IS 5402 : Part 2 : 2021/ISO 4833-2 : 2013 Microbiology of the Food Chain - Horizontal Method for the Enumeration of Microorganisms - Part 2 Colony Count at 30°C by the Surface Plating Technique

New Standard from Last Update.

NATIONAL FOREWORD

This Indian Standard (Part 2) which is identical to ISO 4833-2 : 2013 ‘Microbiology of the food chain — Horizontal method for the enumeration of microorganisms — Part 2: Colony count at 30°C by the surface plating technique’ issued by International Organization for Standardization (ISO) was adopted by the Bureau of Indian Standards on recommendation of the Food Hygiene, Safety Management and Other Systems Sectional Committee and approval of the Food and Agriculture Division Council.

This standard was originally published in 1969 and subsequently revised in 2002 and 2012. First revision of this standard was identical with ISO 4833 : 1991. The second revision of the standard was an identical adoption of ISO 4833 : 2003 under dual numbering.

Subsequently, ISO 4833 was revised in 2013 into two parts under the general title ‘Microbiology of the food chain — Horizontal method for the enumeration of microorganisms’:

Part 1 Colony count at 30°C by the pour plate technique

Part 2 Colony count at 30°C by the surface plating technique

Accordingly, in this third revision of IS 5402, the standard has been split into two parts, Part 1 is an identical adoption of ISO 4833-1 : 2013 and Part 2 is an identical adoption of ISO 4833-2 : 2013.

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.
