Methods of test for masonry - Part 4: Determination of shear strength including damp proof course

This European Standard specifies a method for determining the in plane shear strength of horizontal bed joints in masonry incorporating sheet damp proof course material using a specimen tested in double shear with load applied perpendicular to the bed joints. Guidance is given on the preparation of the specimens, the conditioning required before testing, the testing machine, the method of test, the method of calculation and the contents of the test report.

Prüfverfahren für Mauerwerk - Teil 4: Bestimmung der Scherfestigkeit bei einer Feuchtesperrschicht

Diese Europäische Norm legt ein Verfahren zur Bestimmung der in der Tragwerksebene wirkenden Scherfestigkeit von horizontalen Lagerfugen in Mauerwerk mit Feuchtesperrschicht fest; dabei wird ein Prüfkörper verwendet, der auf zweischnittiges Abscheren mit einer rechtwinklig zu den Lagerfugen aufgebrachten Last geprüft wird. Es werden Anleitungen zur Vorbereitung der Prüfkörper, zu der erforderlichen Konditionierung vor der Prüfung, zur Prüfeinrichtung, zum Prüfverfahren, zum Berechnungsverfahren und zum Inhalt des Prüfberichtes gegeben.

Méthodes d'essai de la maçonnerie - Partie 4: Détermination de la résistance au cisaillement, en tenant compte de la couche de coupure de capillarité

La présente norme européenne décrit une méthode de détermination de la résistance au cisaillement dans le plan de joints d'assises horizontaux dans la mançonnerie, y compris les matériaux d'étanchéité à l'aide d'une éprouvette soumise à essai en double cisaillement avec une charge appliquée perpendiculairement aux joints d'assise. Des indications sont données sur la préparation des éprouvettes, le conditionnement nécessaire avant l'essai, la machine d'essai, la méthode d'essai, la méthode de calcul et le contenu du rapport d'essai.

Overview

EN 1052-4:2000 (CEN) defines a standardized test method for determining the in-plane shear strength of horizontal bed joints in masonry that incorporate a sheet damp proof course (DPC). The method uses a specimen loaded in double shear with the load applied perpendicular to the bed joints. The standard covers specimen preparation, conditioning, test equipment, test procedure, calculation rules and required contents of the test report. National adoption (for example SIST EN 1052-4:2002) reflects its use across Europe.

Key topics and requirements

• Scope and applicability
  • Test applies to masonry bed joints containing sheet damp proof course material and aims to measure shear resistance along the joint plane.
• Specimen preparation
  • Requirements for specimen geometry and construction so results are reproducible and comparable.
• Conditioning before testing
  • Controlled conditioning of specimens (e.g., moisture/environment) to reflect realistic test conditions.
• Test machine and loading
  • Use of a suitable testing machine; load applied perpendicular to bed joints in a double-shear arrangement.
• Test method and measurement
  • Step-by-step procedures for applying load, recording shear displacement and failure modes.
• Calculation and reporting
  • Defined calculation formulas for shear strength and detailed content required in the test report (test conditions, specimen data, results and observations).

Practical applications

• Structural design and verification
  • Engineers use EN 1052-4 test results to assess shear capacity of masonry joints where DPC materials are included, informing safe design and structural assessments.
• Product evaluation
  • Manufacturers of masonry materials, mortars and damp proof courses use the standard to demonstrate performance and compliance.
• Quality control and certification
  • Test laboratories and certification bodies apply the method for routine quality testing and product approval.
• Forensic and research use
  • Researchers and failure investigators use standardized shear tests to compare materials, joint treatments and construction techniques.

Who should use this standard

• Structural and geotechnical engineers
• Masonry product manufacturers and suppliers
• Construction material testing laboratories
• Certification and conformity assessment bodies
• Academic and R&D teams studying masonry behavior

Related standards

• Other parts of the EN 1052 series (masonry test methods) and national adoptions (e.g., SIST EN 1052-4:2002) should be consulted for complementary test methods and broader masonry testing practice.
