While NEC Electronics endeavors to enhance the quality, reliability and safety of NEC Electronics 

products, customers agree and acknowledge that the possibility of defects thereof cannot be 
eliminated entirely. To minimize risks of damage to property or injury (including death) to persons 
arising from defects in NEC Electronics products, customers must incorporate sufficient safety 
measures in their design, such as redundancy, fire-containment and anti-failure features.

z

NEC Electronics products are classified into the following three quality grades: "Standard", " Special“

and "Specific". 
The "Specific" quality grade applies only to NEC Electronics products developed based on a 
customer-designated "quality assurance program" for a specific application. The recommended 
applications of an NEC Electronics product depend on its quality grade, as indicated below.
Customers must check the quality grade of each NEC Electronics product before using it in a 
particular application.

“Standard”: Computers, office equipment, communications equipment, test and measurement 

equipment, audio and visual equipment, home electronic appliances, machine tools, 
personal electronic equipment and industrial robots.

“Special”:  Transportation equipment (automobiles, trains, ships, etc.), traffic control systems, 

anti-disaster systems, anti-crime systems, safety equipment and medical equipment (not 
specifically designed for life support).

“Specific”:  Aircraft, aerospace equipment, submersible repeaters, nuclear reactor control systems, 

life support systems and medical equipment for life support, etc.

z

The quality grade of N EC Electronics products is "Standard" unless otherwise expressly specified in 

NEC Electronics data sheets or data books, etc. If customers wish to use NEC Electronics products in 
applications not intended by NEC Electronics, they must contact an NEC Electronics sales 
representative in advance to determine NEC Electronics' willingness to support a given application.

(Note)

(1)”NEC Electronics” as used in this statement means NEC Electronics Corporation and also includes 

its majority-owned subsidiaries.

(2)"N EC Electronics products" means any product developed or manufactured by or for NEC  

Electronics (as defined above).
