For the purposes of simplification, the term pot life is deemed to have the same meaning as working life and will be used to represent both throughout this International Standard. Methods described to measure the property provide different answers. So the results shall be specified with respect to the method used.
The test methods described are suitable for assessing all multi?part adhesives, and especially epoxy based and polyurethane based adhesives, but they are not suitable for some acrylic-based adhesives.
NOTE 1 Some of the methods described in this International Standard can also be suitable for determination of working life of one-part adhesives that react to humidity (e.g. PUR prepolymers).
NOTE 2 This International Standard can also be used for assessing non-structural adhesives.
