2. It is certainly possible to take the method of consulting company to collect evidence, but if you plan to develop the laboratory for a long time, it is still recommended to take formal channels and learn from yourself. The consulting company will help you collect evidence, even help you pass cnas audit, and you will have to do it yourself in the future. Inspection and testing is a serious job, not iso 9000. The consulting company will help you get the certificate and hang it on the wall. The supervision of the laboratory will become more and more strict, and if you don't understand it, you won't be able to pass the audit in the future.

The requirements of the two are the same, but they also have their own requirements. It is recommended to learn from them, and there is no specific requirement for the number. In fact, the on-site evaluation of experts mainly depends on whether the personnel have the ability and the certificate is not the focus of attention. It's no use having a certificate and unclear system management in the laboratory.
