TIGER Wall Ties – Conformity Assessment
This page summarises the independent testing carried out by Lucideon Limited (Notified Body No. 1289) on the TIGER Starter Tie 50. Testing was performed in accordance with BS EN 846‑6:2012, the standard for determining the tensile and compressive load capacity of wall ties.
Test Overview
The TIGER Starter Tie 50 was tested by Lucideon on 2 July 2020. The report states that testing was performed:
“in accordance with BS EN 846‑6:2012 … Determination of tensile and compressive load capacity and load displacement characteristics of wall ties.”
The tie tested is the same design used in TIGER Starter and Cavity Wall Ties:
- Triangular stainless‑steel embedment end
- Screwed end with 25 mm EPDM sleeve between two M4 nuts
- Asymmetrical design compliant with BS EN 845‑1
Installation Method Used in Testing
Lucideon installed the ties using the same procedure described in the TIGER Installation Guide:
- 8 mm drill bit
- 40 mm embedment depth
- EPDM sleeve lightly tightened (“nuts just making contact with the EPDM”)
- Tie twisted into the hole until finger tight
This alignment between test method and installation procedure ensures that the published performance values accurately reflect real‑world use.
Performance Results
Lucideon tested ten specimens in tension and ten in compression. The key results are summarised below.
Tension (Pull‑Out)
- Mean load capacity: 2960 N
- Lowest individual value: 2590 N
- Mean displacement at 1/3 load: 0.63 mm
- Typical failure mode: Withdrawal of tie from hole
Compression (Push‑In)
- Mean load capacity: 2180 N
- Lowest individual value: 1840 N
- Mean displacement at 1/3 load: 0.44 mm
- Typical failure mode: Bending of tie
Test Requirements of BS EN 846‑6
BS EN 846‑6:2012 is a test method standard. It does not specify minimum required load capacities, but it does define how wall ties must be tested and how manufacturers must declare performance. Declared tensile and compressive values must satisfy the following conditions:
- The mean load capacity must exceed the declared value.
- No individual test result may be less than 70% of the declared value.
- The mean displacement at one‑third of the declared value must be stated.
These criteria ensure that declared performance values are statistically reliable and conservative. The Lucideon results for the TIGER Starter Tie 50 meet all three requirements.
Declared Performance
Based on the Lucideon test results, the following characteristic values may be safely declared:
- Tension: 2590 N (lowest individual result)
- Compression: 1840 N (lowest individual result)
These declared values comply fully with the requirements of BS EN 846‑6:2012.
Summary
Independent testing confirms that TIGER Starter Tie 50 wall ties deliver strong, consistent performance in both tension and compression. The installation method used in testing matches the official TIGER Installation Guide, ensuring that the declared values reflect real‑world use.
