Precision cutting die for ISO 527-2 Type 5A small Dumbbell specimens
This Universal Grip die cuts the small Dumbbell Type 5A (tensile specimen) defined in ISO 527-2: Plastics — Determination of tensile properties — Part 2: Test conditions for moulding and extrusion plastics. ISO 527-2 defines tensile test specimens and conditions for moulding and extrusion plastics, building on the general principles of ISO 527-1. Type 5A is used for plastics with high elongation (elastomer-like behavior) where a small specimen is needed.
We make it in two styles so the die suits the material you cut. The one-piece hardened steel die is machined from a single piece of steel and holds its edge on rigid & semi-rigid plastics, filled compounds, rubber, sheet & film from 0 to 5 mm thick. The ribbon steel (steel-rule) die uses a precision-bent hardened rule in a laser-cut plywood base with a foam ejection pad, an economical choice for rubber, elastomers, TPE, foams, soft plastics & films up to 3 mm. Both cut the same ISO 527-2 Type 5A profile.
ISO 527-2 Type 5A specimen dimensions
The die is cut to the nominal profile in ISO 527-2: overall length (min) 75 mm, width of ends 12.5 ± 1 mm, length of narrow section 25 ± 1 mm, width of narrow section 4.0 ± 0.1 mm, transition radius (small) 8.0 ± 0.5 mm, gauge length 20.0 ± 0.5 mm and thickness (min) 2 mm. Always check your current edition of the standard for tolerances and the test procedure.
Type 5A compared with other ISO 527-2 dies
Type 1B: 10.0 × 60.0 mm narrow section, 150 mm overall length
Type 1BA: 5.0 × 30.0 mm narrow section, 75 mm overall length
Type 1BB: 2.0 × 12.0 mm narrow section, 30 mm overall length
Type 5A: 4.0 × 25 mm narrow section, 75 mm overall length (this die)
Type 5A sits mid-range among the 6 ISO 527-2 profiles we make.
Where it is used
Typical uses for ISO 527-2 Type 5A specimens include injection-moulded parts, extruded sheet & profiles, resin qualification and filled & reinforced compounds.
Cutting specimens with the die
Most labs run it on a manual arbor press, but it also fits pneumatic and hydraulic sample-cutting presses, and with an adapter it can cut specimens directly on a universal testing machine. Tell us your press make and model and we will match the mounting. Send us a sample of your material and we will make test cuts free of charge, so you can confirm the edge quality before you order. Hardened dies can be re-sharpened with our die sharpening tool.

ISO 527-2 Type 5A Cutting Die FAQ
What is the ISO 527-2 test used for?
ISO 527-2 defines tensile test specimens and conditions for moulding and extrusion plastics, building on the general principles of ISO 527-1. Type 5A is used for plastics with high elongation (elastomer-like behavior) where a small specimen is needed.
What are the ISO 527-2 Type 5A specimen dimensions?
The die cuts the nominal ISO 527-2 profile: overall length (min) 75 mm, width of ends 12.5 ± 1 mm, length of narrow section 25 ± 1 mm, width of narrow section 4.0 ± 0.1 mm, transition radius (small) 8.0 ± 0.5 mm, gauge length 20.0 ± 0.5 mm and thickness (min) 2 mm. These values come from the standard; check your current edition for tolerances.
Hardened steel or ribbon steel: which ISO 527-2 Type 5A die should I choose?
For rigid and semi-rigid plastics, filled compounds and sheet up to 5 mm, choose the hardened steel die. The ribbon steel die is the economical option for soft plastics and films up to 3 mm.
Which press do I need for the ISO 527-2 Type 5A die?
The die fits manual, pneumatic and hydraulic sample-cutting presses. On our arbor press it mounts with a lateral screw, and an adapter lets it run on a universal testing machine. Tell us your press make and model and we will match the mounting.
How do I grip and measure ISO 527-2 Type 5A specimens?
Hold the wide ends in wedge grips or pneumatic grips so the specimen is loaded straight along its axis. The gauge length is 20.0 ± 0.5 mm; our marking tool applies repeatable gauge marks for video extensometers.
Which other ISO 527-2 dies do you make?
We also make cutting dies for Type 1A, Type 1B, Type 1BA, Type 1BB and Type 5B, each in hardened and ribbon steel.
Can you make test cuts on my material?
Yes. Send us a sample of your sheet and we will make test cuts free of charge, so you can see the edge quality and confirm the right die style before you order.
Can you make a custom or multi-cavity ISO 527-2 Type 5A die?
Yes. We make custom profiles, multi-cavity dies and nick or notch features on request. Send the drawing or standard, your material and thickness, and your press model.
