Measurement Risk

Measurement risk is the probability that an incorrect decision will result from a measurement. The consequences of not getting the measurement right can include: massive recalls, product failures, significant financial loss, and loss of life. Not all calibration labs are created equal. There is quite a bit of difference between force measurement labs with CMC uncertainty parameters of 0.1 %, 0.05 %, 0.02 %, 0.01 %, 0.005 % and 0.002 % of applied force. Not using the right force calibration laboratory with the capability to meet your requirements is similar to using a ruler to calibrate a gauge block. It just does not make sense. Learn more about our Accredited Force Calibration Services.

Confidence in Your Results

Confidence in your force measurement process begins with the force calibration service. We work with every customer to ensure the instruments submitted for force calibration are calibrated in the same manner they are being used. This allows our customers to replicate the calibration results in their tests. Our ISO/IEC 17025 accredited measurements are more accurate than any other commercial laboratory, which translates into lower uncertainties for you. Low uncertainties result in higher acceptance limits when using method 5 of ANSI/NCSLI Z540.3 Handbook and allow us to make more statements of conformity per the requirements of section 7.8.6.1 of ISO/IEC 17025:2017.

Truly Traceable Calibrations

Several standards may require calibration, or verification of measuring instruments with proof of traceability. The pyramid to the left, shows uncertainties increasing with each calibration step or level. From VIM 2.41 "Metrological Traceability - property of a measurement result whereby the result can be related to a reference through a documented unbroken chain of calibrations, each contributing to the measurement uncertainty.” Thus, without careful consideration of calibration uncertainty, a proper chain of traceability cannot be established. Morehouse is a primary standards laboratory, directly
traceable to SI through NIST.

Capabilities!

Morehouse primary force calibration laboratory is capable of performing ISO/IEC 17025 accredited calibration from 0.1 lbf to 2.25 million lbf (.0004 kN to 10 MN) in compression and from 100,000 lbf to 1 million lbf (4.4 kN to 4.45 MN) in tension. Our force calibration lab features the capabilities below.
Force calibration with primary deadweight standards from 0.1 lbf to 120,000 lbf (.0004 kN to 10 MN) with Calibration and Measurement Capability (CMC) better than 0.002 % of applied force in compression and tension.
Force calibration with secondary standards from 100,000 lbf to 2.25 million lbf (4.4 kN to 10 MN) with Calibration and Measurement Capability (CMC) better than 0.01 % of applied force in compression.
Force calibration with secondary standards from 100,000 lbf to 1 million lbf (4.4 kN to 4.45 MN) with Calibration and Measurement Capability (CMC) better than 0.01 % of applied force in tension.
Accredited for force calibration in accordance with ASTM E74 for Class AA, ISO 376 for Class 00, and for reporting hysteresis errors on general calibrations.
Morehouse features one of the highest deadweight calibration capabilities in the world. The only organizations with higher deadweight force measurement capability than Morehouse are National Metrology Institutes such as NIST.
Can perform calibrations using the following standards and procedures: ASTM E74, ISO 376, ASTM E2428, BS7882, single run, dual run, three run and average, increasing and decreasing forces, ANSI Z540.3 using method 6 to calculate measurement risk, and special requests.
