2. The factory inspection items are subject to product inspection according to the requirements of appearance quality, adhesion, lubricity, and sterility. The inspection items include appearance quality, characteristic indicators, etc.
3. According to the normal inspection one-time sampling plan in the standard, the inspection items and acceptance quality limit AQL level inspection level are shown in the following four inspection items.
Exterior
Tightness
Lubricity
Sterile
4. In the inspection results of prefilled syringes, according to the sampling inspection procedure by attributes Part 1: Retrieved by the acceptance quality limit, the batch-by-batch inspection sampling plan determines that the sealing is unqualified, then it is judged as unqualified; if there are unqualified in other items Yes, double sampling is allowed for re-inspection of unqualified items.
