Mass and uniformity of zinc coating test 7. Izod impact test 1. Wear and corrosion test: Quantify the wear and corrosion in terms of percentage reduction in diameter of the wire rope and other appliances used in mines. BIS code used for the above test: Round wire IS: 5230-1969 Reaff. 1993 Shaped wire IS: 3626-1978 2. Lubrication of wire ropes (Lubricant content) Wire ropes used in different mining operation requires lubrication. Lubrication reduces friction between inpidual wires, between strands, between coils of rope, and between the rope and other surfaces, such as sheaves and drums.

The following elements can be measured up to PPB range: C, Si, Mn, P, S, Cr, Mo, Ni, Al, Co, Cu, Nb, Ti, V, W, Pb, Sn, Mg, As, B, Zn, N Aluminium base - The following elements can be analyzed up to PPB range: Si, Fe, Cu, Mn, Mg, Cr, Ni, Zn, Ti, B, Be, Bi, Ca, P, Pb, Sn, Sr, V, Zr Copper base - The following elements can be analyzed up to PPB range: Zn, Pb, Sn, P, Mn, Fe, Ni, Si, Mg, Cr, As, Sb, Bi, Al, S, Be
Optical Emission Spectrometer 5. Hardness We have Vickers Hardness Testing, Brinell Hardness Testing and Rockwell Hardness Testing machine to determine hardness of ferro alloys as per DGMS guidelines. BIS code used for the above test: Vickers Hardness Testing : IS: 1501(pt 1) -1984 2nd rev. Reaff. 1999, IS: 1501 (Part II) 84 reaff. 1989, IS: 1501 (pt III) 87 reaff. 1999 Brinell Hardness Testing: 1500-1983 2nd Rev. Reaff. 1989 Rockwell Hardness Testing: 1586-1988 (B+C scale)
6. Mass and uniformity of zinc coating Galvanized wire rope has a wide variety of uses. In this type of rope, all of the wires are coated with pure zinc, which forms a protection against corrosion. Here we determined the mass and uniformity of zinc coating of winding rope as well as electrical cables as per DGMS guidelines. BIS code used for the above test: IS: 3975-1988 Reaff. 1992, IS: 4826-1979 Reaff. 1998, IS: 10810(pt. 41) -84Reaff.1996, IS: 4905-1968 Reaff.1996, IS: 10810 Part 40-84 Reaff. 1992 . 7. Izod impact test We have izod impact testing machine to determine the energy absorbed by the material for fracture as per DGMS guidelines. BIS code used for the above test: IS: 1598:1977 1st rev. reaff. 1999
