NATIONAL FOREWORD

This Indian Standard (Part 1) (First Revision) which is identical with ISO 3034 : 2011 ‘Corrugated fibreboard — Determination of single sheet thickness’ 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 increasing use of corrugated fibreboard for transport containers has given an impetus to this industry for expansion. The growing demand for this product has brought to the fore the need of evaluating the various physical characteristics of the corrugated fibreboard. The standards on test methods for these characteristics are being established for proper evaluation and reproducibility of the test results under different conditions. Thickness of the corrugated fibreboard is measured for the use of the designer of the fibreboard case and can vary a great deal when non uniform pressures for different measurements are applied on the micrometer. This test method for determining the thickness of the test pieces of corrugated fibreboard, when measured under specific pressure, gives repeatable and consistent results.

This standard was first published in 1973. Considering the importance of following the uniform practices globally, the committee felt the need of revising this standard and also felt that it would be more appropriate to prepare this standard test method by adoption of ISO 3034.

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.
