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.
The quality grade of NEC 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
