SIST EN 1052-1:1999

Overview

EN 1052-1:1998 - Methods of test for masonry - Part 1: Determination of compressive strength - specifies a standardized procedure for measuring the compressive strength of masonry. The standard gives guidance on specimen preparation, conditioning prior to testing, the required testing machine and setup, the step‑by‑step test method, calculation of results and the content of the test report. EN 1052-1 is used to produce repeatable, comparable compressive strength data for masonry assemblies and elements.

Key topics and requirements

The standard addresses the principal technical topics needed to carry out reliable masonry compression tests:

• Specimen preparation: requirements for sampling, dimensions and how to cut or extract representative test specimens from masonry assemblies.
• Conditioning: guidance on environmental conditioning and moisture state prior to testing to ensure consistent test conditions.
• Testing equipment: characteristics and calibration of the compression testing machine, platens and alignment devices required to apply axial load uniformly.
• Test procedure: the stepwise method to apply load, monitor deformation and record failure; emphasis on preventing eccentric loading and ensuring repeatability.
• Calculation method: how to determine compressive strength from measured load and specimen dimensions and how to interpret results.
• Test report content: required documentation such as specimen identification, conditioning history, test setup, peak loads, failure mode descriptions and any deviations from the standard procedure.

Applications

EN 1052-1 is applicable in contexts where reliable compressive strength data for masonry is required:

• Quality control and factory/field testing of masonry walls and blocks
• Verification of masonry performance for repair, refurbishment or change-of-use projects
• Research and development of masonry materials and systems
• Compliance testing to support structural design checks and certification

Who uses this standard

• Structural and geotechnical engineers assessing masonry capacity
• Materials and construction testing laboratories performing accredited tests
• Architects and contractors specifying and verifying masonry performance
• Manufacturers of masonry units and mortars engaged in product development and quality assurance
• Regulators and certification bodies requiring documented test evidence

Related standards

• Other parts of the EN 1052 series (masonry test methods)
• Design standards for masonry (for example, Eurocode 6 / EN 1996) and material standards for masonry units and mortar (used in conjunction with compressive strength results)
