Manufacturing Equipment Grouping

Companies may choose to selectively perform cleaning validation studies on representative groups
of equipment.

For equipment groupings, form and function define the criteria for the grouping
philosophies.

Equipment which is similar in design and function, perhaps differing only in scale, may
appropriately be grouped when performing validation testing.

Throughout the validation studies,
however, scientific principles must be followed.

The cleaning method may be validated on the largest
and smallest scale equipment within the grouping if the same cleaning procedures are to be
implemented.
