Precision cutting die for GOST 19109 Type A notched Izod Bar specimens
This Universal Grip die cuts the notched Izod bar (izod impact specimen) defined in GOST 19109: Plastics - Determination of Izod impact strength. Rectangular bar with a single V-notch, struck by a pendulum in a cantilever (Izod) setup. Notch Type A gives the standard notched Izod impact strength.
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 GOST 19109 Type A profile.
GOST 19109 Type A specimen dimensions
The die is cut to the nominal profile in GOST 19109: length 80 ± 2 mm, width 10.0 ± 0.2 mm, thickness 4.0 ± 0.2 mm, notch depth 2.0 mm (remaining 8.0 ± 0.2 mm) and notch angle / tip radius 45° ± 1° / 0.25 ± 0.05 mm. Always check your current edition of the standard for tolerances and the test procedure.
Where it is used
Typical uses for GOST 19109 Type A specimens include impact-modified polymers, engineering plastics, low-temperature toughness checks and resin certification.
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.

GOST 19109 Type A Cutting Die FAQ
What is the GOST 19109 test used for?
Rectangular bar with a single V-notch, struck by a pendulum in a cantilever (Izod) setup. Notch Type A gives the standard notched Izod impact strength.
What are the GOST 19109 Type A specimen dimensions?
The die cuts the nominal GOST 19109 profile: length 80 ± 2 mm, width 10.0 ± 0.2 mm, thickness 4.0 ± 0.2 mm, notch depth 2.0 mm (remaining 8.0 ± 0.2 mm) and notch angle / tip radius 45° ± 1° / 0.25 ± 0.05 mm. These values come from the standard; check your current edition for tolerances.
Hardened steel or ribbon steel: which GOST 19109 Type A 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 GOST 19109 Type A 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.
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 GOST 19109 Type A 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.
