ISO 11897
ISO 11897 is an internationally recognized test method that determines the peel strength of adhesive joints using a floating roller peel method. The standard is appropriate to measure the bonding strength between two dissimilar materials, one flexible and the other rigid, that are joined together with adhesives. In the test, the flexible adherend is pulled from the rigid substrate by a controlled force and by having a floating roller to minimize other forces that might affect the result. It is a standard practice used in many of the industries in which adhesive bonding is a key element, including packaging, automotive, aerospace, electronics, and construction. Presto Stantest provides cutting-edge testing services to evaluate adhesive performance, meeting ISO 11897 requirements.
Significance
Peel strength is one of the significant parameters to assess the quality and durability of adhesive bonds. The adhesion of products when exposed to mechanical stress, temperature change, vibration, and handling must be strong and consistent. ISO 11897 assists manufacturers to compare adhesive systems and production quality control as well as material compatibility. Test results can be used to guide product development, quality assurance, and research, serving as useful data for bond integrity. If the poor bonding can be identified early, then the amount of failure can also be minimized, and the assembly and the packaging performance improved by the manufacturers. Scope ISO 11897 details the floating roller peel test procedure, which is used for assessing peel resistance of adhesive bonded assemblies. The standard can be used for flexible materials adhered to rigid substrates by a number of different adhesive systems. It defines specimen preparation, testing conditions, and force measurement procedures to obtain consistent and repeatable results. The method allows manufacturers to compare adhesive bond performance under controlled laboratory conditions and assess the suitability of materials for intended applications.
