Overview

EN 382-2:1993 is the CEN standard that specifies a test method to determine the surface porosity and surface absorption characteristics of hardboards, with reference to EN 316. This method supports consistent evaluation of hardboard surface behavior, helping manufacturers, testing laboratories and specifiers assess how boards will interact with coatings, adhesives and finishing processes.

The standard has been adopted nationally in various forms (for example, SIST EN 382-2:1996 in Slovenia) and forms part of the wider body of fibreboard test methods used for product quality and compliance.

Key Topics

• Purpose: Defines a reproducible test method to quantify surface absorption or porosity of hardboards.
• Scope: Applies specifically to hardboards as described in EN 316 and provides a basis for comparative evaluation between products.
• Test intent: Assess surface properties that influence coating uptake, adhesive penetration and surface finishing performance.
• Reproducibility: Establishes a standardized approach so results are comparable across laboratories and production batches.

Keywords: hardboards, surface absorption, surface porosity, EN 316, CEN test method, quality control, coating performance.

Applications

The EN 382-2:1993 method is used across industry and laboratory contexts where the surface behavior of hardboards matters. Typical applications include:

• Quality control at production facilities to monitor surface consistency between batches.
• Evaluation of coating and finishing performance to inform paint or varnish selection and process settings.
• Assessment of how adhesives or laminates will interact with hardboard surfaces during bonding processes.
• Comparative testing for product development and material selection.

Benefits of applying EN 382-2:1993:

• Improved product consistency through standardized measurement.
• Better coating and adhesive performance predictions based on measured surface absorption.
• Objective data to support specifications, supplier comparisons and compliance activities.

Related Standards

• EN 316 - referenced in EN 382-2:1993 as the description basis for hardboards; consult EN 316 for material definitions used by the test method.
• National adoptions such as SIST EN 382-2:1996 reflect the standard's integration into local regulatory and quality systems.
• Other documents in the EN 382 series and related fibreboard test methods provide complementary procedures for broader material characterization.

For implementation, testing laboratories and manufacturers should refer to the full EN 382-2:1993 text and any applicable national adoptions to ensure correct application and reporting of results.
