EVS-EN 14022:2010

This European Standard specifies means of determining in appropriate ways the variable property known alternatively as useable working life and pot life. This European Standard specifies five methods for the determination of the time available for use, each of which is related to specific circumstances; particularly important being the rheology of the adhesive concerned and its rate of reaction. This European Standard can also be used for assessing non-structural adhesives. NOTE  EN 302-7 could also be used for the determination of working life of adhesives for load-bearing timber structures. Because of the different properties of the individual multi-component systems, like rheology or viscosity, respectively velocity of hardening, etc., not all methods can be applied to each multi-component system with the same suitability.
