CMC Workbook for ASTM E74 Uncertainty

For tension and compression calibration, intersperse the loadings. There are two methods to calculate deflection: With slight modification, the uncertainty sheet could be used for instruments calibrated in accordance with another test method or standard.

The procedures are useful to users of testing machines, manufacturers and providers of force-measuring instruments, calibration laboratories that provide the calibration of the instruments and the documents of traceability, service organizations that use the force-measuring instruments to verify testing machines, and testing laboratories performing general structural test measurements. This corresponds to a Be sure to re-exercise the UUT prior to any change in setup. The r74 calibration steps include stabilization, preparation, the calibration procedure itself, and data analysis.


There are three criteria for the lower load limit: Zero cannot be a test point Per Section 7. Practices E74 describes how these astn instruments are to be calibrated.

Instruments used as Class A devices i. The FDA wants medical device manufactures to succeed, new technologies in supply chain managment.

May the Force Be With You | Quality Digest

ashm Quality with a Big Q. This low force must be greater than the resolution of the device multiplied by for Class A or for Class AA devices. Inside Quality Digest Live for October 19, r74 Criteria for Lower Load Limit. Henry Zumbrun is president of Morehouse Instrument Co. Apply the third series of forces Run 3. Method B deflection readings are calculated as the difference between readings at the applied force and the average or interpolated zero force readings before and after the applied force readings.

Practices E4 has been written to provide a practice for the force verification of these machines. Allow the unit under test UUT to come to room temperature. Method B Deflection readings should be calculated as the difference between readings at the applied force and the average or interpolated zero force readings before and after the applied force readings.


Wanna do business with a company who focuses on what matters most? It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

Procedures are included for the following types of instruments: This is size-dependent and can take 24 to 48 hours. Other metric and inch-pound values are regarded as equivalent when required. Everything we do, we believe in changing how people think about force and torque calibration.

IoT platform uncovers insights into tooling optimization to enhance machine reliability for customers. Apply the second series of forces Run 2. Any instrument that is either modified or repaired should be recalibrated.

Anyone calibrating in accordance with the ASTM E74 standard should first purchase a full copy of the standard here. Assessing the Health of a Measurement System.
