Questionsand Answers on the Topic "Visual Inspection"
关于“目视检查”的问答
 
Onthe topic of visual inspection of parenterals there are always questions on howto implement in practice. The following Q&As are supposed to support you inthis implementation.
关于静脉注射液的目视检查问题，总是有一些关于在实践中如何实施的问题。以下问题可以在实施中帮助到你。
 
Question1: How often have employees of the manual (or semi-automatic) inspection haveto be trained? What does "regularly" mean in this context?
问1：进行人工（或半自动）检查的员工要多久培训一次？在这里“定时”是指多少时间？

With regard to visual inspection, the difference between initial qualificationand requalification must basically be made. Strictly speaking, requalificationis an examination of the stand of a person's qualification. It is recommendedto re-qualify employees every 3 to 6 months.
谈到目视检查，上岗培训和再培训要从根本上区分开来。严格地说，再培训是对一个员工的操作资格的一种检查，建议3-6个月进行一次。
 
Question2: The grey portion of fully automatic control is often checked manually, toreturn not clearly or fully tested products back to the inspection process. Isit allowed to carry out this testing with the automated inspection machine?
问2：全自动控制的灰色部分通常是人工检查的，它将不澄清的或全部已检测的产品返回到检查过程中去。是否允许采用自动检查设备来进行该项检查？

From a GMP view,there are no restrictions. It is also important here that at the end a yieldcalculation and evaluation in the batch record appears. And there are alsoautomated inspection systems that have already integrated the double inspectionwith multiple cameras.
从GMP角度来说，是没有限制的。这里很重要的一点是在批记录中最终的收率计算和评估。也有一些自动检查系统已经被整合成多相机双重检查设备。

Question 3: Is AQL testing mandatory as a part of the visual inspection?
问3：AQL测试是否是目视检查必不可少的一部分？

A direct requirement cannot be derived from the EU GMP. Yet, the AQL testscorrespond to the state of the art in science and technology. Since we knowthat neither man nor machine can prevent particles in the containers for beingoverlooked up to 100%, an additional measure - like the AQL tests - iscertainly appropriate. Another method would be of course a second 100% control.Or you could show in the validation that the test method 100% succeeds, whatwill hardly be possible in practice.
EUGMP中并没有这样的直接要求，但是，AQL测试对应的是理想的科学技术。由于我们都知道人工和机器均无法100%地保证检出容器中颗粒物，因此采用额外的措施（例如AQL测试）肯定是适当的。另一个方法是采用第2个100%控制，或者你可以在验证中证明检测方法会100%的成功，但这在实践中几乎是不可能的。

Question 4: Are there legal acceptance criteria or provisions regarding thesize of (visible) particles? 
问4：关于颗粒的大小（目视）是否有法规可接受标准或条款规定呢？

According to studies by Jules Knapp, people can recognise particles underoptimal conditions from 30 - 50 μm, taking into account the colour of theparticle. Other studies have shown that eventually particles from approximately200 μm can be surely detected - in other sources, values of 50-80 μm can befound. There are (still) no statutory limits on the size of the visibleparticles.
根据JULESKNAPP的研究，人们肉眼在较好视线条件下，同时考虑微粒颜色情况下，可以发现30-50μm的微粒。其它研究表明约200μm的微粒肯定是可以被检查到的，在其它来源中，50-80μm的微粒是可以被发现的。暂无可见微粒大小的法定限度。

Question 5: Can one 'reject' test be considered as a good after two"good" inspection on the same machine?
问5：一份被“拒收”的样品在同一台机器上经过2次“结果良好”的检查后是否可以认为是一个好的样品？

This is possible in a few cases where - for example - the machine stopped andgoods were therefore ejected. Otherwise, "reject" should alwaysremain "reject". This is particularly applicable to "bad"goods which have been rejected because of particles or opacity. Containerssorted out due to cosmetic defects are however usually being re-inspected.
这时可能出现不同情况-----例如----设备停止，产品因此被拒。否则，“被拒”只能维持作为“被拒”状态，这种情况特别适用于“坏”产品因为微粒或透明度的问题被拒时。由于容器外观缺陷而被拒的样品一般是可以进行再次检查的。

Question 6: Are there empirical values about how long do lamps insemi-automatic testing stations keep their intensity?
问6：半自动检查站的灯可以在多长时间内保持其强度是否有经验值？

Here, the certificates of the lamp manufacturers should be consulted. As arule, 2-3 years are indicated. Frequently, the lamps will be exchangedroutinely after one year to never have to question the test results due topossible lamp weakness retroactively.
这里，可以参考灯的生产商的证书。一般来说会指明是2-3年。更多时候，每1年常规地把灯换掉，这样就永远不会因为灯的照度不够而被质疑
