| 1 | While reviewing the standard the committee felt to revise this standard keeping in view the latest developments in the tin production and refining process and also to modify the grades in the standard which have international acceptance and traded on various commodity exchanges. In the present revision, the scope of the standard has been modified to cover the refined zinc produced from either primary or secondary source/raw materials or a combination of both, in line with the international practices. The requirements of primary zinc and refined secondary zinc were previously covered in separate standards IS 209 and IS 4699 respectively. Also, the prime western grade of Zinc Zn98.65 which was earlier mentioned in IS 13229 has been included in this standards. Hence, the current revision of IS 209 supersedes the IS 4699 and IS 13229 | |
| 2 | Title of the standard has been modified from primary zinc to refined zinc inline with international practices; Scope has been enlarged and modified to cover refined zinc(both primary and secondary refined zinc) in form of ingots irrespective of the source/raw materials used ; Clause 3 on terminology has been added; Clause 4 on grades and designation has been added to include more grade of zinc ingots; Clause 5 on supply of material has been modified to include basis for order/enquiry; Clause 6 on manufacture has been modified to cover the manufacturing of zinc ingots from liquid refined zinc; Clause 7 on Chemical composition has been modified to include more grades of zinc in the standard and align the grades with internationally accepted and traded specifications; Grade 99.5 known as intermediate grade has been added; Grade 98.65 known as prime western grade used for general galvanizing purposes has been included in IS 209 which was separately covered in IS 13229 ; | |
| 3 | Shape and mass of ingots, Clause 8 has been added to include the supply of zinc in different forms other than ingot; Clause 10 on sampling has been modified to refer different method of preparing samples for chemical analysis in accordance with ISO 10081; and Annex A has been added to compare the equivalent or related chemical compositiongrades of zinc existing in various international standards and the Indian Standard. | |
