IS 9967 : Part 3 : 2008 /ISO 14673-3 : 2004 Milk and Milk Products - Determination of Nitrate and Nitrate Contents - Part 3 : Method Using Cadmium Reduction and Flow Injection Analysis with In-Line Dialysis (Routine Method)

National Foreword

This Indian Standard (Part 3) (Second Revision) which is identical with ISO 14673-3 : 2004 ?Milk andmilk products - Determination of nitrate and nitrite contents - Part 3: Method using cadmium reductionand flow injection analysis with in-line dialysis (Routine method)? issued by the International Organizationfor Standardization (ISO) was adopted by the Bureau of Indian Standards on the recommendation of theDairy Products and Equipment Sectional Committee? and approval of the Food and Agriculture DivisionCouncil.

This standard was first published in 1981 based on the earlier version of International Standard,ISO 4099 : 1978 and subsequently revised in 1997 to align with the revised ISO 4099 : 1984 under dualnumbering and its scope covered determination of nitrate and nitrite contents in cheese usingcadmium reduction and spectrometry. Subsequently ISO 4099 was withdrawn and revised into threeparts of ISO 14673 to include in its scope a variety of milk and milk products and also including twomore methods for determination of nitrate and nitrite contents.

Subsequently to align with ISO 14673 on the subject, IS 9967 is now being revised into three parts.Other parts are as follows:

Part 1 Method using cadmium reduction and spectrometry

Part 2 Method using segmented flow analysis (routine method)

The text of ISO Standard has been approved as suitable for publication as an Indian Standardwithout 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 shouldbe read as ?Indian Standard?.

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