • Supports suppliers in ensuring compliance before delivery, minimizing returns or field failures.

Related Standards

  • ISO 5327: Solid wood paving blocks - General characteristics, complementing ISO 5326 by outlining physical and dimensional attributes.

  • ISO/TC 99: Technical committee responsible for semi-manufactures of timber, overseeing updates and improvements to these standards.

  • Wood Products and Timber Standards: Other related ISO standards for timber grading, durability testing, and wood product specifications may be used in conjunction for comprehensive quality assurance.

ISO (the International Organization for Standardization) is a worldwide federation
sf national Standards institutes (ISO member bodies). The work of developing
International Standards is carried out through ISO technical committees. Every
member body interested in a subject for which a technicai committee has been set
up has the right to be represented on that committee. International organizations,
governmental and non-governmentai, in liaison with ISO, also take part in the work.
Draft International Standards adopted by the technical committees are circulated
to the member bodies for approval before their acceptance as International
Standards by the ISO Council.
International Standard ISO 5326 was developed by Technical Committee
ISO/TC 99, Semi-manufactures of timber, and was circulated to the member bodies
in July 1976.
lt has been approved by the member bodies of the following countries :
