发布日期： 2018-12-21

BS EN ISO 21083-1:2018规定了测定部分过滤的测试仪器和程序
平板过滤介质对20 nm至500 nm范围内空气中纳米颗粒的效率。
本文件中的测试方法仅限于球形或接近球形的颗粒，以避免
由于颗粒形状的不确定性。交叉引用:ISO 29463-1ISO 5725-2ISO 5167ISO 15900ISO 27891ISO 29464ISO 35ISO/TS 21083-2ISO/TS 80004-2ISO 16890-2ISO 5725-1ISO 16890-1ISO 29463-2ISO 29463-3ISO 29461-1ISO/TS 19713-1:2010购买本文件时可提供的所有当前修改件均包含在购买本文件中。

BS EN ISO 21083-1:2018 specifies the testing instruments and procedure for determining the fractional filtration
efficiencies of flat sheet filter medium against airborne nanoparticles in the range of 20 nm to 500 nm.
The testing methods in this document are limited to spherical or nearly-spherical particles to avoid
uncertainties due to the particle shape.Cross References:ISO 29463-1ISO 5725-2ISO 5167ISO 15900ISO 27891ISO 29464ISO 35ISO/TS 21083-2ISO/TS 80004-2ISO 16890-2ISO 5725-1ISO 16890-1ISO 29463-2ISO 29463-3ISO 29461-1ISO/TS 19713-1:2010All current amendments available at time of purchase are included with the purchase of this document.
