Overview

EN 772-13:2000 (CEN) specifies a standardized method for determining the net (absolute) and gross (apparent) dry density of masonry units, excluding natural stone. This European test method is part of the EN 772 series on methods of test for masonry units and is used to characterize the volumetric mass of clay, concrete, calcium silicate and other manufactured masonry elements under dry conditions.

Key topics and requirements

• Scope and applicability: Applies to manufactured masonry units (except natural stone) for use in quality control, specification and product classification.
• Definitions: Distinguishes net (absolute) dry density - density based on the solid material volume - and gross (apparent) dry density - density based on the overall external volume of the unit (including voids/holes).
• Sample conditioning: Units are conditioned to a dry state (typically by drying to constant mass) prior to measurement to ensure repeatable dry density results.
• Measurement essentials: Covers measurement of mass and volume (by dimensional measurement or displacement methods where applicable), and the calculations used to derive net and gross dry densities.
• Reporting: Specifies the required information to report with test results (test conditions, sample identification, measured masses/volumes and calculated densities) to ensure traceability and reproducibility.

Note: This summary avoids procedural specifics (temperatures, times, sample counts) that are given in the full EN text.

Practical applications

• Quality control and production monitoring in masonry unit manufacturing.
• Material characterization for structural and thermal design where mass per unit volume affects performance.
• Verification of compliance with product specifications and contractual requirements.
• Input data for structural engineers, architects and energy modelers who require accurate unit densities for calculations (dead loads, thermal mass, acoustics).

Who uses this standard

• Masonry unit manufacturers and production QA/QC teams
• Accredited testing laboratories and inspection bodies
• Structural and geotechnical engineers, architects and specification writers
• Research institutions studying masonry materials and product development
