Wide frame testing systems for larger fixtures and wider samples.
Testometric wide frame configurations create extra throat and working width for environmental chambers, large grips, compression platens, bulky specimens and dual-station layouts that do not fit a standard column spacing.
For tests where width and fixture clearance are the limiting factors.
A wide frame option is not just a bigger machine. It is specified when the specimen, grips, compression platens or chamber need more clearance around the force axis than a standard UTM can provide.
- Large grips, wide compression platens and bulky product fixtures.
- Environmental chamber mounting where the chamber body needs additional throat clearance.
- Composite panels, timber, foam, sheet products and wider assemblies that need open access.
- Dual-station or custom fixture layouts when the machine must support more than one test position.
Wide frame is a clearance decision first, a capacity decision second.
Use the wide-frame route when a standard frame has enough force but not enough width for the real fixture setup. That distinction matters because it can avoid over-buying a larger force machine when the issue is only access around the test axis.
| Problem in the lab | Large grip, platen, chamber or bulky specimen touches the columns | Wide frame value | More throat and operator access while retaining the required force range |
|---|---|---|---|
| Not the best fix if | The issue is vertical daylight, very long elongation or long gauge length | Better route | Long frame or horizontal tester depending on specimen handling |
| Specification proof | Send fixture width, chamber body size, sample width and clearance sketch | Acceptance check | Confirm loading axis, guard clearance, operator reach and calibration access before order |
WFX wide frame modification for X350.
Testometric lists a WFX wide frame modification for X350-5, X350-10 and X350-20 models, giving 420 mm throat space for environmental chambers, large grips or platens, or as a dual-station option. That makes it a practical upgrade for mid-force tests where fixture width is the bottleneck.
Chamber clearance
Extra width helps place environmental chambers around the test axis while preserving operator access.
Fixture clearance
Large grips, platens and custom product fixtures can be accommodated without crowding the columns.
Dual station planning
Some workflows can use wider space for station separation, fixture staging or faster operator handling.
Keep the standard Testometric measurement performance, expand the working envelope.
The live FITCO wide frame page exposes only generic blocks, so the final page keeps those platform specifications visible and ties selection to the real fixture envelope.
| Frame basis | X350 wide frame option or other Testometric platform selected by force and fixture size | Known X350 WFX throat | 420 mm throat on X350-5, X350-10 and X350-20 models |
|---|---|---|---|
| Force measurement | Better than Grade 0.5 to EN 7500-1, DIN 51221, ASTM E4 and AFNOR A03-501 | Load cell handling | Automatic identification with autoranging and electronic protection |
| Extension measurement | Full frame length measurement with 0.001 mm resolution | Speed control | Jog speed from 0.001 mm/min to maximum with fine setting increments |
| Software | WinTest Analysis for stored methods, graphs, statistics, reports and export workflows | Fixture package | Defined by grips, platens, chamber, specimen width and operator access |
Define the envelope before specifying the frame.
- Maximum specimen width, thickness, fixture width and required clearance around the force axis.
- Force range, travel range, crosshead speed, test standard and expected end point.
- Environmental chamber dimensions, platen size, grip type or custom fixture drawing if applicable.
- Operator access, guarding, report output, calibration standard and available bench or floor space.
Use the page to prevent a wrong-frame purchase.
The useful quotation question is not "what is the widest frame?" It is whether the exact sample, grip, platen and chamber package fits without compromising alignment, access or guarding.
Fixture-first layout
Build the machine envelope around actual accessory dimensions, not catalogue names. This catches column interference before procurement.
Environmental testing
For chambers, confirm door swing, cable routing, temperature hoses, extensometer access and emergency stop reach.
Dual-station planning
If a second station is planned, confirm whether it shares the load cell, needs separate fixtures, and how operators will load samples safely.
Same test control, more room for the real sample.
