Calibration

ABS Instruments became an NABL accredited calibration laboratory in the year 2004 for the calibration of mechanical testing machines and related instrumentation. 

We have over 20 years of experience in the field of calibration and servicing of mechanical testing machines. Our engineers are experienced and trained in order to provide you the best service possible and keep you tests up and running. 
 
Our NABL scope for calibration includes the following:
 
1. Impact Testing Machines: 
We have obtained the NABL accreditation for the calibration of the impact testing machines as per ISO 148:2008, ASTM E 23-07, ASTM D 256-05, D 6110-4 and ISO 13802;1999. We calibrate both IZOD and Charpy impact testing machines. Our Clinometer is imported from Switzerland. 
 
2. Extensometers:
With the arrival of the revised standards and due to the recognition of the importance of extensometers in measurement of strain, it has now become mandatory to calibrate extensometers. 
We calibrate extensometers used on Universal Testing Machines as per ASTM E8310a and IS 12872:1990. Our calibration master is imported from Switzerland. We can calibrate extensometers with resolutions of both 0.1 micron and 1 micron. 
 
3. Calibration of Displacement:
We can calibrate the displacement of the cross head as per ASTM E 2309-05. We have the facility for calibration of the displacement of the UTM cross head as well as that of Actuators.
Our master calibration equipment is imported from Switzerland. It has a resolution of 1 micron and its encoder is directly in line with the cross head of the UTM ensuring a very high degree of sensitivity and repeatability.
 
4. Calibration of load cells in Universal Testing Machines:
We calibrate Universal Testing Machines as per IS 1828-2005, (PART-1) and ISO7500.
We have NABL accreditation for the calibration of Load Cells of Universal Testing Machines in both Compression mode (up to 2000 kN) and Tension mode (up to 1000 kN). 
 
5. Calibration of Hardness Testing Machines:
a. Micro Vickers Hardness Testing Machines:
We calibrate Micro Vickers hardness testing machines using standard test blocks as per IS 1754:2002. We have the NABL accreditation for the onsite calibration of Micro Vickers hardness testing machines. Our test block is imported from Europe with traceability to UKAS. 
 
b. Rockwell Hardness Testing Machines:
We calibrate Rockwell hardness testing machines using standard test blocks as per the standard IS 1586:2000. We have the NABL accreditation for the calibration of Rockwell and Rockwell Superficial hardness testing machines. Our test blocks are calibrated directly at National Physical Laboratory, New Delhi. 
 
c. Vickers Hardness Testing Machines:
We calibrate Vickers hardness testing machines using standard test blocks as per IS 1754:2002. We have the NABL accreditation for the calibration of Vickers hardness testing machines from 1 kg to 50 kg. We can provide the onsite calibration for the same. Our test blocks are calibrated directly at National Physical Laboratory, New Delhi. 
 
d. Brinell Hardness Testing Machines:
We calibrate Brinell hardness testing machines using standard test blocks as per the standard IS 2281:2005 and by using load cells and dynamometers as per IS 2281:2005. We have NABL accreditation for both the load calibration and indirect verification of Brinell hardness testing machines for onsite verification. 
 
e. Shore Hardness Testing Machines:
We calibrate Shore hardness testing machines using a check device as per ASTM D 2240-05. We have facility for calibration of Shore A and Shore D durometers with NABL accreditation. Our calibration master is imported from Germany and is according to ASTM standards. Our master equipment is calibrated at Germany and is traceable to PTB Germany. 
 
f. We also have the facility to calibrate IRHD hardness testing machines.
