GB/T 16825.1-2008 Verification of static uniaxial testing machines - Part 1：Tension/compression testing machines - Verification and calibration of the force-measuring system (English Version)
Verification of static uniaxial testing machines - Part 1：Tension/compression testing machines - Verification and calibration of the force-measuring system
1 Scope
This part of GB/T 16825 specifies the verification of tension/compression testing machines.
The verification consists of
——a general inspection of the testing machine, including its accessories for the force application;
——a calibration of the force-measuring system.
Note: this part of GB/T 16825 addresses the static verification of the force-measuring systems. The calibration values are not necessarily valid for high-speed or dynamic testing applications. Further information regarding dynamic effects is given in the Bibliography.
