4.3 TEST CERTIFICATE- For each consignment of BIS Certified cast billet ingot, billets,

blooms and slabs (including continuously cast) conforming to IS 2830, there shall be testcertificate which shall contain the Standard Mark, the cast number, grade designations and the

corresponding test results (See Annexure I).

5. MANUFACTURER-

5.1 Steel shall be manufactured by any process of steel making except the bassemer process. It

may be followed by secondary refining.

5.1.1 Steel shall be supplied semi-killed or killed. Rimming steel may also be supplied subject to

a special agreement between the purchaser and the manufacturer.

5.2 Carbon steel cast billets ingots, billets, bloom and slabs (including continuously cast) may

also be supplied in copper-bearing quality. In which case steel shall be designated with a suffixCu.

6. SUPPLY OF MATERIAL- General requirements relating to supply of steel shall conform to

IS 8910.

7 LEVELS OF CONTROL
