Certification Bodies for Product, such as the inspection body, determines whether something has met the appropriate requirements or not. This may involve a product, service, or process. The main difference is that they not only examine a sample or a batch but they also check the company. So they went further. Their assessment also applies to the next product, service or process that is not checked by them. Whether the batch quickly meets the specified requirements or not. And can we believe that the next batch is produced in the same way or not. If the answer is positive, the manufacturer may use the relevant mark. A product certification body will continue to provide oversight to a certified company.
