General Test Methods
 

• Clean the inclined trough and ball with n-heptane or methyl alcohol.
• Do not touch the trough or ball with fingers after cleaning.
• Cut a 15" long (380mm) by 2" wide (50mm) specimen for testing purposes.
• Arrange the test specimen at the end of the device, adhesive side up, in a straight line with the trough. The bottom of the device should hold downthe leading end of the specimen and a weight or other tape should hold the other end securely.
• Ensure the device is level and aligned with the trough axis. 
• Use a lint free cloth to place the ball at the top of the inclined trough for testing. 
• Press the spring lever and allow the ball to roll down the trough.
• Measure the distance between the end of the incline and the point where the ball stops.
