BS EN 14022:2010 pdf download.Structural adhesives- Determination of the pot life (working life) of multicomponent adhesives.
BS EN 14022 specifies means of determining in appropriate ways the variable properly known alternatively as useable working life and pot life
This European Standard specifies frye 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 cotid also be used for the determination 01 working life of adhesives for load.beanng timber structures
Because of the different properties of me individual multi-component systems. Ike rheology or viscosity, respectively velocity of hardening. etc. not all methods can be applied to each multi-component system witti the same suitability
