Tensile Testers
Define the force, extension and movement checks needed for your tensile testing system before requesting a calibration quotation.
Overview
Tensile testing systems measure how a specimen responds to an applied pulling force. The force indication, an extensometer’s strain measurement and the movement of the crosshead are different measurement functions. A check of one channel does not automatically establish the performance of the others.
A useful enquiry describes the measurements used in your actual tests, rather than only the machine’s maximum capacity. Include the load cells, working forces and test method so the proposed scope can be reviewed. Confirm the functions, ranges and verification method that RTS can support before booking.
What to include in your enquiry
- Machine manufacturer, model, serial number and rated frame capacity.
- Each load cell’s identification and capacity, including interchangeable cells.
- Forces normally used and whether tension, compression or both directions are required.
- Extensometer type and gauge length, if strain measurement needs checking.
- Any crosshead travel or speed checks required by your test method.
- Applicable test specification, previous results and the site or equipment location.
Confirm before booking
- Confirm the measurement channels and operating ranges included in the RTS quotation.
- Agree the verification method, acceptance criteria and any required reporting or accreditation scope.
- Confirm access, loading fixtures and the arrangements needed for the agreed work.
Common questions
- Does force calibration also verify the extensometer?
- No. The load cell reports force, while an extensometer measures specimen extension or strain. Include the extensometer separately if your test method relies on it, and confirm the required scope with RTS.
- Should I provide only the machine’s maximum capacity?
- Provide the frame and load-cell ratings, but also the forces you normally measure. These details help identify relevant verification points; the machine’s headline capacity alone does not describe your working requirements.
