NATIONAL FOREWORD

This Indian Standard (Part 2) which is an identical adoption of ISO 10155 : 1995 ‘Stationary source emissions - Automated monitoring of mass concentration of particles - Performance characteristics, test methods and specification’ issued by the International Organization for Standardization (ISO) was adopted by the Bureau of Indian Standards on 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 particulate matter from stationary source emissions.

The text of ISO Standard has been approved as suitable for publication as an Indian Standard without deviations. Certain terminologies and conventions 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’.

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