ISO标准都属于推荐性标准。没有特殊的约定不具备强制性,但是建议尽量采用本标准,因为
第一、从企业自身来说,它代表了国际先进水平(或经验)和最普遍的需求。
第二、从商业经济的角度来说,它是世界化大生产、国际贸易的需要。
关键解读:
1、PW/WFI 预处理和生产系统中的所有部件均应由不锈钢(SS) 316/316L 制造(目前国内基本都用的304不锈钢)
2、对焊应尽可能由轨道焊接机进行,应对70%的自动焊缝进行检查,并对100%的手动焊缝进行内窥镜检查(容易产生歧义,注意只是说了70%的自动焊缝进行检查,并没有要求内窥镜)
3、在整个系统中,无论是非最终PW/WFI 管道还是最终水管道,均应使用零死角取样阀。(目前国内大部分都不是0死角)
4、如果安装了在线电导率仪器,且在线电导率已符合国家规定,则无需取样离线测试电导率。(USP要求电导率检测为三步检测法,故在线无法取代离线检测,否则无法满足FDA。在线只是用于监控,不能作为参数放行数据,为了便于监控还是建议进行温度补偿显示电导率,实验室需要按照药典要求进行无温度补偿的电导率测试用于参数放行的最终数据)
