Prior to the treatment, a test was carried out using an American Slip Meter, Model No.

It was also intended that the ASTM Horizontal Pull Slip Meter test method be adopted, but, after a comparison of 7 static friction testers, it now appears that this test method must be modified to include a calibration procedure.

So Mr. Hermand is constantly on the move, a short figure dressed in black, with a Chicago Bulls cap and headphones he uses to listen to Diana Ross as he runs up and down the street slipping meter receipts under the windshield wipers just before the ticketers get there.
