The Izod Test in the Class J - Charpy and Izod Automatic Impact Testing System follows the following standards and angles of striking:

• Standard: ISO 180, ASTM D256
• Angle of striking: 150° (ISO 180), 145.2° (ASTM D256)

The ISO 180 standard specifies the test method for plastic impact strength determination using the Izod test. In this test, the striking angle is set at 150°, which refers to the angle at which the pendulum strikes the specimen.

Similarly, the ASTM D256 standard also describes the test method for determining plastic impact resistance using the Izod test. However, in this case, the striking angle is slightly different, namely 145.2°.

A standard striking specification and speed defined by ISO 180 and ASTM D256 is followed when carrying out the Izod Test using the Class J - Charpy and Izod Automatic Impact Testing System.

In accordance with ISO 180, a standard that outlines the method for determining plastic impact strength through the Izod test is an international standard. In this test, the angle of impact is set at 150°, and the strike velocity is maintained at 3.5 m/s.

According to ASTM D256, the Izod test, developed by ASTMA for evaluating plastics' impact resistance, may also be used to evaluate plastic's impact resistance. The angle of strike in this standard differs slightly from the one in the previous standard, which is 145.2°, as well as the velocity of strike which is specified as 3.46 m/s.

The Class J - Charpy and Izod Automatic Impact Testing System for the Izod Test provides a specified distance from the axis of support to the center of percussion, which is measured at 335 mm. This distance is a critical parameter in the Izod Test as it determines the leverage and moment of the pendulum when it strikes during impact. By setting the distance to 335 mm, the testing system ensures consistent and reliable test results for assessing materials' impact resistance and strength.

The distance from the axis of support to the center of percussion is a critical factor in properly simulating real-world impact scenarios and evaluating materials' ability to withstand sudden external forces. It plays a significant role in determining the energy transfer and fracture behaviour of test specimens. Therefore, by maintaining a precise distance of 335 mm, the Class J - Charpy and Izod Automatic Impact Testing System ensures accurate and standardized Izod Test measurements.

The Class J - Charpy and Izod Automatic Impact Testing System for the Izod Test provides a specified distance from the striking knife center to the vice upper surface, which is measured at 22±0.2 mm. This distance is a crucial parameter in the Izod Test as it determines the position of the striking knife in relation to the vice upper surface during impact. By setting the distance to 22 mm with a tolerance of ±0.2 mm, the testing system ensures precise and consistent positioning for reliable test results.

The distance from the striking knife center to the vice upper surface is crucial for accurately aligning the test specimen and ensuring proper contact between the striking knife and the specimen during impact. It affects the transfer of energy and the resulting fracture behaviour, thus influencing the measured impact strength of the material. Therefore, maintaining a precise and specified distance of 22 mm is essential for conducting standardized and reliable Izod Tests.

The Class J - Charpy and Izod Automatic Impact Testing System for the Izod Test provides a specified radius of the striker edge, which is measured at 0.8±0.2 mm. This radius refers to the curvature of the striker edge used in the test. By setting the radius to 0.8 mm with a tolerance of ±0.2 mm, the testing system ensures consistency and accuracy in the impact test results.

The radius of the striker edge is an important parameter as it affects the way the striker contacts and interacts with the test specimen during impact. A precise and specified radius ensures that the force is applied uniformly and consistently across the specimen, leading to reliable and comparable test results. The radius also influences the stress concentration at the point of impact, which can affect fracture behaviour and the measured impact strength of the material.

Therefore, maintaining a specified radius of 0.8 mm with a tolerance of ±0.2 mm is crucial for conducting standardized Izod Tests and obtaining accurate and reliable impact test data.
