Methods of test for ancillary components for masonry - Part 6: Determination of tensile and compressive load capacity and load displacement characteristics of wall ties (single end test)

This European Standard specifies a method for determining the tensile and compressive load capacity and load displacement characteristics of wall ties screwed, nailed, grouted or otherwise attached to frame elements or to inner leaf materials. The test is intended for ties for connecting masonry leaves to frame structures and to the inner leaves of cavity walls other than by embedding the inner connection in a mortar joint.

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
patent rights.
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,
Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of
Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania,
Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain,
Sweden, Switzerland, Turkey and the United Kingdom.
1 Scope
This European Standard specifies a method for determining the tensile and compressive load
capacity and load displacement characteristics of wall ties screwed, nailed, grouted or otherwise
attached to frame elements or to inner leaf materials. The test is intended for ties for connecting
masonry leaves to frame structures and to the inner leaves of cavity walls other than by embedding
the inner connection in a mortar joint.

The tie is screwed, nailed, grouted or attached using other devices such as keys in slots, to a
representative section of the frame element or inner leaf material using normal site techniques. The
tie is then subjected to tension or compression until failure occurs.
