首先应该了解几个英文单词: Clean/ Cleaning:清洁; Line Clearance:清场; Production Campaign:连续生产(生产周期)。
楼上有同学对于“清场”、“清洁”的含义似乎还有争议,对于大/小清场到底是不是“清洁”也有争议。可以看一下EU和USP中对于“Line Clearance”的定义,对于理解这两个定义有帮助: EU GMP Chapter 4:"Checks that the equipment and work station are clear of previous produts, documnts or materials not required for the planned process, and the equipment is clean and suitable for use. "
USP <823>: "The segregation and cleaning of different processing and work areas to avoid cross-contamination and mix-ups between the production and/or compounding of different PET drug products."
