IS 7190 : Part 1 : 2024/ISO 567 : 2021 Coke - Methods of Test - Part 1 Determination of Bulk Density in a Small Container
NATIONAL FOREWARD
This Indian Standard (Part 1) (Second Revision) which is identical to ISO 567 : 2021 'Coke - Determination of bulk density in a small container' issued by the International Organization for Standardization (ISO) was adopted by the Bureau of Indian Standards on the recommendations of the Solid Mineral Fuels and Solid Biofuels Sectional Committee and approval of the Petroleum, Coals and Related Products Division Council.
This Indian Standard was originally published in 1974 and subsequently revised in 2004. The 1974 version covered the methods for determination of bulk density of coke in a small container (based on ISO/R 567 : 1967) and determination of bulk density of coke in a large container (based on ISO/R 1013 : 1969). As ISO/R 567 : 1967 and ISO/R 1013 : 1969 were adopted as ISO 567 : 1974 and ISO 1013 : 1975 respectively, the committee decided to adopt these two standards under dual numbering in the year 1995. Consequently, the first revision was taken place to bifurcate the standard into two parts with modified title as:
IS 7190 (Part 1) : 2004 /ISO 567 : 1995 Coke - Methods of test: Part 1 Determination of bulk density in a small container (first revision)
IS 7190 (Part 2) : 2004/ISO 1013 : 1995 Coke - Methods of test: Part 2 Determination of bulk density in a large container (first revision)
This revision is undertaken to align it with the latest version of ISO 567 : 2021. The major changes in this revision are as follows:
a) Referenced documents have been updated;
b) Term and definitions have been modified;
c) Minimum capacity of mass determination scale/machine has been modified;
d) Test sample clause has also been modified; and
e) The container to be used for determination of coke bulk density can either be cubical or cylindrical in shape with a capacity 0.2 m3.
The other part in this series is:
Part 2 Determination of bulk density in a large container
The text of ISO standard has been proposed to be 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.
