BS EN ISO 6145-7:2018是一系列文件，涉及用于制备校准气体混合物的各种动态方法。本文件规定了使用热质量流量控制器从名义纯气体或气体混合物中连续制备校准气体混合物的方法。该方法适用于制备非反应性物质的混合物，即不与热质量流量控制器或辅助设备中的流道结构的任何材料反应的混合物。交叉引用: ISO 6145-1ISO 7504ISO 19229ISO 6143ISO 12963GUM:1995ISO 6142-1ISO/IEC指南98-3:2008ISO 14511:2001购买本文件时可获得的所有现行修订版均包含在购买本文件中。

BS EN ISO 6145-7:2018 is a series of documents dealing with various dynamic methods used for the preparation of calibration gas mixtures. This document specifies a method for continuous preparation of calibration gas mixtures, from nominally pure gases or gas mixtures by use of thermal mass-flow controllers. The method is applicable to preparation of mixtures of non-reacting species, i.e. those which do not react with any material of construction of the flow path in the thermal mass-flow controller or the ancillary equipment.Cross References:ISO 6145-1ISO 7504ISO 19229ISO 6143ISO 12963GUM:1995ISO 6142-1ISO/IEC Guide 98-3:2008ISO 14511:2001All current amendments available at time of purchase are included with the purchase of this document.
