Drained weight is controlled through control of the fill weight but cannot be evaluated until after the thermal process. If drained weight is found to be out of limits, it may involve the entire lot. In that event evaluation by a processing authority for commercial sterility ('minimum health process'), or destruction of the lot may be the only options available to the firm. Drained weights are also specified for meeting quality standards. The drained weights for quality/fill of containers standards should not be confused with the fill weights used to determine thermal processes for those products
