IS 1060 : Part 5 : Sec 8 : 2024/ISO 2493-2 : 2020 Methods of Sampling and Test for Paper and Allied Products - Part 5 Methods of Test for Paper and Board - Section 8 Determination of Bending Resistance - Taber-Type Tester
NATIONAL FOREWORD
This Indian Standard (Part 5/Sec 8) (First Revision) which is identical to ISO 2493-2 : 2020 'Paper and board - Determination of resistance to bending - Part 2: Taber-type tester' 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.
ISO has published relevant test method standards under the three broad based titles namely 'Paper, board and pulps', 'Paper and board' and 'Pulps'. To maintain consistency with the prevailing international practices and also to facilitate search of the relevant test methods instantly, all the adopted standards are published under the following two series;
IS 1060 series on 'methods of sampling and test for paper and allied products':
Part 4 Methods of test for paper, board and pulp
Part 5 Methods of test for paper and board
Part 6 Methods of test for paper
Part 7 Methods of test for board
IS 6213 series for 'methods of test for pulps'.
This standard was originally published in 1969 as IS 1060 (Part 3). The test methods, not very commonly used and indented for special purpose, were neither covered by IS 1060 (Part 1) nor IS 1060 (Part 2), had been covered in IS 1060 (Part 3).
Considering the benefits of aligning standards with that of international best practices, in 2014, the Committee decided to revise this standard by identical adoption of ISO 2493-2 : 2011, 'Paper and board - Determination of resistance to bending - Part 2: Taber-type tester' under dual numbering and published it under IS 1060 (Part 5).
During this revision, considering that 2014 version of this standard was identical adoption of ISO 2493-2 : 2011, the Committee decided to further revise the standard by aligning it with ISO 2493-2 : 2020, under dual numbering. During this revision, following changes have been made:
a) Additional data to be reported in 12; and
b) Several editorial updates.
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'; and
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.
