IS 11963 : 2005 /ISO 5548 : 2004 Caseins and Caseinates - Determination of Lactose Content - Photometric Method

National Foreword

This Indian Standard (First Revision) which is identical with ISO 5548 : 2004 !Caseins and caseinates - Determination of lactose content - Photometric method? issued by the International Organization for Standardization (ISO) was adopted by the Bureau of Indian Standards on the recommendations of the Dairy Products and Equipment Sectional Committee and approval of the Food and Agriculture Division Council.

This standard was first published in 1987 based on the earlier version of the International Standard, namely, ISO 5548 : 1980 under dual numbering. This standard is being brought out to align it with the latest edition of the ISO Standard.

The text of the ISO Standard has been approved as suitable for publication as an Indian Standard without deviations. Certain terminology and conventions are, however, not identical to those used in Indian Standards. Attention is particularly drawn to the following:

) 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.

In this adopted standard, reference appears to the following International Standard ?for which Indian Standard also exists. The corresponding Indian Standard which is to be substituted in its place is listed below along with its degree of equivalence for the edition indicated.
