c)The bidder shall appoint a Third Party Inspection Agency (TPIA) for inspection of raw materials and finished products at CA/WLA works. An indicative list of TPIAs is listed below.
i.M/S RITES Ltd
ii.M/S Metallurgical & Engineering Consultants India Ltd.
iii.M/S Bureau Veritas (India) Pvt. Ltd
iv.M/S Lloyds
v.M/S SGS India Pvt. Ltd
vi.M/S Det Norske Veritas
d)TPIA shall ensure that all steel products are manufactured from the bidder supplied semis only. All the steel products shall be embossed with the bidder’s stamp as well as CA/WLA’s name/ code.
e)All consignments shall be accompanied by following documents:
i.Correlated material test certificates of CA/WLA, counter signed by TPIA and endorsed by the bidder.
ii.All the material test certificates issued by CA/WLA shall be duly signed and stamped both by the laboratory In charge of CA/WLA and TPIA. This shall be endorsed by the bidder, with the remarks as "All the products under this test certificate are manufactured from the bidder’s raw material only."
iii.The bidder also shall certify that the testing equipment have been calibrated as per the NABL requirements.
iv.The Invoice & challan shall be issued by the bidder against each consignment with the mention of CA/WLA and also have a reference clearly linking with the bidder’s test Report and CA/WLA’s test certificate.
f)The bidder shall furnish an updated list of CA/WLA on half yearly basis or in case of new appointment / deletion of CA/WLA to NTPC.
4.MARKING
Specification, Grade, Melt number, makers emblem/code to be stamped/tagged on each bundle/coil of bars as per IS 1786.
5.INSPECTION AND CERTIFICATION
Manufacturers Test certificate (MTC) in English for each product as per IS 1786 including the following details shall accompany the product:
•Purchase Order No. (NTPC) & Test certificate No.
•Place of Manufacturing of the reinforcing steel
•Nominal diameter of the steel
•Grade of Steel
•Rolled-in marking on the steel
•Cast heat number
