Overview

EN 772-10:1999 - Methods of test for masonry units, Part 10 - specifies a standardized procedure for determining the moisture content of calcium silicate and autoclaved aerated concrete (AAC) masonry units. Published by CEN in 1999, this European Standard provides a consistent approach for assessing moisture levels in these masonry products to support product quality, performance evaluation and regulatory compliance.

Keywords: EN 772-10, moisture content, calcium silicate, autoclaved aerated concrete, AAC, masonry units, CEN, masonry testing

Key Topics

The standard focuses on the essential elements required to produce reliable, repeatable moisture measurements for masonry units. Key technical topics and requirements include:

• Scope and applicability - defines which masonry unit types (calcium silicate and AAC) and conditions are covered.
• Sampling and specimen selection - guidance on selecting representative samples from production batches or deliveries.
• Specimen preparation and conditioning - instructions to prepare test specimens to a defined state before measurement.
• Measurement procedure - a standardized test sequence to determine moisture content and reduce variability between laboratories.
• Equipment and accuracy - specification of suitable test equipment and practices to ensure reliable results.
• Calculation and expression of results - how moisture content is calculated, recorded and reported to ensure clarity and comparability.
• Test reporting and documentation - minimum information to include in test reports for traceability and QA.

(EN 772-10 establishes procedural controls rather than product performance limits; users should refer to product standards or specifications for acceptance criteria.)

Applications

EN 772-10 is practical for organizations and professionals involved in the manufacture, testing, specification and use of calcium silicate and AAC masonry units:

• Masonry product manufacturers - quality control during production and before shipment.
• Independent testing laboratories - routine testing and certification services.
• Specifiers, architects and structural engineers - verifying material condition for design assumptions (durability, thermal performance).
• Construction contractors and site QA teams - acceptance testing on delivery and prior to installation.
• Research and development - comparing material treatments, curing regimes or storage effects on moisture behaviour.

Accurate moisture determination helps manage drying/storage, assess risk of frost damage or efflorescence, and improve thermal and hygrothermal performance predictions.

Related Standards

• Other parts of the EN 772 series (Methods of test for masonry units) - for complementary test methods relevant to masonry product assessment.
• Product standards and national implementations based on CEN documents for compliance and performance criteria.
