During  planning of inspection  consideration should  also  be given  to the flow  of product through the inspection station. The inspection  station or  station should be so  planned  that they  are in  the  normal route  of the  product so that  additional movement and handling  of the  product is avoided. In  case the inspection does  not involve elaborate test equipment, mobile  inspection stations may  be organized so that these  can be  installed where  required. As far  as  possible the inspector should move  to the product rather than vice versa. In  addition  to inspection  stations where the product may be inspected visually or with the help of simple instruments there is often  a need  to have  separate  test laboratory where exhaustive tests  can be carried  out.
