Impact analysis on sub-product performance.
---Part 2.Salt Spray. This part is mainly aimed at the measurement of salt spray parameters in electrical and electronic product environments to provide guidance for salt spray environments.
Corrosion protection of electrical and electronic products, environmental optimization control, etc.
---Part 3.Vibration data processing and induction. This part mainly provides a detailed analysis of environmental vibration parameter data processing in order to
Analyze vibration parameters to guide the control of vibration conditions in the safe service environment of electrical and electronic products.
---Part 4.Condensation. This part is mainly aimed at measuring the condensation parameters of electrical and electronic products, and can provide guidance on the safety services of electrical and electronic products.
Control humidity to reduce the possibility of short circuits, failure of electronic components and other failures caused by condensation.
This document is for the revision of Part 2 of GB/T 10593.This revision aims to improve the atmospheric salt spray monitoring method.
