The inspection above shall be performed on each model. Here, when the first 3 digits of the
registered model are the same, they are treated as the same model in principle. However, for
each inspection item, when the engineering specification that generates the target quality
characteristic for the item is different, they shall be treated as separate models. Also, when
the engineering specification that generates the target quality characteristic for each
inspection item is the same, they can be treated as the same model.
