Overview
EN 1741:1998 is a CEN (European) standard that specifies a laboratory method for determining the shear strength under out‑of‑plane forces of joints between prefabricated elements made of autoclaved aerated concrete (AAC) or lightweight aggregate concrete with open structure (LAC). The standard applies to joints of components manufactured according to prEN 12602 (AAC) or prEN 1520 (LAC) and provides a repeatable test procedure to assess how joints behave when loads act perpendicular to the element plane.
Key topics and requirements
- Scope and applicability: Defines the materials and types of prefabricated components covered (AAC and LAC) and the specific joint condition-forces acting out of the plane of the elements.
- Test method: Describes specimen preparation, test arrangement and instrumentation needed to measure shear resistance of joints under out‑of‑plane loading (general procedural requirements rather than numeric design values).
- Measurement and reporting: Requires documentation of test conditions, observed failure modes, measured shear capacity and any relevant material or joint characteristics that affect results.
- Reproducibility and safety: Emphasizes consistent specimen preparation and test execution so results can be compared across laboratories and products.
- Material references: Links test application to component standards referenced in the scope (prEN 12602 for AAC and prEN 1520 for LAC).
Practical applications
- Product qualification: Manufacturers of AAC and LAC prefabricated components use EN 1741:1998 to demonstrate joint performance for product datasheets and CE marking processes.
- Design verification: Structural and façade engineers rely on measured shear strength of joints to validate connection details and ensure out‑of‑plane stability of panelized systems.
- Quality control and R&D: Testing laboratories and factory quality teams use the method for batch verification, troubleshooting, and development of improved joint solutions (mortar types, connectors, joint geometry).
- Safety assessment: Building inspectors and consultants apply test results when assessing retrofit, re‑use, or atypical loading conditions (wind uplift, impact) that impose perpendicular forces on joints.
Who should use this standard
- Structural engineers, façade and precast designers
- Manufacturers of AAC and LAC prefabricated components
- Third‑party testing laboratories and certification bodies
- Construction quality managers and product R&D teams
