Flexing & Cable Test Equipment
ED&D flexing and cable test equipment supports repeatable cord anchorage torque testing and continuous bending / flexing testing for electrical appliances, flexible cords, cord sets, hand-held tools, and related products. This product family includes the F20 Cord Anchorage Torque Device and the Series F39 Flexibility Test Swivel Machine for standards-driven workflows associated with IEC 60335, IEC 60227, IEC 60745, and UL 745.
Cord Anchorage Evaluation
Test resistance to applied torque on non-detachable flexible cords using a dedicated cord-anchorage device.
Continuous Bending Tests
Run repeatable flexing tests on flexible cables, cord sets with plugs, hand lamps, and electric tools using a swivel-style flexing machine.
Built for Method-Specific Testing
Choose the equipment based on whether the standard calls for torque resistance at the cord anchorage or repeated bending of the cable assembly.
Tell us the exact standard, cable diameter, specimen type, and whether you need cord anchorage torque testing or continuous flexing / bending testing.
Flexing and Cord Anchorage Testing for Flexible Cords and Cable Assemblies
Flexing and cable testing is used to evaluate how a flexible cord, cable assembly, or cord anchorage performs under repeated mechanical stress. Depending on the governing method, that stress may be applied as a defined torque at the cord anchorage or as a continuous bending / swivel motion over repeated test cycles.
ED&Dās flexing and cable test equipment family covers both of those needs. The F20 Cord Anchorage Torque Device is intended for torque-resistance testing on non-detachable flexible cords, while the Series F39 Flexibility Test Swivel Machine is used for repeated bending tests on flexible cables, cord sets with fitted plugs, electric tools, and hand lamps.
The supplied product information ties this equipment to IEC 60335, IEC 60227, IEC 60745, and UL 745 workflows. Final suitability still depends on the exact clause, specimen geometry, conductor count, cable diameter, load arrangement, and cycle conditions required by the governing method.
Important standards note: cable testing is only meaningful when the test motion, conductor loading, clamping arrangement, torque, and specimen preparation all match the exact method required by the governing standard.

Construction details: base plate and bearing appliance in papyrus-white structure varnish, with fastening device and other parts browned, nickel-plated, or stainless steel as described in the supplied product information.
Standards positioning: used for cord anchorage torque testing associated with IEC 60335.
Selection note: confirm cord diameter, torque requirement, and appliance anchorage configuration before choosing the F20 for a specific test setup.
Series F39 Flexibility Test Swivel Machine
The Series F39 Flexibility Test Swivel Machine is used for continuous bending tests on flexible cables, cord sets with fitted plugs, electric tools, and hand lamps. In its standard version, the machine allows the simultaneous testing of two samples, which can reduce test time and simplify the current-test circuit by looping through the cables.
Product Details
- For continuous bending tests on flexible cables and cord sets with fitted plugs
- Also used for electric tools and hand lamps
- Standard version tests two samples simultaneously
- Supports simplified current-test looping through the cables
- Reinforced version available for cables over 10 mm diameter
- Additional clamping devices can be adapted to specific sample shapes and types
Standards positioning: used for repeated flexing tests associated with IEC 60335, IEC 60227, IEC 60745, and UL 745.
Configuration note: for larger cable diameters, unusual plug geometry, or non-standard specimen shapes, confirm whether reinforced construction or custom clamping devices are required.
Series F39 Model Reference
| Model | Number of Current Loaded Conductors | Voltage Between the Current Loaded Conductors | Additional Slightly Current Loaded Conductors | Current Load Unit |
|---|---|---|---|---|
| F39.52 | 2 | 230 V | changeable: 0 or 1 | A |
| F39.53 | 3 | 3 x 400 V | changeable: 0, 1 or 2 | A |
| F39.56 | 2 | 230 V | changeable: 0 or 1 | B |
| F39.57 | 3 | 3 x 400 V | changeable: 0, 1 or 2 | B |
Which Flexing or Cable Test System Is Right for Your Lab?
| Equipment | Primary Use | Test Motion | Best Fit |
|---|---|---|---|
| F20 | Cord anchorage torque testing | Applied torque at the anchorage | Methods focused on non-detachable flexible cord retention and torque resistance |
| Series F39 | Continuous flexing / bending testing | Repeated swivel and bend motion | Cables, cord sets, tools, and hand lamps requiring repeated flexing evaluation |
Selection guidance: choose the F20 when the method is focused on torque resistance at the cord anchorage, and choose the Series F39 when the method requires repeated bending or flexing of the cable assembly itself.
Frequently Asked Questions
What is the difference between cord anchorage testing and cable flexing testing?
Cord anchorage testing evaluates how well the cord is retained and resists applied torque at the appliance entry point, while cable flexing testing evaluates how the cable assembly performs under repeated bending motion.
What does the F20 torque device test?
The F20 tests the resistance to torque of cord anchorages on electrical appliances with non-detachable flexible cords.
What does the Series F39 test machine do?
The Series F39 performs continuous bending tests on flexible cables, cord sets with fitted plugs, electric tools, and hand lamps.
Can the F39 test more than one sample at a time?
Yes. In its standard version, the F39 allows simultaneous testing of two samples.
What if the cable is larger than 10 mm in diameter?
The supplied product information states that a reinforced version can be supplied for cables over 10 mm in diameter.
Can one machine cover every cable test method?
No. Different standards may call for torque, pull, bend, swivel, or current-loading arrangements, so the correct machine depends on the exact method.
Send the exact standard, specimen type, and cable construction, and we can help narrow the right torque or flexing system.
