IS 17148 : Part 1 : 2024/ISO 12039 : 2019 Performance Characteristics of Automated Measurement Systems - Part 1 Carbon Monoxide, Carbon Dioxide and Oxygen from Stationary Sources

ICS 13.040.50

CHD 35

NATIONAL FOREWORD

This Indian Standard (Part 1) (First Revision) which is identical to ISO 12039 : 2019 Stationary source emissions - Determination of the mass concentration of carbon monoxide, carbon dioxide and oxygen in flue gas - Performance characteristics of automated measuring systems issued by the International Organization for Standardization (ISO), was adopted by the Bureau of Indian Standards on the recommendation of the Air Quality Sectional Committee and approval of the Chemical Division Council.

Deterioration in air quality due to pollution is a pertinent global problem. Monitoring industrial emissions so as to minimize its environmental and health effects is a major concern in a developing economy like India. Automated measurement systems (AMS) help in continuous monitoring of emissions. For accurate and effective functioning, these measurement systems shall fulfill certain performance criteria. This standard has been developed to ensure production and availability of good quality AMS instruments in India. This standard forms a part of a series of standards on performance characteristics of AMS and it is applicable for the AMS utilized for determination of carbon monoxide, carbon dioxide and oxygen from stationary source emissions.

This standard was first published in 2019 as an identical adoption of ISO 12039 : 2001 under dual numbering. This Part of standard specifies the fundamental structure and the most important performance characteristics of automated measuring systems for carbon monoxide (CO), carbon dioxide (CO2) and oxygen (O2) to be used on stationary source emissions. This document describes methods and equipment for the measurement of concentrations of these gases.

This Indian Standard is published in several parts. The other parts in this series are:

Part 2 Particulate matter from stationary sources

Part 3 Sulfur dioxide from stationary sources

Part 4 Nitrogen oxides from stationary sources

Part 5 Determination of the mass concentration of ammonia in flue gas from stationary sources

This first revision of the standard has been brought out to adopt the latest version of ISO 12039 : 2019.

In this revision, following modifications have been done:

a) The structure and the components are changed to be similar to the latest ISO standards; ISO 17179 (measurement of NH3), ISO 13199 (measurement of total VOC), ISO 25140 (measurement of CH4), ISO 21258 (measurement of N2O) and others;

b) Addition or deletion and change in terms and definitions;

c) Addition of a new analytical technique (tune able laser spectroscopy) for in-situ measurement of CO, CO2 and O2;

d) The performance characteristics and criteria as well as QA/QC procedures are changed to harmonize with latest ISO standards; and

e) Examples of performance test results and the results of uncertainty calculation are shown for CO, CO2 and O2 measurement.

The text of ISO standard has been approved as suitable for publication as an Indian Standard without deviations. Certain conventions and terminologies are, however, not identical to those used in Indian Standards. Attention is particularly drawn to the following:

a) Wherever the words 'International Standard’ appear referring to this standard, they should be read as 'Indian Standard’; and

b) Comma (,) has been used as a decimal marker in the International Standard, while in Indian Standards, the current practice is to use a point (.) as the decimal marker.
