vibrate the packaged product (master carton) for a total of 14,200 vibratory impacts. (The total duration of test time in minutes to meet this requirement is determined by dividing 14,200 by the RPM set in accordance with 4.1.3 above). A single 90 degree horizontal rotation should be performed after one-half of the vibration time has been accomplished. If a single 90 degree horizontal rotation is impractical because of the size of the packaged product (master carton), a 180 degree horizontal rotation will be permissible.
