8 Expression of results
9 Test report

Defines means of determining in appropriate ways the variable property known alternatively as useable working life and pot life. It also defines 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.
