Standard: BS EN 14869 Structural adhesives – Determination of shear behaviour of structural bonds – Part 1: Thin and thick adherends using butt joints.

BS EN 14869 specifies a test method for determining the shear behaviour of structural bonds, covering both thin and thick adherends using butt joints. This standard is significant for evaluating the performance of structural adhesives in applications where resistance to shearing forces is paramount. It provides methodologies for assessing how an adhesive bond performs when subjected to forces acting parallel to the bonded interface. The test typically involves preparing butt joints (where adherends are joined end-to-end) and then subjecting them to shear loading until failure. This allows for the determination of the shear strength of the bond, providing critical data for the design and qualification of structural adhesive joints. Understanding the shear behaviour is essential for ensuring the integrity of bonded assemblies in various industries, from construction to manufacturing.

Clients Reviews
4ward Testing performed with a high degree of professionalism, care and attention to detail throughout.
The testing that 4ward carried out was of a high standard, met deadlines and targets that were necessary and we were kept involved with regular updates as the testing progressed. The support and guidance that 4ward offered to us as an individual company and via their input to BASA was greatly received and helped the industry increase it’s knowledge of what is still a confusing issue. I’m sure that that the issue of CE Marking will continue to evolve and encompass more products, but it is our intention to continue to use 4ward for our CE Marking requirements whether for new product development or where new Harmonized Standards emerge.

We had a requirement to test a sample of a large stock of face masks, to ensure their suitability for use by those supporting the response to the “COVID pandemic”.  4ward Testing were recommended to us and they delivered their report well within the agreed timescale. I was impressed with their recognition of the urgency this work required and communications with Polly & Anthony were excellent so I would have no hesitation in using their services again, or in recommending them to others!
NHS Services Scotland
The level of service received from the team at 4ward Testing was excellent. We have no hesitation in recommending 4ward Testing and will use again when the need arises.
4ward reacted very quickly, delivered on time and were very communicative during the process, and were efficient in the follow up. We have continued to work with them and expect to do so.
4ward Testing have worked closely with Canusa and our client on all aspects of the work undertaken. Their wide experience, coupled with an in-depth knowledge of international specifications and standards, has helped speed the testing process considerably and their professional, authoritative and confident testing skills have allowed us to arrange witnessed tests, giving our clients even greater assurance of true independence – tangible benefits of the 4ward Testing philosophy of intelligent testing. We would have no hesitation in recommending 4ward Testing, as they have proven to be a modern, professional an progressive testing laboratory with a refreshing mix of academic and practical skills so essential for today’s fast moving business environment.
