Overview

EN 1438:1998 - Symbols for timber and wood-based products is a CEN standard that defines a comprehensive set of symbols and character types for use in technical documents, labelling and drawings covering solid timber and all wood‑based materials. The standard presents symbols as letter types in alphabetical order and aligns Clause 5 with the layout conventions of ISO 3898, promoting consistent presentation across documents. National adoptions (for example, SIST EN 1438:2003) reflect its use in member countries.

Key topics and requirements

  • Scope and applicability: Symbols cover solid timber and a wide range of wood‑based products used in documentation, specification and marking.
  • Symbol format: All symbols are provided as standardized letter‑type characters and arranged alphabetically for easy reference.
  • Layout conformity: Clause 5 follows the layout of ISO 3898, ensuring compatibility with existing international symbol presentation practices.
  • Document consistency: The standard supports uniform representation of material types, processing states and other product identifiers in technical drawings and written specifications.
  • Multilingual presentation: Titles and references are provided in multiple languages to aid international use (as seen in national publications).

Note: EN 1438 defines the symbols and presentation rules; it does not replace product performance or classification standards.

Practical applications

  • Creating consistent technical drawings, specification sheets and material schedules for construction, joinery and furniture design.
  • Standardizing product labels, catalogs and documentation used by manufacturers, distributors and suppliers of timber and wood‑based panels.
