Overview - EN 326-1:1994 (CEN)
EN 326-1:1994 is a European standard from CEN that defines rules for the sampling and cutting of test pieces and for the expression of test results for wood-based panels. Its purpose is to ensure that information on the physical and mechanical properties of wood-based panels is collected and reported in a consistent, reproducible way so that laboratory test results are meaningful and comparable.
Key topics and requirements
The standard focuses on practical, repeatable procedures for obtaining reliable test data for wood-based panels. Key topics include:
- Sampling principles to obtain representative test pieces from panel batches or production lots.
- Cutting and preparation of specimens to ensure consistency between laboratories and tests.
- Evaluation and presentation of test results, including how results should be expressed to allow clear interpretation and comparison.
- Emphasis on traceability and documentation so test pieces and results can be related back to the original panel batch or production conditions.
Note: EN 326-1 sets procedural rules rather than prescribing specific performance values. It standardizes how test pieces are taken and how results are reported so downstream testing and certification are comparable.
Applications and who uses it
EN 326-1 is used wherever standardized panel testing and quality assurance are required:
- Manufacturers of particleboard, MDF, plywood and other wood-based panels for internal quality control and production monitoring.
- Independent testing laboratories to ensure test specimens are prepared to a recognized European procedure.
- Certification bodies and conformity assessment organizations that need consistent sampling and reporting methods for product evaluation.
- R&D teams and product developers performing comparative testing during development or material selection.
- Specifiers and purchasers who require confidence in reported panel properties by ensuring tests follow recognized sampling and reporting methods.
Practical value / benefits
- Improves repeatability and comparability of test results across labs and countries.
- Helps reduce sampling bias and inconsistencies in specimen preparation.
- Enhances clarity of test reports by standardizing how results are expressed.
- Supports regulatory compliance, product certification, and quality assurance programmes for wood-based panels.
Related standards
- EN 326 series (other parts) and other EN standards for wood-based panel test methods govern inspection and specific test procedures.
- National adoptions (e.g., SIST EN 326-1:1996) reflect local implementation of the EN 326-1 rules.
