Scope of use
This standard is applicable to military semiconductor discrete devices
Application Guidelines
It is stipulated that the test conditions in the laboratory should be appropriate, so that the test results are equivalent to the results of on-site use, and the test results should be reproducible.
. But this cannot be understood as the experimental conditions being completely equivalent to the actual working conditions in a certain region, because only the actual working experiments in a certain region are the actual working experiments in that region. When using a standard to describe test methods with similar properties in various general semiconductor device specifications, these methods can be kept unified, thereby fully utilizing equipment, facilities, and saving time. To achieve this goal, it is necessary to make each universal test method applicable to multiple devices. When referencing the test methods of this standard in detailed specifications, the standard number, test method number, and the details that should be specified in the referenced test methods should be indicatedReference
