If the system is moved to a new machine, dropped, or undergoes significant maintenance.

The verification process outlined in the ASTM E83 PDF involves comparing the readings of the extensometer against a highly accurate reference device, known as a calibration apparatus or displacement standard. Key Steps in the Verification Procedure:

Often acceptable for materials with high elongation properties, such as plastics, elastomers, and certain composites, where absolute micro-strain precision is less critical. The Verification and Calibration Process astm e83 pdf

, with higher letters generally indicating higher permissible error. Epsilon Tech Error Limits extensometer, the error must not exceed the greater of of the value. Calibration Frequency

ASTM E83 is a standard practice established by ASTM International. It outlines the procedures for the .

It applies to instruments that indicate or record values proportional to length changes—specifically, extensometers measuring tensile or compressive strain. I can provide tailored advice on or setting

The deviation in the actual displacement measured during the test. Extensometer Class Maximum Error of Indicated Strain (Whichever is greater) Fixed Error Limit Typical Applications Class A ±plus or minus 0.1% of reading ±plus or minus Ultra-precise research, calibration of other devices Class B-1 ±plus or minus 0.5% of reading ±plus or minus Determining modulus of elasticity for metals Class B-2 ±plus or minus 0.5% of reading ±plus or minus Standard tensile testing, yield strength verification Class C ±plus or minus 1.0% of reading ±plus or minus High-elongation materials, plastics, elastomers Class D ±plus or minus 1.0% of reading ±plus or minus Rough elongation measurements The Verification Process: How It Works

Once you have the official ASTM E83 PDF, keep these practical tips in mind:

The software or technician calculates the difference between what the calibration rig actually moved and what the extensometer displayed. If the errors fall within the limits shown in the table above, the device receives its classification. Frequency of Verification Key Steps in the Verification Procedure: Often acceptable
