Overview
EN 846-6:2012 (CEN) - Methods of test for ancillary components for masonry, Part 6 - specifies a single end test to determine the tensile and compressive load capacity and load–displacement characteristics of wall ties. It covers ties that are screwed, nailed, grouted or otherwise attached to frame elements or to inner leaf materials (not by embedding the inner end in a mortar joint). The standard is intended for assessing ties used to connect masonry leaves to frame structures and inner leaves of cavity walls.
Key topics and requirements
- Test principle: The tie is fixed to a representative section of the frame or inner leaf and loaded in tension or compression until failure; displacement is recorded to produce load–displacement curves.
- Specimen numbers and preparation: Ten specimens are required for tension and ten for compression at the declared minimum embedment length; numbers double if both asymmetric ends are tested.
- Materials & conditioning: Timber studs per EN 338 (strength class C24, density ≤ 600 kg/m³, moisture 9–15%), OSB sheathing per EN 300 (typically 400 ±10 mm square, ≥ 8 mm thick), representative metal or concrete elements, masonry units per EN 771 and conditioning per EN 772 series.
- Apparatus & measurement: Rigid support avoiding restraint within 2× embedment depth or 100 mm; clamps for tie ends; load cell with max 2% full-scale error; displacement measurement to 0.01 mm using symmetrical dial gauges or LVDTs.
- Special cases: For slope- or movement-tolerant ties, specimens are cycled 50 times through the design movement prior to test. Slot-type anchors require concrete to EN 206-1 (minimum class C20/25).
- Reporting: Test report must include specimen details, embedment, conditioning, failure mode and load–displacement data.
Applications and who uses this standard
EN 846-6:2012 is used to:
- Verify performance of wall ties in product development and type testing
- Provide data for designers and structural engineers assessing tie suitability
- Support product certification, compliance with ancillary component specifications
- Guide test laboratories, manufacturers, contractors and building authorities in reproducible single-end loading tests for masonry ties
Typical users: tie manufacturers, independent test houses, masonry product certifiers, structural engineers, building control bodies and contractors specifying tie performance.

Foreword
This document (EN 846-6:2012) has been prepared by Technical Committee CEN/TC 125 “Masonry”,
the secretariat of which is held by BSI.
This European Standard shall be given the status of a national standard, either by publication of an
identical text or by endorsement, at the latest by February 2013, and conflicting national standards
shall be withdrawn at the latest by February 2013.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such

This document supersedes EN 846-6:2000.
The principal changes in this document form the previous edition relate to the number of ties to be
tested, the location of the clamp during testing and the treatment of slope and movement tolerant ties.
Ties are to now be placed at the minimum declared embedment length rather than a length calculated
from the tie length and design cavity width. Ten ties are tested in tension and ten in compression. In
the compression tests the ties are loaded over an extended cavity, or alternatively provision is made
for evaluating the cavity section by calculation. Where ties are designed to tolerate either an induced
slope or movement then prior to test they are cycled fifty times through the slope or movement for
which they have been designed.
According to the CEN/CENELEC Internal Regulations, the national standards organisations of the
following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria,

Sa conformité aux normes européennes stimule également la confiance des utilisateurs et des professionnels du secteur, car elle est en ligne avec les attentes réglementaires et normatives en matière de sécurité des constructions. En somme, EN 846-6:2012 représente une pierre angulaire pour les ingénieurs et les concepteurs de systèmes de maçonnerie, facilitant la mise en œuvre de solutions structurales fiables et performantes.
The standard EN 846-6:2012 provides a comprehensive methodology for testing ancillary components specifically for masonry wall ties. One of its primary strengths lies in its detailed examination of both tensile and compressive load capacities, as well as load displacement characteristics of wall ties. This ensures that the standard covers essential aspects that affect the structural integrity of masonry constructions involving frame elements and inner leaf materials. The scope of the standard is particularly noteworthy. It defines a clear and methodical approach for assessing ties that are fixed to masonry through multiple attachment methods, including screwing, nailing, and grouting. Furthermore, it emphasizes connections that are critical for the stability of masonry leaves to frame structures, thereby ensuring relevance in modern construction applications where these connections often dictate overall building performance. Another significant aspect is the focus on single end tests, which simplifies the testing process while providing reliable data on how these wall ties perform under various loads. The standard effectively addresses potential failures in connecting masonry to frame elements, making it relevant for engineers and builders concerned with ensuring the safety and durability of masonry structures. In summary, EN 846-6:2012 is a robust and effective standard, crucial for understanding the performance characteristics of wall ties used in masonry. Its detailed testing methodology and focus on practical applications reinforce its relevance in contemporary masonry construction practices. The standard serves as an essential tool for manufacturers and construction professionals dedicated to enhancing the safety and reliability of masonry connections.
SIST EN 846-6:2012 표준은 벽체 연결용 벽 타이의 인장 및 압축 하중 용량과 하중 변위 특성을 측정하는 방법을 규정하고 있습니다. 이 표준이 제시하는 테스트 방법은 프레임 요소 또는 내벽 자재에 나사, 못, 치환하거나 기타 방법으로 부착된 벽 타이에 대한 것으로, 특히 조적 구조의 잎사귀를 프레임 구조와 연결하고, 공극 벽의 내벽과 연결하는 역할을 합니다. 이 표준의 강점 중 하나는 다양한 부착 방식에 대해 적용할 수 있는 테스트 방법을 제공한다는 것입니다. 이를 통해 벽 타이가 프레임이나 내벽 자재와 어떻게 연결되는지를 효과적으로 평가할 수 있으며, 각기 다른 건축 상황에서의 성능을 비교할 수 있는 기초 자료를 제공합니다. 덧붙여, EN 846-6:2012 표준은 조적 구조에서 벽 타이의 신뢰성을 높이는 데 기여하며, 이로 인해 건축의 안전성을 강화하는 데도 필수적인 역할을 합니다. 이러한 점에서 이 표준은 건축 자재 및 구조 설계 분야에서 매우 중요하며, 벽 타이에 대한 명확한 측정 기준을 통해 품질 보증 및 규정 준수를 촉진합니다. 결론적으로, SIST EN 846-6:2012 표준은 벽 타이에 대한 테스트 방법을 체계적으로 규명하고 있어, 건축 분야의 전문가들에게 실질적이고 유용한 정보를 제공합니다. 이 표준의 적용은 섬세한 조정과 개선을 통해 더욱 안전하고 효율적인 건축 작업을 가능하게하는 핵심 요소로 작용합니다.
SIST EN 846-6:2012は、壁タイの引張および圧縮荷重能力、荷重変位特性を測定するための方法を規定した重要な標準です。この標準は、フレーム要素や内壁材料への取り付け方法に関する検証を行うための基準を提供しており、特にレンガ造りやコンクリート製の壁における構造的整合性を確保するために不可欠です。 この標準の強みは、その適用範囲にあります。壁タイは、モルタルジョイントに埋め込むことなく、レンガ葉をフレーム構造やキャビティウォールの内葉に接続するために重要な役割を果たします。このため、EN 846-6:2012は、壁タイの利用目的や特性を包括的に評価するための信頼できるフレームワークを提供しています。 さらに、この標準は、試験方法を明確に定めることで、異なる設計や材料における一貫性を促進しています。これにより、建築業界における安全性や耐久性に対する信頼を高め、新技術や新材料の開発に対する指針をも提供します。特に、壁タイの強度特性を評価することができるため、設計者やエンジニアは、より高い安全基準を遵守し、最適な施工方法を選択する上での重要な情報を得ることができます。 以上のように、SIST EN 846-6:2012は、壁タイの評価において重要なアプローチを提供し、建築構造物の信頼性を強化するための標準的な手段としての役割を担っています。
Der Standard SIST EN 846-6:2012 bietet eine umfassende Methode zur Prüfung der Zug- und Drucktragfähigkeit sowie der Verformungseigenschaften von Mauerwerksankern, die zur Verbindung von Mauerwerksblättern mit Rahmenkonstruktionen oder inneren Blättern von Hohlwänden eingesetzt werden. Dieser Standard ist von großer Bedeutung für die Bauindustrie, da er sicherstellt, dass die verwendeten Bauteile den erforderlichen strukturellen Anforderungen genügen. Die Stärken des Standards liegen in seiner klaren Definition der Prüfmethoden, die sowohl für die Befestigung mittels Schrauben, Nägeln als auch durch Verfugung gelten.
