If it is determined that a review is needed of the quality or technology of the material that your company wishes to supply, such testing will be conducted.

III.After-Sale Care and Quality Assurance

In our railway business to which top priority is given to maintaining safe and reliable operation and which requires us to continue to stably and satisfactorily fulfill that social mission over the long-term, the maintenance of long-term quality is also required of the materials used, so a quality assurance system is agreed to contractually on an individual basis in transactions for materials.
Accordingly, it is very important that suppliers guarantee the quality of their materials after delivery as in "II. Material Transaction Procedures" and that they provide after-sales care, including maintenance and repairs.
In addition, in the event an abnormality arises in connection with a material, JR Central needs the supplier to respond rapidly including providing support information on technical aspects, conducting inspections, determining the cause of an abnormality, and cooperating with JR Central's investigation.
A description of the specific after-sales care and quality assurance required by JR Central is given in the "What is Required of Our Suppliers".
