PM/ 1875/ 3Sep 2021ANNEXURE ATO PRODUCT MANUAL FORCARBON STEEL BILLETS, BLOOMS, SLABS AND BARS FOR FORGINGSAccording to IS 1875:1992GROUPING GUIDELINESPage 1 of 1In order to follow a uniform policy in the drawl of samples for independent testing for thepurpose of grant of license/ inclusion of additional varieties in the existing license, the procedureas mentioned below is to be followed:1. One sample of Carbon Steel Billets, Blooms, Slabs and Bars for forgings as given below forClass & Designation (also see Table 1& Table 2) has to be tested for all the requirements ofthe specification and applicable to the variety tested. If the sample passes, then licence maybe granted/inclusion may be done for Class & Designation as per the groupings given below,provided that the firm is having all the necessary manufacturing and testing facilities for themanufacture and testing of the Class of Carbon Steel Billets, Blooms, Slabs and Bars forforgings to be included in the licence.ClassDesignationNo of sample114C6One sample of any size of any Class&1A15C8Designation may be drawn. If sample is tested forhigher Class & Designation the recommendation220C82A25C8may include lower Class & Designation330C83A33 C8For example, if a sample of class 6 & designation 65C6 is445C8drawn for testing and found passing then grant of licencemay be considered for the classes 1,1A,2,2A,3,3A,4, 5 & 6,555C8subject to provision that the firm is having necessary665C6manufacturing and testing facilities for the class of carbonsteel billets, bloom, slabs & bars for forgings to be includedin the scope of the licence.2. The sample tested may be any of the size (see Cl.8) from Carbon Steel Billets, Blooms, Slabsand Bars for forgings specified in the specification. However, the licence can be granted forall the sizes of the Carbon Steel Billets, Blooms, Slabs and Bars for forgings specified in thespecification and applied by the applicant/licence, provided that the firm is having all thenecessary manufacturing and testing facilities for the manufacture and testing of all othersizesof the Carbon Steel Billets, Blooms, Slabs and Bars for forgings proposed to be includedin the licence.3. In case the manufacturer is desirous of supplying the product along with supplementaryrequirements, an undertaking to this effect is to be obtained from applicant/licensee.4. During the operation of licence, BO shall ensure that all the sizes of the Carbon Steel Billets,Blooms, Slabs and Bars for forgings covered in the license are drawn for independent testingon rotation over a period of time.5. In case of licensees supplying products along with purchaser‟s supplementary requirements,BO shall ensure that samples drawn as mentioned at 4) above be tested for supplementarytests as well, provided that samples from same Heat/Batch of Carbon Steel Billets/ Blooms/Slabs/ Bars for forgings supplied to the purchaser with agreed upon supplementaryrequirements are available during surveillance.
