IS 1852 : 1985 Rolling and cutting tolerances for hot rolled steel products

1 Scope

1.1 This standard lays down rolling and cutting tolerances forhot-rolled structural steel beams, channels, equal and unequal-legangles, tee bars, bulb angles, round and square bars (other thanbars meant for fasteners), flats, plates, strips and sheets rolledfrom structural steels including medium and high strength steels.

1.1.1 A list of Indian Standards covering material anddimensions of various hot-rolled sections is given in Appendix Afor information.

1.2 This standard does not cover dimensional tolerances forcarbon and alloy constructional steel products which are covered byIS : 3739-1972.

1.3 For any specific end uses, such as shipbuilding, machinecomponents, pressure vessels, etc, special tolerances finer thanthose specified in this standard, reference shall be made to theappropriate Indian Standard if available or otherwise these shallbe as agreed to between the purchaser and the supplier.
