Overview
EN 323:1993 is a European Standard published by CEN that specifies a method for determining the density of test pieces of wood-based panels. The measured density can be used to estimate panel density in accordance with EN 326-1, clause 6. This standard is identified in the ICS classification for wood-based panels (79.060.01) and has been adopted nationally (for example as SIST EN 323:1996 in Slovenia).
EN 323:1993 provides a clear, repeatable reference method for laboratories, manufacturers and compliance bodies to obtain reliable density data without prescribing unrelated parameters or product-specific limits.
Key Topics
- Scope and purpose: Defines the scope of density determination for wood-based panel test pieces and links results to EN 326-1 estimations.
- Applicability: Intended for all types of wood-based panels where density measurement is required for classification, testing or quality assessment.
- Standard identification: Reference code EN 323:1993 (also published nationally under various adoption numbers such as SIST EN 323:1996).
- Practical role: Provides a standardised measurement outcome that supports downstream testing, specification and compliance activities.
Applications
EN 323:1993 is used across the wood-panel value chain and by third-party testing organizations for practical purposes including:
- Quality control: Routine production checks to monitor density consistency and detect deviations that may affect mechanical performance or finishing.
- Material classification: Assigning panels to density classes for product specification and marketing information.
- Product development: Informing design decisions where density influences strength, weight and dimensional stability.
- Regulatory and conformity assessment: Generating data used in compliance reporting or to support declarations where density is a relevant parameter.
- Research and comparison: Providing comparable density data across materials and studies when a harmonised method is required.
Related Standards
- EN 326-1 - referenced in EN 323 for the use of density results in estimating panel density (see clause 6 of EN 326-1).
- National adoptions of EN 323:1993 (for example SIST EN 323:1996) reflect the standard's acceptance and application at member-state level.
Practical value
Using EN 323:1993 ensures consistent, repeatable density measurements that support product specification, quality assurance and cross-laboratory comparison. For manufacturers, laboratories and specifiers, the standard is a fundamental reference when density is a key material attribute.
