6.1.5. Foam Height: Measure as follows:
126.96.36.199. Take 10.0 ml of the 1.0% solution used for the pH test, dilute with dionized water to 50.0 ml, and transfer to a 250 ml graduated cylinder.
188.8.131.52. Stopper the cylinder and shake by inversion, rotating the cylinder about its midpoint without transitional motion for one minute at such a rate that 30 inversions are completed.
184.108.40.206. Place the cylinder in an upright position upon a rigid surface, remove the stopper, wait five seconds and read the net volume of foam (total volume minus the volume of the liquid).
220.127.116.11. Determine compliance with Table 2.
