If You Want to Know and Purchases ASTM Impact Testing Machines. Then, You Can Contact us Shortly and Check Features. We added here detailed specifications for the ASTM Impact Testing Machines (Model : AIT-300-ASTM, AIT-300-ASTM-D).

FEATURES

For Charpy tests on various Materials
Strictly conforms to ASTM-E-23-2007 speficiations
Works on pendulum principle, difference between height of drop of pendulum before rupture and height of rise after rupture of specimen is direclty proportional to empact energy absorbed by specimen and is indicated by a pointer on a large dial for model: AIT-300-ASTM & on display for model: AIT-300-ASTM (D)
Single stand design which facilities fast and easy positioning and centering of specimen which is basic requirement of sub-zero testing
Unique spring loaded braking systems for smooth and jerk free braking
NIST approval of machine with samples from NIST-USA, can be arranged
Model: AIT-300-ASTM (D) is a digital version of model: AIT-300-ASTM

STANDARD ACCESSORIES

Charpy Striker – 1 no.
Charpy Support Block – 1 set.
Specimen setting gauge (for charpy) -1 no.
Set of spanners – 1 set.
Foundation braket – 1 no.

OPTIONAL ACCESSORIES

Self cetering tong for charpy test specimen (useful particularly for carrying out tests at sub zero temperature)
Sub zero temperature bath with digital temperature indicator
Go : No-Go gauges for confireming the following parameters of specimen within th limits specified by standard
a) Centre line of notch from both ends
b) Angle of V notch
c) Depth below standard V notch
d) Cross section of 10×10 mm specimen
Milling cutter for V notch
Charpy & Izod Notch (V & U) Broaching machines
Lateral expansion gauges as per ASTM-E-23
Standard Impact specimen for verification of machine from NIST, USA (We also undertake calibration of the machine as per ASTM-E-23 including approval from NIST – USA)
