The first three Public Sector steel plants i.e. Bhilai, Rourkela & Durgapur were set up in collaboration with three different countries. Naturally, the equipment and other hardware installed in these plants were conforming to the standards of the respective countries. Subsequently, Bokaro was commissioned in early seventies. It was rightly called the Swadeshi Steel Plant as a substantial percentage of indigenous machinery and equipment were used in Bokaro. With TISCO & IISCO already having their own sets of specifications, there was a huge proliferation of types, sizes and even designs leading to high inventories, problems in maintenance and difficulties in procurement.With a view to overcoming the above difficulties, the Ministry of Steel appointed a Panel of Experts on Standardization of Steel Plant Equipment which recommended creation of a permanent body of experts to carry out the standardization work.
