Accelerated Polishing Machine (PSV)

The Polished Stone Value (PSV) of a material used as road surfacing is a measure of how rapidly it becomes polished under the action of vehicle tires. The Accelerated Polishing Machine (PSV) is used to accelerate polishing of stone chipping set onto the periphery of a special revolving wheel — all according to the specified Standards. After the cycle, involving two grades of emery powder, the polished specimens are tested on the skid tester (see links below) which gives the PSV, Polished Stone Value.

There anyone who loves or pursues or desires to obtain pain itself, because it is pain sed, because occasionally circumstances occur some great pleasure.
