TO PRODUCT MANUAL FOR Stainless Steel Sheets and Strips for Utensils According to IS 5522:2014 GROUPING GUIDELINES In order to align with existing guidelines for steel items and uniform practice is followed, the following procedure to be adopted towards grant of licence andinclusion of additional varieties. 1. Grouping as per different variety of stainless steel on the basis of chemical composition/alloying elements: Grade Designation Group 1 Austenitic 304 and 302 Group 2 Ferritic 430 2. One sample from each group of any grade designation of Stainless Steel Sheets and Strips for Utensils applied for licence/inclusion may be drawn and has to be tested for all the requirements of the specification and applicable to the variety tested. If the sample passes, then licence may be granted/inclusion be done for the Grade designation of Stainless Steel Sheets and Strips for all sizes for Utensils for the Group, provided that the firm is having all the necessary manufacturing and testing facilities for the manufacture and testing of the sizes/grades designation/varieties of Stainless Steel Sheets and Strips for Utensils to be

included in the licence. 3. Surface Finish: Certain surface finishes get converted to superior surface finishes based on further processing. Further, some surface finishes are independent of each other. Hence, surface finish type shall be restricted depending upon the manufacturing facility available with the firm. 4. Manufacturing/Testing facilities & capabilities including online to be verified with respect to sizes/grades designation/varieties and accordingly same may be covered in the scope of license. 5. While considering GOL/Inclusion of additional varieties, it shall be ensured that the applicant/ licensee has got the complete manufacturing and testing facilities for all the sizes/grades/designation/varieties applied. 6. Erichsen Cupping Test (Clause 8.5 of IS 5522 : 2014) is subject to agreement between purchaser and the manufacturer. Exclusion / Inclusion of Erichsen Cupping Test in scope of licence will be based accordingly. 7. During the operation of license, BO shall ensure that all thesizes/grades/designation/varieties covered in the license are drawn for independent testing on rotation over a period of time.
