Three Strikes, One Question: Does It Shatter or Survive?
Impact Resistance Testing across Izod, Charpy, and drop-weight loading at our Oragadam laboratory — sudden-impact evaluation for medical device, industrial, and automotive testing programmes.
Call 90876 86986 WhatsApp UsA component that survives a slow bend can still shatter the instant it’s actually dropped, struck, or hit, and no single impact method captures every way that sudden failure can happen.
Impact Resistance Testing is the umbrella that covers all three standard sudden-loading geometries in one accredited scope, because a material that performs well under one impact method can still fail badly under another. Our capability at the Oragadam laboratory runs pendulum and falling-weight instruments side by side, letting a single sample submission cover everything from a small notched bar to a full moulded housing. Izod Testing clamps the specimen vertically and strikes it with a swinging pendulum, the standard US method for characterizing notch sensitivity in rigid plastics.
Charpy impact testing supports the specimen horizontally at both ends instead, striking it at the centre — a distinct loading geometry that some international specifications and a wider range of material grades are built around, including materials too brittle or too thin to hold securely in an Izod clamp. Drop-weight impact testing takes a completely different approach again, releasing a falling dart or striker onto a flat sheet, film, or finished moulded part from a defined height, reproducing the kind of accidental impact a packaged product or housing actually experiences in shipping and handling rather than a small standardized test bar, which is exactly why drop weight impact testing is treated as its own distinct checkpoint.
The same pendulum and falling-weight instruments that support our medical device work are exactly what automotive testing programmes rely on too — bumper fascia, interior trim, and connector housings are qualified against the same three impact geometries, just referenced to different industry-specific standards on request. That shared equipment base is why manufacturers moving between medical device work and other industrial programmes find it faster to qualify a material once at Kiyo R&D Lab rather than re-establishing a new lab relationship for every new vertical. Manufacturers across medical device, consumer electronics, and industrial packaging bring their programmes here because a single missed impact reading doesn’t surface as a data-sheet footnote — it surfaces as a shattered housing corner, a cracked clip, or a part that fails the very first time it’s actually dropped. Running the full impact panel under one accredited scope at Oragadam, with reports formatted for direct regulatory submission, is what turns three separate strike results into evidence your quality team can actually stand behind.

Frequently Asked Questions
What does Impact Resistance Testing cover? +
It covers all three sudden-impact geometries in one accredited scope, referenced to ASTM D256/ISO 180, ISO 179/ASTM D6110, and ASTM D5628/ISO 6603.
When would I need Charpy instead of the vertical-clamp method? +
Some international specifications and material data sheets are built around the horizontally-supported Charpy geometry, and it also suits materials too brittle or too thin to hold securely in a vertical Izod clamp, so requesting both from one visit covers either reference format.
Why is drop weight impact testing run separately from Izod and Charpy? +
A falling dart or striker reproduces the kind of accidental impact a packaged product or housing actually experiences in shipping and handling, which is a different failure mode from a small standardized pendulum bar and can’t be predicted from Izod or Charpy data alone.
Do you support automotive testing alongside medical device work? +
Yes. The same pendulum and falling-weight instruments that support our medical device work are exactly what automotive testing programmes rely on for bumper fascia, trim, and connector housings, just referenced against different industry-specific standards on request.
