A product specification determines which suite of tests will be carried out on a product. A product can have many specifications during the production process. For example: internally PARACETAMOL tablets may be finished from the intermediate product in several stages - Granulation, Tableting, Coating and Packaging. Each of these stages may require different specifications and testing while being identified as the same product/lot within the system. This same final product may also have many different specifications that must also be checked. Each of the tests on these specifications may have different acceptance and warning limits. Only if the result determined is within the acceptance limits can the test be approved.
