ISO 11343 Determination of Adhesive Bond Strength Under Impact (wedge-peel test)
Use of structural adhesives has increased as more manufacturers become aware of their advantages compared to conventional joining techniques. The increased use of these adhesives in industry, especially in safety-critical areas, makes it necessary to evaluate any possible decrease in performance when subjected to impacts. Adhesive wedge peel test methods have been developed to evaluate fracture behavior of adhesively bonded joints when subjected to impact. The wedge-peel test is an ISO-standardized test method used to measure the resistance of structural adhesives to cleavage fracture at various speeds and user defined temperatures. The test consists simply of a wedge, driven between two bonded surfaces under impact.
Impact testing to this standard can deliver vital information to aid manufacturers in the research and development of new adhesives. Additionally, an environmental chamber enables the user to test at low and high temperatures, from -70 to -150. Once a suitable product has been established, both manufacturer and end-user can implement a quality control program utilizing baseline data from the impact performance tests to provide ongoing process validation and quality control.
When performing such wedge peel tests, we recommend using the CEAST 9350, with an instrumented tup and specialist striker for ISO 11343. Additionally the Data Acquisition System and Visual Impact software are critical for proper data collection and analysis.
CEAST 9300 Series
Impact resistance is one of the most important properties for component designers to consider, as well as the most difficult to quantify. Impact resistance is a critical measure of service life and more importantly these days, it involves the perplexing problem of product safety and liability. With the combined experience of Dynatup® and CEAST, Instron® has more than 80 years experience in designing impact testing systems to simulate real-life impact conditions.

CEAST Data Acquisition and Analysis
The new CEAST DAS 64K is a state-of-the-art Data Acquisition System designed for impact testing instruments. Compatible with the full range of CEAST impact testing systems, including pendulum type machines (CEAST 9000 Series) and drop towers (CEAST 9300 Series), it’s the key for instrumented impact testing. The DAS 64K also enables the data collection from instrumented tups or hammers on older models and non-CEAST impact machines.
