New Standard from Last Update.

NATIONAL FOREWORD

This Indian Standard which is identical with ISO/TS 24520 : 2017 ‘Service activities relating to drinking water supply systems and wastewater systems — Crisis management — Good practice for technical aspects’ issued by the International Organization for Standardization (ISO) was adopted by the Bureau of Indian Standards on recommendation of the Environment Protection Sectional Committee and approval of the Chemical Division Council.

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/document’ 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.
