1.1This test method covers a laboratory procedure for determining the no-pick-up time of a traffic paint. The method uses a wheel consisting of a metal cylinder with rubber O-rings. The wheel is rolled down a ramp over a freshly applied traffic paint film repeatedly until there is no transfer of paint to the rubber rings. The elapsed time from paint film application to point of no paint transfer is the no-pick-up time. Key variables to be controlled during testing are film thickness, temperature, humidity, and air flow.
