ASTM D256 · D6110 — Notch-Depth Measurement

Micro-meter Jig (Notch Measurement)

A digital micro-meter jig that measures the depth of the 'V' notch machined by the Motorized Notch Cutter — verifying notch-depth accuracy for valid Izod and Charpy impact tests, per ASTM D256 and D6110.

  • Measures V-notch depth per ASTM D256 & D6110
  • Mitutoyo digital gauge — up to 12.50 mm, 0.01 mm resolution
  • Depth measurement range 0.00–3.00 mm
  • Battery operated; electroless nickel-chrome plated
Made in IndiaISO 9001:2015CE CertifiedExported to 60+ countries
Overview

Confirm the notch before you trust the impact result

Izod and Charpy impact results depend on a precise notch — a notch that is too deep or too shallow shifts the result. After the notch is cut, its depth must be verified, and that is what this jig does.

International Equipments builds a micro-meter jig with a Mitutoyo digital gauge (up to 12.50 mm, 0.01 mm resolution) and a depth-measurement range of 0.00–3.00 mm, on a nickel-chrome-plated base. It pairs with the Motorized Notch Cutter and the Izod/Charpy tester. Manufactured in Mumbai.

FAQ

Frequently asked questions

What does the micro-meter jig measure?
The depth of the 'V' notch machined into an Izod or Charpy specimen, to confirm it meets the ASTM D256 / D6110 requirement before impact testing.
Why is notch depth so important?
Impact strength is very sensitive to notch geometry — an out-of-tolerance notch depth gives a misleading result, so it is verified after cutting.
What gauge is used?
A Mitutoyo digital gauge with a range up to 12.50 mm and 0.01 mm resolution, with a depth-measurement range of 0.00–3.00 mm.
Is it battery operated?
Yes — the jig is battery operated and has an electroless nickel-chrome-plated base.
