Methods of Sampling and Test for Paper and Allied Products - Part 8 Methods of Test for Paper, Board, Pulps and Cellulose Nanomaterials - Section 3 Determination of Acid-Soluble Magnesium, Calcium, Manganese, Iron, Copper, Sodium and Potassium

This Indian Standard (Part 8/Sec 3) which is identical to ISO 12830 : 2019 'Paper, board, pulps and cellulose nanomaterials - Determination of acid-soluble magnesium, calcium, manganese, iron, copper, sodium and potassium' 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.

Presence of different elements such as calcium, manganese, iron, copper, sodium, etc. affects the quality and performance characteristics of the paper, pulp and boards. It is therefore essential to standardize the methods of quantification of such elements in paper, board, pulp and cellulosic nanomaterials.

ISO has published test method standards related to paper, pulp and board under three broad categories namely 'Paper, board and pulps', 'Paper and board' and 'Pulps'. Related Indian Standards published in IS 1060 (Parts 1, 2 and 3) 'Methods of sampling and test for paper and allied products' and IS 6213 series of standards published for 'Methods of test for pulps' are widely recognized and used in India. To maintain consistency with the prevailing international practices and to retain the existing test methods series, the committee responsible for formulating this standard decided to harmonize the methods of tests prescribed in IS 1060 series and IS 6213 series with those published by ISO and publish these adopted test methods standards in subsequent parts/sections of IS 1060 series or IS 6213 series.
