What is ISO 11343 about?
ISO 11343 specifies a dynamic impact wedge method for the determination of the cleavage resistance under impact loading of high-strength adhesive bonds between two adherents when tested under specified conditions of preparation and testing. This test procedure does not provide design information.
The method described in ISO 11343 allows a choice of sheet metal or fibre reinforced plastic substrates corresponding to those materials frequently used in industry, such as for automotive applications.
Who is ISO 11343 for?
ISO 11343 on adhesives is relevant to:
- Manufacturers of rubbers and adhesives
- Chemical Engineers
- Researchers and scientists
- Any entity responsible for testing adhesives
Why should you use ISO 11343?
An adhesive, also known as glue, cement, mucilage, or paste, is a non-metallic substance that can bind together two items and prevent their separation.
ISO 11343 specifies techniques to determine the average cleavage resistance, expressed as force and energy, of an adhesive bond between two adherents. The cleavage occurs when a wedge travels at high speed, separating the adherents.
Overall, ISO 11343 is a comprehensive guide to determine the resistance of high strength adhesive bonds, so users will gain a comprehensive understanding of the process and the end product will be safer, more durable and more environmentally friendly.
