Sec. 159.107  Rolling test.

    (a) The device, with liquid retention components, if any, filled 
with water to half of their volume, must be subjected to 100 cycles with 
the axis of rotation 4 feet from the centerline of the device, no more 
than 6 inches below the plane of the bottom of the device, and parallel 
to any tank baffles. The device must then be rotated 90 degrees on its 
vertical axis and subjected to another 100 cycles. This testing must be 
repeated with the liquid retention components filled to the maximum 
operating level as specified by the manufacturer in Sec. 159.57.
    (b) Eighty percent of the rolling action must be approximately 15 
degrees on either side of the vertical and at a cyclic rate of 3 to 4 
seconds. Twenty percent motions must be approximately 30 degrees, or the 
maximum angle specified by the manufacturer under Sec. 159.57, whichever 
is greater, on either side of the vertical at a cyclic rate of 6 to 8 
seconds.
