Proving Rings are precision load measuring devices machined from special forged steel and are properly heat treated to give maximum sensitivity and durability. Every Proving Ring is fitted with a dial gauge of 0.002 mm sensitivity and is supplied in a wooden/ thermocol case complete with a calibration chart.
Three types of proving rings are available viz Integral Proving Rings, clamped bosses proving ring and Tension-Compression Proving Rings.
These Proving rings have clamped bosses and are available in the range of 0.5kN – 100kN. repeatability and accuracy of all the rings confirm to IS4169:1988
Cat No. Capacity

HSC30.210 1.0 kN
HSC30.215 2 kN
HSC30.220 2.5 kN
HSC30.225 5 kN
HSC30.230 10 kN
HSC30.235 20 kN

Integral Proving Rings
These Proving rings have integral loading bosses forged and machined along with the ring. These bosses can not shift their position to cause mis-alignment which may result in loss of accuracy These rings are manufactured up to 3000kN capacity.

Note : Proving Rings of capacity 1000 kN and above are provided with loading platens.
These rings can be used both in tension as well as compression. The bosses of these rings are integral and have male threads for fixing to the tensile testing machine. Female threaded blind caps are provided on both sides for its use as compression proving rings. The capacity of these rings varies from 1kN to 100kN

Note : Proving Rings with capacities other than specified here, can also be manufactured on specific request. On demand, the rings from 50 kg to 100 tonne capacity can be supplied with N.P.L. certificate, and from 25 tonne to 300 tonne capacity with N.C.C.B.M. (National Council For Cement & Building Materials) certificate at extra cost.
