No Interruption for Hammer Replacement
Automatic Charpy Hammer Switching (3 Capacities)Three types of Charpy hammers can be automatically switched without interrupting the testing process. Even when switching between hammers with different capacities, tests can proceed continuously, significantly improving testing efficiency.
*Not compatible with Izod testing. -
Automatic Sample Dimension Measurement
Significantly Reduces WorkloadThis function automatically measures the sample dimensions, eliminating the need for manual measurement and input. After measuring the dimensions, the sample is automatically set at the testing position. The process from measuring the sample dimensions to aligning the notch position is completed in approximately 5 seconds.

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.
| Standard | Potential Energy | Impact Velocity | Radius of Striking Edge |
|---|---|---|---|
| ISO/ JIS |
1J | 3.5m/s(±10%) | 0.8±0.2mm |
| 2.75J | |||
| 5.5J | |||

| 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.

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.
| Symbol | Parameter | ISO/JIS | ASTM |
|---|---|---|---|
| ー | Sample angle | 90±2 ° | ー |
| ー | Parallelism with face of reference sample | ±0.025 mm | ー |

| R2 | Top edge radius of support | 0.2±0.1 mm | 0.25±0.12 mm |
In strict terms the anvil shapes differ between ISO (JIS) and ASTM standards, but are sometimes used mutually as the differences are minor.
This function automatically measures the dimensions of the sample, eliminating the need for manual measurement and input, thereby significantly reducing workload.
This function allows for the automatic switching between three hammer capacities. Even when hammers with different capacities are used, the tests can be proceeded continuously without interruptions caused by hammer replacement.
This function automatically collects tested samples. By selecting the desired samples on the PC software, they are automatically retrieved after impact. This is particularly useful when samples need to be inspected after testing.
Adjusts the height of the hammer when using hammers of different lengths.
Equipped with a built-in low-temperature chamber, this function supports testing at temperatures as low as -35℃.
