本文档简要概述了详细描述的每种动态技术 在ISO 6145的后续部分中。本文件提供基本信息，以支持知情的 选择一种或另一种制备校准气体混合物的方法。它还描述了如何 这些方法可以与国家测量标准联系起来，以建立计量溯源性 用于制备的气体混合物的组成。 由于所有技术都是动态的，并且依赖于流速，因此本文件描述了校准过程 通过测量装置产生的每个单独流量。交叉引用:ISO 6143ISO 12963ISO 14912ISO 7504ISO 19229ISO 16664:2017ISO 6142-1ISO 5725-1ISO 11114-2ISO 11114-1购买本文件时可用的所有当前修订版均包含在购买本文件中。

This document gives a brief overview of each of the dynamic techniques which are described in detail in the subsequent parts of ISO 6145. This document provides basic information to support an informed choice for one or another method for the preparation of calibration gas mixtures. It also describes how these methods can be linked to national measurement standards to establish metrological traceability for the composition of the prepared gas mixtures. Since all techniques are dynamic and rely on flow rates, this document describes the calibration process by measurement of each individual flow rate generated by the device.Cross References:ISO 6143ISO 12963ISO 14912ISO 7504ISO 19229ISO 16664:2017ISO 6142-1ISO 5725-1ISO 11114-2ISO 11114-1All current amendments available at time of purchase are included with the purchase of this document.
