What are the color grades of military imported electronic components? What do they mean? Thank you, thank you, thank you! ! !

The color grades of military imported electronic components may be different according to different standards. The following are two possible standards and their corresponding color grades and meanings:

1. According to GJB standard, the safety color grades of components are divided into five grades, namely, red, yellow, blue, white and green. Among them, red represents the highest security level and green represents the lowest security level. Specifically, red rated components are usually used in demanding military equipment and high-end industrial products, such as missiles and aircraft. Yellow-class components are suitable for civilian equipment with high safety requirements, such as medical equipment and nuclear power plants. Blue-class components are suitable for civilian equipment with general safety requirements, such as televisions and computers. White-class components are suitable for products with low safety requirements, such as household appliances; Green components are usually only suitable for some low-end products, such as toys.

2. According to another possible classification standard, the color grades of electronic components are divided into four grades: red, orange, yellow and blue. Where blue is the lowest level and red is the highest level. Different levels correspond to different safety requirements and use environments, with specific meanings as follows:

-Blue level: the lowest safety level, generally used for low-frequency circuits and low-risk equipment.

-Yellow grade: slightly higher than blue grade, generally used for civil equipment and industrial equipment.

-orange grade: higher than yellow grade, generally used for military products and aerospace equipment.

-Red level: the highest security level, generally used for the most sensitive military equipment and key systems.

It should be noted that different standards may have different color grades and corresponding meanings, depending on the standard.
