In the “Nissan H7300 NADS0 Kit-Seat Cover” standard developed by Nissan automobile company, the features of car seat covers for dealer option are described.

The seat cover will have one or more of the following functions:

Nissan Automobiles has established general reliability targets for parts or systems according to the table in the standard. However, the failure degrees in the table are based on the company's understanding of the expected possible failure modes of the parts or systems. The supplier determines the possible failure modes of the parts or systems known to it and reports them to Nissan. The supplier is responsible for fulfilling all requirements (including additional failure modes) described in this table.

The table contains the description of the faults, typical fault examples, their useful life and the reliability target to be guaranteed.
