NATIONAL FOREWORD
This Indian Standard which is identical with ISO 11476 : 2000 ‘Paper and board — Determination of CIE
whiteness, C/2° (indoor illumination conditions)’ issued by the International Organization for Standardization
(ISO) was adopted by the Bureau of Indian Standards on the recommendation of the Paper and Its Products
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 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.
The technical committee has reviewed the provision of the following International Standards referred in this
adopted standard and has decided that they are acceptable for use in conjunction with this standard:
International Standard Title
ISO 186 : 2002 Paper and board — Sampling to determine average quality
ISO 2469 : 2007 Paper, board and pulps — Measurement of diffuse radiance factor
ISO 2470 : 1999 Paper, board and pulps — Measurement of diffuse blue reflectance factor (ISO
brightness)
In reporting the result of a test made in accordance with this standard, if the final value, observed or
calculated is to be rounded off, it shall be done in accordance with IS 2 : 1960 ‘Rules for rounding off
numerical values (revised)’.
