Identification and Traceability
[As of April, 2011]
Processes
To control materials in processes and clearly define manufacturing history, Toshiba employs the following identification control methods:
- Storage racks and containers for materials, semi-finished, finished, repaird and returned products are identified by shape, color and signage to ensure that the storage and processing status of each item is clearly understood.
- At manufacturing process inspections and final inspections, the inspection status (before inspection, inspection in progress, inspected) is marked so that it is clearly understood.
- The process history of lots located amidst manufacturing processes is clearly defined using travel sheets and check sheets.
Products
Product identification is controlled by marking production lot codes to products so that the manufacturing history of any product can be traced. The following shows the typical Toshiba production lot code assignment method. If the production lot code is not possible to mark due to restrictions for package size, that is printed in the internal carton box label.
