Metallic materials - Verification of static uniaxial testing machines - Part 2: Tension creep testing machines - Verification of the applied force (ISO 7500-2:2006); English version of DIN EN ISO 7500-2:2007-04
This part of ISO 7500 specifies the verification of testing machines used for uniaxial creep testing in tension in accordance with ISO 204.
The verification consists of
— a general inspection of the testing machine, and
— a verification of the force applied by the testing machine.
This part of ISO 7500 applies to dead-weight machines, lever-type creep testing machines and direct-spring-loading machines.
Machines with a force-measuring system1) should be verified in accordance with ISO 7500-1, Metallic materials — Verification of static uniaxial testing machines — Part 1: Tension/compression testing machines — Verification and calibration of the force-measuring system.
