Onsite Calibrations for Hardness Testers

Hardness Tester Calibration Services

Applied Technical Services has the capability to calibrate a variety of Hardness Testers on-site at your facility. ATS uses indirect verification per the applicable ASTM Standard.

  • Rockwell Hardness
  • ASTM E18
  • NIST Traceability
  • Microhardness Testers
  • Knoop Testers
  • Vickers Testers
  • Brinell Hardness Testers
  • NVLAP Certified Blocks

We offer calibration of the following Hardness Testers:

  • Standard Rockwell Hardness Testers which includes C, B, and A Scales. To certify your Standard Rockwell Hardness tester to the current revision of ASTM E18, you are required to have certified penetrators. If certified penetrators are not available, we can certify your tester to the previous revision. We offer NIST Traceability on C Scale only.
  • Superficial Rockwell Hardness Testers which includes 15, 30, 45 N"T Scales. To certify your Superficial Rockwell Hardness tester to the current revision of ASTM E18, you are required to have certified penetrators. If certified penetrators are not available, we can certify your tester to the previous revision. We offer NIST Traceability on C Scale only.
  • Twin Scale Hardness Testers which include C, B, and A Scales plus 15, 30, 45 N"T Scales. To certify your Superficial Rockwell Hardness tester to the current revision of ASTM E18, you are required to have certified penetrators. If certified penetrators are not available, we can certify your tester to the previous revision. We offer NIST Traceability on C Scale only.
  • Microhardness Testers are calibrated with NVLAP certified blocks and are calibrated in accordance with the latest revision of ASTM E384. ATS can calibrate both Knoop and/or Vickers Testers.
  • Brinell Hardness Testers (500, 1500, and 3,000 kg loads) are calibrated with NVLAP certified blocks and are calibrated in accordance with the latest revision of ASTM E10. Current revision of E10 requires the tester to have carbide indenters. ATS will be unable to calibrate a tester that only has steel indenters.
