GB/T 13971-2013Specification of ultraviolet gas analyzers (English PDF)

Foreword

This standard was drafted in accordance with GB/T 1.1-2009 given rules. The revised standard and replaces GB/T 13971-1992 "UV gas analyzer technical conditions." The standard on the technical content of the original standard main changes are as follows:

--- Revised linearity error, repeatability, output fluctuations, zero drift, span drift performance requirements;

--- Increasing the requirements and test methods affect the amount of supply voltage;

--- Increasing the requirements and test methods affect the amount of interference gas component;

--- Increased requirements and test methods for mechanical vibration amount;

--- Remove the impact of changes in atmospheric pressure - Requirements and test methods. The standard proposed by China Machinery Industry Federation. This standard by the national industrial process measurement and control Standardization Technical Committee (SAC/TC124) centralized. This standard by the FPI (Hangzhou) Co., Ltd. is responsible for drafting, Sichuan-Chongqing Analytical Instruments Co., Ltd., Wuhan Tianhong Instrument Co., Ltd., Shanghai Institute of Metrology, Hangzhou Environmental Monitoring Center, and other units to participate in the drafting. The main drafters of this standard. Michael, Ye Huajun, Wang Xinyuan, Li Caodong, WC Keung years, Cai Jianhua, He Xi. This standard replaced the previously issued standards.

1 Scope

GB/T 13971-2013 is the Chinese national standard on specification of ultraviolet gas analyzers, in the field of chemical technology. The /T suffix marks it as a recommended standard: it is not compulsory by itself, but it becomes binding as soon as a contract, a tender or a customer specification calls it up - which in practice is how most foreign buyers meet it. It was issued on 17 December 2013 by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China; Standardization Administration of China, and has been in force since 1 June 2014. Classification: ICS 71.040, CCS N53. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This standard specifies the requirements, test methods, inspection rules ultraviolet gas analyzer, signs, packaging, transportation and storage. This standard applies to the determination of a component of the mixed gas concentration, regardless of ultraviolet light gas analyzer (hereinafter referred to as equipment), not including UV spectral absorption spectroscopy and UV fluorescence spectroscopy gas analyzer gas analyzer, ultraviolet wavelength range of 150nm ~ 400nm.
