Overview

EN 317:1993 is a European Standard developed by CEN that specifies a precise method for measuring the swelling in thickness of particleboards and fibreboards after they have been immersed in water. This standard applies to various types of boards including flat-pressed, drum-pressed particleboards, fibreboards, and cement-bonded particleboards. Understanding the swelling characteristics is critical for assessing the quality and durability of these materials in environments where moisture exposure is expected.

Key Topics

• Scope of Testing
  The standard focuses on determining the dimensional change-specifically thickness swelling-after immersion in water, providing consistent methods to evaluate water resistance properties of boards used in construction and manufacturing.

• Materials Covered

  • Flat-pressed particleboards
  • Drum-pressed particleboards
  • Fibreboards
  • Cement-bonded particleboards

• Test Procedure
  EN 317:1993 outlines a detailed method that includes sample preparation, immersion duration, and measurement techniques ensuring repeatability and accuracy across laboratories.

• Measurement Focus
  Thickness swelling is measured by comparing the thickness of board specimens before and after water immersion to assess the percentage increase.

Applications

• Quality Control in Manufacturing
  Manufacturers of particleboards and fibreboards use this standard to ensure products meet moisture resistance requirements essential for long-term performance.

• Material Selection for Construction
  Builders and architects rely on thickness swelling data to select suitable boards for areas prone to humidity or water exposure.

• Product Development and Certification
  Research and development teams test new composites for improved dimensional stability, while certification bodies use EN 317 as part of product assessment protocols.

• Regulatory Compliance
  Compliance with EN 317 helps materials meet European market regulations and enhances market acceptance by providing standardized proof of performance.

• EN 318 - Particleboards and fibreboards - Determination of density

Summary

EN 317:1993 is an essential standard for quality assurance and product testing in the wood-based panel industry. By providing a defined method for measuring thickness swelling after water immersion, it helps manufacturers and users ensure their particleboards and fibreboards maintain structural integrity and performance under moisture stress. Integrating EN 317 testing enhances product reliability, supports regulatory compliance, and informs informed material choices for construction and furniture manufacturing sectors.
