FAQs

Which 3-Point Bending Fixture Do I Need for My Test Force and Span?

Choose by the force your specimens need and the span your method calls for, because the four main fixtures in the range rise in both at once: 20 kN over a span of up to 200 mm, 50 kN over 280 mm, 100 kN over 340 mm and 300 kN (67,443 lbf) over 400 mm.

Specimen width steps up with them. The 20 kN fixture takes specimens up to 30 mm wide; from 50 kN, where metal and construction samples take over from plastics, the limit is 80 mm, and 90 mm at 300 kN.

Tile adhesive, raised pavement markers and chamber testing each have a dedicated fixture, and for those jobs the specimen decides the model rather than the force.

Share the specimen size, material and expected peak force on our quote request form, and we will match the fixture and roller set to your frame.

Which Flexural Standards Do the 3-Point Bending Fixtures Support?

The range is built to five standards: ASTM D790, ISO 178 and GB/T 9341 for the flexural properties of plastics, ISO 14125 for fiber-reinforced plastic composites, and ASTM E290 for bend tests that check ductility. It covers thermoplastics, composites, metals and laminated structures.

The plastics and composite methods load a bar at mid-span between two supports and calculate flexural strength and modulus from the force and the deflection. They set the span from the specimen thickness, so an adjustable span lets one fixture serve several thicknesses.

ASTM E290 works differently. The specimen, usually metal, is bent through a specified angle and the outside of the bend is then checked for cracks, so the result shows whether the material has the ductility its specification requires.

How Do the 3-Point Bending Fixtures Mount on a Universal Testing Machine?

The fixtures connect through pins at the upper and lower grip. The 10 kN and 20 kN fixtures use Ø10 mm pins, and the 50 kN, 100 kN and 300 kN fixtures use Ø18 mm pins for heavy-load frames. The compact 10 kN version is sized for small frames.

Weight rises with capacity. The lower half of the 20 kN fixture weighs 5.3 kg (12 lbs), while the lower half of the 300 kN fixture weighs 36.0 kg (79 lbs) and is 500 mm wide overall, so plan how it will be lifted into place.

The fixtures are designed for our NG-EML and SHM universal testing machines. The fixture and the frame both have to cover your peak force, so check the rating of the load cell as well as the fixture when you plan a test.

Which Loading Nose and Roller Sizes Do the 3-Point Bending Fixtures Use?

Roller size grows with capacity. The 20 kN fixture uses an R5 loading nose with R2 and R5 support rollers, the 50 kN and 100 kN fixtures use Ø20 mm loading and support rollers, and the 300 kN fixture uses Ø30 mm rollers.

The loading nose and supports carry the whole test force along narrow contact lines, so their radius affects the result. Plastics standards such as ISO 178 fix the radius of the loading edge and supports and change the support radius with specimen thickness; the R2 and R5 support rollers of the 20 kN fixture cover both cases.

Metal and construction samples at 50 kN and above need larger rollers to spread a much higher force without denting the specimen at the contact points. Noses and rollers can be changed, and we make other radii and diameters to order, so one fixture can follow the geometry of a different standard.

Which 3-Point Bending Fixture Is Built for Testing in a Temperature Chamber?

The short-span fixture is rated from -70°C to +350°C for bending plastics, composites and ceramic materials inside a thermal chamber. It carries up to 10 kN, while the rest of the range is built for ambient conditions.

Testing at temperature matters because polymers stiffen in the cold and soften as they warm, so a modulus measured at room temperature says little about a part that works in a freezer or next to a heat source.

The span adjusts up to 90 mm on a base 190 mm wide, a compact footprint for a chamber, and the short span suits small specimens too short to bridge a longer one. Specimens up to 30 mm wide fit, with an R5 loading roller and R5 and R2 support rollers, and we can supply other roller sizes to your requirements.

How Does the 3-Point Bending Fixture for Ceramic Tile Adhesive Work?

It bends a thin strip of cured tile adhesive in three-point loading over a 200 mm span, and it is rated to 10 kN (2,248 lbf).

The deflection the strip reaches before it cracks is how the deformability of a tile adhesive is judged. That property matters wherever the substrate moves with temperature or shrinkage, because an adhesive that cannot follow the movement lets the tiles crack or debond.

The fixture takes the strip sizes commonly used in tile adhesive testing, 280 × 45 × 5 mm and 300 × 45 × 3 mm, and its loading nose and support rollers apply the load evenly across the strip width.

How Does the Marker Bending Fixture Test Raised Pavement Markers?

It holds the marker in a support shaped for its body and loads it in bending, at up to 20 kN (4,496 lbf) over a span that adjusts to 200 mm. Raised pavement markers are the small reflective markers bonded to the road surface, and their shape calls for a support made for the marker rather than the flat rollers used for a bar.

A dual-height, dual-width design fits many marker sizes. The upper grip is 85 mm high and 150 mm wide, and the lower grip is 120 mm high and 220 mm wide.

Markers carry wheel loads for years once they are on the road, so a flexural test on the finished product is a practical check for transportation and infrastructure laboratories. The fixture weighs 6.5 kg (14 lbs) and suits standard universal testing machines.

Snubbing grips, also known as capstan grips, are designed for tensile testing of wires, cables, ropes, textile strips, and geogrids that can slip or break in standard clamps. By wrapping the specimen around curved surfaces, they increase friction and reduce grip-end failures. These fixtures help laboratories achieve safer, more repeatable axial loading for high-strength or flexible materials.

Side-Action Tensile Grips

Side action tensile grips provide quick, secure clamping for films, thin sheets, textiles, fine wires, polymer strips, and other flexible specimens on universal testing machines. Available in manual lever and screw-action configurations, they support different force ranges, jaw surfaces, and specimen sizes. Their side-clamping design helps improve alignment, reduce slippage, and speed up routine tensile testing in QC and R&D labs.
