A campaign is a series of batches of the same product manufactured one after the other. Consideration should be given to the need to clean, and the extent of cleaning, between batches in a campaign.Depending on the product, there may be no cleaning between batches or some level of cleaning is done between batches. If the cleaning between batches is simply a vacuuming (for solid products)or a solvent or water rinse (for liquid products), such cleaning is sometimes called “minor” cleaning or “in -process” cleaning. Such minor or in -process cleaning steps do not require separate validation.However, consideration should be given to the effect of such minor or in -process cleaning steps on the efficiency of the “full ” cleaning process done at the end of a campaign for changeover to a newproduct or campaign.
请问按照原文理解,什么时候不进行“批间清洁”???还有就是如何评价“批间小清”和“工艺内清洁”对转产其他产品的“全面清洁”的影响呢??? |
