GB/T 10593.2-2023 "Methods of Measuring Environmental Parameters for Electrical and Electronic Products - Part 2: Salt Mist" is applicable to the measurement of salt mist environmental parameters in the usage locations of electrical and electronic products. It specifies the sampling, analysis, and calculation methods for salt mist concentration, deposition rate, and deposition amount. The determination of salt mist concentration is carried out using the aspiration method, paired with specific reagents and sampling devices, with requirements such as an absorption efficiency of ≥90% and a detection limit of 0.05 mg/m³ clearly defined. The deposition rate can be measured using the wet candle method or the dry plate method, and includes specifications for online monitoring technology. During sampling, data such as temperature, humidity, and air pressure must be recorded to provide data support for the environmental adaptability assessment of related products.
