LS-U/V Manual Notch Pulling Machine for Impact Test Specimens

Overview

In material notch impact testing, the precise fabrication of V-shaped or U-shaped notches is a critical factor for the validity of the test. The LS-U/V manual notch pulling machine provides an ideal solution that guarantees 100% qualified production of V-shaped notches, as well as U-shaped notches of 2mm and 5mm sizes.

This machine features a manual operation mechanism and can be configured with either V-shaped or 2mm U-shaped notch cutters based on user requirements. It performs one-time forming of specimen notches with simple, reliable operation. The produced V-shaped and 2mm U-shaped notches fully comply with standard:

ISO 148-1:2016 Metallic materials — Charpy pendulum impact test — Part 1: Test method

ISO 148-2:2016 Metallic materials — Charpy pendulum impact test — Part 2: Verification of testing machines

ASTM E23-18 Standard Test Methods for Notched Bar Impact Testing of Metallic Materials

DIN 50115 Testing of metallic materials — Impact bending test — Test specimens (DVM specimen requirement)
