EN 324-2:1993

Overview

EN 324-2:1993 (CEN) specifies methods for measuring the squareness and edge straightness of whole flat wood-based panels. This part of the EN 324 series focuses exclusively on the geometric relationships and straightness of panel edges; the determination of thickness, width and length is covered in Part 1 of the standard.

This standard is intended for use by manufacturers, testing laboratories, auditors and procurement professionals who require repeatable methods to assess panel dimensional quality and conformity to contractual or regulatory requirements.

Key Topics

• Scope and application: Applies to whole, flat wood-based panels; establishes measurement objectives for squareness (right-angle conformity) and edge straightness.
• Measurement principles: Sets out standard methods to determine whether panel edges and corners meet expected geometric conditions for squareness and straightness. (The specific measurement procedures and definitions are provided in the standard text.)
• Relationship to other dimensions: Clarifies that thickness, width and length measurement are defined in Part 1 of EN 324.
• Quality metrics: Focuses on dimensional accuracy and the practical need to control panel geometry during production and inspection.

Applications

EN 324-2:1993 supports practical use across the wood-panel supply chain by enabling consistent, objective assessment of panel geometry. Typical applications include:

• Manufacturing quality control: Routine checks on production lines to detect deviations in squareness or edge straightness early, reducing waste and rework.
• Incoming inspection: Verifying delivered panels meet specified geometric requirements before assembly, finishing or sale.
• Contract compliance and certification: Documenting conformity for contracts, technical approvals and third-party certification schemes.
• Product development and R&D: Comparing production methods, tooling and finishing processes to improve dimensional stability and edge quality.

Benefits

• Improved dimensional accuracy and fit in downstream processes (furniture, flooring, joinery).
• Reduced assembly issues and better end-product quality.
• Consistent inspection criteria across suppliers and laboratories.

Related Standards
