The period of limitation for material defect claims shall apply irrespective of the operational period of use. Defects in the delivered goods shall be reported by the Customer as soon as they are detected in the ordinary course of business. If the defects are openly recognizable in the course of business of EIS, the notification shall be made within a period of one week. If the defects are not obviously recognizable, the complaint shall be made within a period of 14 days after recognition of the defects.
