FDA does not intend to set acceptance specifications or methods for determining whether a cleaning process is validated. It is impractical for FDA to do so due to the wide variation in equipment and products used throughout the bulk and finished dosage form industries. The firm's rationale for the residue limits established should be logical based on the manufacturer's knowledge of the materials involved and be practical, achievable, and verifiable.
“FDA不打算为清洁验证设定一个通用方法或限度标准。那是不切实际的,因为原料和制剂生产企业使用的设备和生产的产品千差万别,确立残留物限度不仅必须对所有有关物质有足够的了解,而且所定的限度必须是现实的、能达到和可被验证的。”
