Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009. This standard uses the translation method equivalent to ISO 16664.2017 "Guidelines for the use of pure gas and mixed gases for gas analysis and calibration". This standard was proposed by the China Petroleum and Chemical Industry Federation. This standard is under the jurisdiction of the National Gas Standardization Technical Committee (SAC/TC206). This standard was drafted. Southwest Chemical Research and Design Institute Co., Ltd., Dalian Date Gas Co., Ltd., Tianjin Lianbo Chemical Co., Ltd. Company, Shaanxi Environmental Monitoring Center Station, Guangdong Huate Gas Co., Ltd., Shanghai Huaai Chromatography Analysis Technology Co., Ltd. The main drafters of this standard.

Gas analysis calibration with pure gas and mixed gas user's guidance Safety Precautions---In addition to this standard, countries and international safety related to the storage, use and transportation of pure gas and mixed gas should also be followed. Full regulation.

1 Scope

This standard describes factors that may affect the composition of a pure gas or a homogeneous mixture of gases for calibration. This standard only applies to pure gas during the validity period. Or a mixture of gases. It provides guidance on the handling and use of calibration gases from the following aspects. --- Calibration gas cylinder storage; --- Extract the calibration gas from the cylinder; --- Transfer calibration gas from the cylinder to the calibration point. This standard also outlines methods for assessing the stability of calibration gases, taking into account the uncertainty of the gas composition given by the certificate and The measurement uncertainty of the household.
