BIS has revised the Indian Standards on Petrol (IS 2796) and Diesel (IS 1460) as per BS VI fuel norms. So far, these standards covered fuel requirements based on emission norms upto BS IV. With a view to conserve natural resources as well as to reduce pollution, Government has decided to implement BS VI emission norms in Delhi NCR from 1 April 2018. In rest of the country these will be implemented from 1 April 2020.

Accordingly, BIS being the National Standards Body of India, revised these standards on Petrol and Diesel incorporating BS VI fuel specifications.

Society of Indian Automobile Manufacturers (SIAM) has welcomed the move of BIS to revise the Indian Standards on petrol and diesel based on the BS-VI fuel norms.

The revised standards will improve the environment and reduce respiratory problems due to reduction in permissible sulphur content which will also reduce emission of nitrogen oxides (NOX). These standards also permit increased blending of Ethanol in Petrol and Bio-diesel in Diesel which will help in conservation of natural resources and reduction in import of Crude.
