BIS CERTIFICATION FOR STEEL RIVET BARS
IS 1148:2009

This standard specifies the requirements for medium and high tensile rivet bars with diameters up to 40 mm for structural applications.

IS 8910 specifies the general requirements for the supply of rivet bars for structural purposes. Rivet bars must be made from steel that has been produced using open-hearth, electric, duplex, basic oxygen, or a combination of these processes. If the manufacturer employs another process, the purchaser's prior approval should be obtained. Steel must be delivered semi-killed or killed. Unless otherwise specified, bars must be supplied in hot-rolled conditions. Rivet bars must be well and cleanly rolled to the specified dimensions and tolerances. The finished material must be free of surface and internal flaws that would be detrimental to the material's end-use.

TESTS

The following test shall be carried out as per the specified standard.

• Tensile test
• Bend test
• Shear test
• Hot compression test
• Chemical composition

Packing and Marking:

Rivet bars must be securely bundled, and a metal tag attached to each bundle must be marked with the following information: a) the manufacturer's name or trade-mark, and b) a cast number or identification mark that allows the steel to be traced back to the cast from which it was made. The Standard Mark (ISI Mark) may also be applied to the material.

Manufacturers must obtain a BIS license from the Bureau of Indian Standards to use a standard mark (ISI Mark). The Bureau grants a license based on a successful assessment of manufacturing infrastructure, production process, and quality control and testing capabilities during a visit to its manufacturing premises.
