Overview

EN 772-9:1998/A1:2005 is Part 9 of the CEN series "Methods of test for masonry units". It specifies a test method for the determination of volume, percentage of voids and net volume of clay and calcium silicate masonry units by sand filling. The 2005 amendment (A1) updates the original 1998 text (title, scope, normative references, sampling and test-report wording) and confirms the standard’s role in harmonized European masonry testing.

Key topics and requirements

• Scope: Applies to clay (fired) and calcium silicate masonry units; defines the sand-filling approach to quantify total volume, void volume (percentage of holes/cores) and resulting net volume.
• Test principle: Uses sand filling to occupy open voids/cores so that the void volume can be calculated relative to the unit’s gross volume (high-level method description; procedural specifics are in the standard text).
• Sampling: References the relevant Part(s) of EN 771 for sampling requirements (amendment replaces earlier prEN references with the appropriate EN 771 part).
• Test report: Requires identification of the test method, sampling reference, measured volumes, calculated percentage voids and any deviations; amendment clarifies cross-references to EN 771.
• Normative references: Cross-references other masonry product and test standards (EN 771 series and EN 772 series such as EN 772-16 for dimensions).

Practical applications

• Quality control and factory production control for masonry units (clay bricks, calcium silicate blocks).
• Product classification and compliance testing where void content, net volume or unit porosity affect mechanical properties, thermal performance, mortar consumption and overall masonry design.
• Use by: manufacturers, third-party testing laboratories, building product certifiers, construction materials engineers and specification authors who need standardized, repeatable methods for measuring voids by sand filling.
• Regulatory and contractual conformity: supports declarations of performance and harmonized technical documentation under European construction product rules.

Related standards

• EN 772 series - Methods of test for masonry units (other parts cover density, strength, dimensions, absorption).
• EN 771-1 / EN 771-2 / EN 771-4 - Product standards for various masonry units; referenced for sampling and product identification.
• EN 772-16 - Determination of dimensions (title updated in amendment).

This standard is published by CEN (Technical Committee CEN/TC 125 "Masonry") and implemented by national bodies. Keywords: EN 772-9, masonry units, sand filling, voids percentage, net volume, clay masonry, calcium silicate, masonry testing, test method.
