specification on CMD/PF 306.
(b) Acceptance of revised STI.
(c) Test report indicating conformity of the product to the revised specification (Inhouse factory test report/independent test report)
(ii)
An early inspection shall be planned to verify the availability of testing equipment as
per revised standard with the licensees after obtaining declaration on CMD/PF 306.
During the inspection sample shall be drawn for independent testing to ensure
conformity of the product to the revised standard.
(iii)
Action shall be taken as per OMPC 2004, if the licensee fails to submit the
acceptance of STI in stipulated time. Likewise, in case sample drawn during
inspection fails in factory/independent testing as per the revised version, further
actions are to be taken as per OMPC 2004.
For Applicants:
7.
(i)
All new applications may be recorded and processed as per revised IS 3024 :2015
(ii)
In case applicant sample is already tested, the GOL shall be processed as per as
per the old/revised version of the Specification as requested by the firm. However,
in case the GOL has been processed as per the old version of the Specification, an
undertaking shall be obtained from the firm that the actions required as per revised
IS 3024 :2015 shall be completed before 21 04 2016.
(iii)
In case applicant sample is yet to be tested by Lab, necessary action may be taken
immediately by BO for considering the case as per IS 3024 :2015 after consulting
the applicant.
Revised STI DOC: STI /3024 /2, December 2015 will be implemented and will run
concurrently with the earlier version of the STI till 21 04 2016 after which the

of
such
checks/
calibration shall be maintained.
2. Test Records - All records of tests and analysis shall be kept in suitable forms approved by the
Bureau.
Note: The existing forms etc. as being maintained by the manufacturers may be retained. These
forms, however, shall contain all the information required for operating this scheme of Testing and
Inspection.
2.1 Copies of any records or charts that may be required by the BIS shall be made available at any
time on request.
3 Quality Control – It is recommended that, as far as possible. Statistical Quality Control (SQC)
methods may be used for controlling the quality of the product during production as envisaged in this
scheme (See IS 397 (Part 1) :2003 to IS 397 (Part IV): 2003) to control the quality during production.
3.1 In addition efforts should be made to gradually introduce the Quality Management System in
accordance with IS/ISO 9001.
4 Standard Mark – The Standard mark as given in column (1) of the first schedule of the licence is
specified for grain oriented electrical steel sheet and strip specified in IS 3024:2015. The grade
designation shall be mentioned in the Test Certificate.
4.1 Test Certificate – For each consignment of BIS Certified material conforming to IS:3024:2015
there shall be a test certificate which shall contain the standard Mark, the Coil / pallet no. cast/batch
number, grade designation, nominal thickness & size, delivery condition and the corresponding test
results ( as given in Annexure I)
4.2 Marking – Each bundle of sheets/ strip shall be marked legibly and indelibly as follows:
a) Test Number or Lot Identification No.,
b) Date of Manufacture (Year, Month ),
c) Manufacturer’s name or trade mark, if any;
d) Grade,

4.3 Designation of Grades – Grain Oriented electrical steel sheets / strips shall be designated as
given in clause 6 of the specification.
4.4 Packing – Unless otherwise stated the sheets / strips shall be suitably packed in metal protected
container lined with water – proof material lining to avoid any damage and to ensure protection from

production which conforms to the Indian Standard and covered by the licence shall be marked with
certification mark of the Bureau.
5.1 Control Unit : For the purpose of this scheme a (control unit), shall be taken as single charge of
the product of one or more casts heat-treated together with similar quality grading up to maximum
weight of 5 tonnes or one mother coil whichever is higher. On the basis of tests and inspection
results, decision regarding conformity or otherwise of lots of steel to the requirements of the
specification shall be taken as indicated below:
5.1.1 Chemical Composition – The chemical composition of steel is left to the manufactures
discretion.
5.1.2 Nominal Thickness and sizes - The nominal thickness and sizes for each grade shall be as
given in Table 5 and Clause 11.1, 11.2 & 11.3 respectively of the specification, unless otherwise
