What is BS EN 15190 - Structural adhesives about?
BS EN 15190 specifies test procedures for determining the long-term durability of an adhesive system subjected to environmental and fatigue loads. The procedures are based upon measurement of the crack growth rate and the resistance to crack propagation through the adhesive layer in double cantilever beam type specimens under an applied mode I opening cycling loading.
The test method has been proven to be particularly sensitive in finding weaknesses within certain adhesive systems and is recommended as a scientific tool to study adhesion properties. This test method may be used to determine:
- The fatigue crack growth rate as a function of the mode I strain energy release rate;
- The threshold values for negligible crack growth;
- The effects of other environmental factors (temperature and/or humidity cycling);
- The mode I (peel or crack opening) failure mode of the adhesive joint (cohesive, interfacial, near-surface …).

Why should you use BS EN 15190 - Structural adhesives? 
Susceptibility to fatigue crack growth under hot humid conditions is one of the major concerns for the durability assessment of bonded metallic joints. Knowledge of the long-term durability of bonded joints is useful for product development and material selection.
BS EN 15190 provides different procedures and methods for assessing long term durability of bonded metallic structures.
BS EN 15190 provides you with apparatus, sampling, transport, storage, and preparation of test pieces, preparation of reagents and apparatus, pre-treatment of test pieces, test procedure, and much more.
The specifications given in BS EN 15190 enable you to standardize the quality of adhesives which contributes a lot to maintaining the high quality and efficient functioning.
