Ambient atmospheres — Sampling of wet deposition
Guide to Reference and Standard Atmosphere Models
Recommendation ITU-R P.676 provides methods to estimate the attenuation of atmospheric gases on terrestrial and slant paths using
Attenuation by Atmospheric Gases
Standard a tmosphere
Specifies the characteristics of the Atmosphere Type ISO which is applicable to planning under identical conditions, to test results end elements

本规程适用于大气采样器的首次检定、后续检定和使用中检查
Air Samplers
本标准规定了模拟大气尘的原料、成分配比以及包装贮存和使用条件。 模拟大气尘适用于模拟受到工业污染的城市大气尘对空气过滤器进行性能试验;对大气含尘浓度进行模拟,在配合其他环保设备的性能测试时可参考采用
