IS 1493 : Part 5 : 2020/ISO 5418-2 : 2006 Methods of Chemical Analysis of Iron Ores - Part 5 Determination of Copper Content-Flame Atomic Absorption Spectrometric Method

Revised Standard from Last Update.

NATIONAL FOREWORD

This Indian Standard (Part 5) (First Revision) which is identical with ISO 5418-2 : 2006 ‘Iron ores — Determination of copper — Part 2: Flame atomic absorption spectrometric method’ issued by the International Organization for Standardization (ISO) was adopted by the Bureau of Indian Standards on recommendation of the Methods of Chemical Analysis of Metals Sectional Committee and approval of the Metallurgical Engineering Division Council.

This standards was originally published in 1990 which was identical with ISO 4693 : 1983. Subsequently, ISO 4693 : 1983 was technically revised to ISO 5418-2 : 2006 ‘Iron ores — Determination of copper — Part 2 : Flame atomic absorption spectrometric method’. The first revision of this standard has been undertaken to align it with the latest version of ISO 5418-2 : 2006.

The Standard has been published in 10 parts. The other parts of this standard are:

Part 1 Determination of common constituents

Part 2 Determination of Silicon Content by reduced Molybdosilicate spectrophotometric Method

Part 3 Determination of titanium, Chromium, Vanadium, Calcium and magnesium by atomic absorption spetrophotometry

Part 4 Determination of aluminium by atomic absorption spectrophotomety

Part 6 Determination of sodium contents — Flame atomic absorption spectrometric method (first revision) (under print)

Part 7 Methods of chemical analysis of iron ores — Part 7 Determination of Lead Content — Flame Atomic Absorption Spectrometric Method (first revision) (under print)

Part 8 Determination of arsenic content — Molybdenum blue spectrophotometric method (first revision)

Part 9 Determination of potassium — Flame atomic absorption spectrometric method (first revision) (under print)

Part 10 Determination of zinc — Flame atomic absorption spectrometric method (first revision) (under print)

The text of ISO standard has been approved as suitable for publication as an Indian Standard without deviations. Certain terminologies and conventions are, however, not identical with 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 as 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.
