EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of DIN 54457 testing. This standard specifies a method for assessing the adhesion of elastic adhesives with a minimum elongation at break of 100% and a maximum modulus of elasticity of 10 MPa on various substrates.
In this way, the effect of different coatings or surface pretreatments of bonding materials on adhesion can be compared. It can also be used to evaluate the effect of the adhesive or substrate on the long-term durability of the bond. An adhesion test according to this standard may also be recommended for process control accompanying production.
DIN 54457 is a German industry standard that describes a test method for evaluating the bond strength of structural adhesives in bonded joints using a bead peel test. The test is designed to determine the adhesive's ability to provide a strong bond between two surfaces under tensile load.
The test involves applying a bead of adhesive to one of two metal substrates, which are then clamped together and left to cure for a certain period of time. After curing, the bonded substrates are placed in a tensile testing machine and a tensile load is applied to the bonded area in the direction perpendicular to the bond line. The force required to pull the adhesive beads from the substrate is measured and this value is used to determine the strength of the bond.
The results of the bead peel test can be used to compare the performance of different adhesive formulations and to ensure that a particular adhesive is suitable for a particular application. This test is particularly useful for evaluating adhesives used in structural applications such as building or bridge construction where the strength of the bond is critical to the performance and safety of the structure.
It is important to note that the bead peel test is a useful tool in evaluating adhesive performance, but it is not the only test that should be used. Other factors such as environmental conditions, surface preparation and method of application can also affect the performance of an adhesive bond. Therefore, it is important to consider all relevant factors when selecting and testing adhesives for structural applications.
