No.258-UTL Impact Tester (With Ultra Low Temp Refrigerating Machine)

Description

Low-Temperature Testing

Two Types of Low-Temperature Impact Testers

Impact testing can also be performed in low-temperature environments. The No.258-L allows testing between -35℃ to 60℃, while the No.258-UTL supports testing as low as-50℃ to 60℃. Please select the model that suits your desired testing temperature.

• Touchscreen Operation

  Basic Operation and Result Registration AvailableBasic operations are performed using the touchscreen. After the test, the impact value is automatically calculated based on the hammer lift-up angle.
  The test results can also be checked in the test results screen.

  Accurate Testing

  Testing Within the Low-Temperature ChamberImpact testing is performed inside the low-temperature chamber, ensuring accurate testing conditions without any change in the test environment. Testing inside the chamber also prevents sample scatter, making sample collection easier.

  Charpy Hammers 

  Standard	Potential Energy	Impact Velocity	Angle of Striking Edge	Radius of Striking Edge
  ISO/ JIS	0.5J	2.9m/s(±10%)	30±1°	2.0±0.5mm
  	1J
  	2J
  	4J
  	5J
  	7.5J	3.8m/s(±10%)
  	15J
  	25J
  ASTM	2.7-21.7J	3.46m/s	45±2°	3.17±0.12mm

  The characteristics of the Charpy hammers differ between the test standards as shown in the table above. In ISO and JIS standards, the hammer length changes according to the impact velocity. Therefore, the same hammer cannot be used to create, for example, a 4 J impact and 7.5 J impact. Two different hammers must be prepared.

  Izod Hammers 

  Standard	Potential Energy	Impact Velocity	Radius of Striking Edge
  ISO/ JIS	1J	3.5m/s(±10%)	0.8±0.2mm
  	2.75J
  	5.5J
  	11J
  	22J
  ASTM	2.7-21.7J	3.46m/s(3.5m/s)	0.8±0.2mm

  The same hammer is sometimes used between ISO (or JIS) and ASTM impact tests as the details of the hammers specified in the two standards are similar. However, to be precise, the shape of the striking edge differs between the standards as shown in the above image. Therefore, to conform to the test standards, hammers that match the test standard shall be used.

  ー	Parallelism between long axis of test sample and reference plane	±4/1000	ー
  R2	Radius of curvature of anvils	1±0.1 mm	3.17±0.12 mm
  θ2	Angle of taper of anvils	10±1 °	0

  ー	Angle of supports and anvils	90±0.1 °	90°
  L	Span between sample supports	62±(0.5/0) mm	101.6±0.5 mm

  The shape of the anvil differs between ISO (or JIS) and ASTM standards. Therefore, to perform both ISO and ASTM standardized tests, two different anvils shall be prepared.
