NATIONAL FOREWORD

This Indian Standard (Part 5) which is identical with ISO 29042-5 : 2010 ‘Safety of machinery — Evaluation of the emission of airborne hazardous substances — Part 5: Test bench method for the measurement of the separation efficiency by mass of air cleaning systems with unducted outlet’ issued by the International Organization for Standardization (ISO) was adopted by the Bureau of Indian Standards on recommendation(s) of the Manufacturing Machinery, and Their Safety Sectional Committee and approval of the Mechanical Engineering Division Council.

This standard is published in various parts. Other parts in this series are:

Part 1 Selection of test methods

Part 2 Tracer gas method for the measurement of the emission rate of a given pollutant

Part 3 Test bench method for the measurement of the emission rate of a given pollutant

Part 4 Tracer method for the measurement of the capture efficiency of an exhaust system

Part 6 Test bench method for the measurement of the separation efficiency by mass of air cleaning systems with ducted outlet

Part 7 Test bench method for the measurement of the pollutant concentration parameter

Part 8 Room method for the measurement of the pollutant concentration parameter

Part 9 Decontamination index

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