The NG-ImpactFall, a falling weight impact tester, finds extensive application in conducting external impact strength tests on plastic pipes, plastic boards, and non-metal materials. Specifically designed for various types of plastic pipes, it accommodates PVC-U water supply pipes, low-pressure water supply pipes, core layer foam pipes, double-wall corrugated pipes, carat pipes, steel belt pipes, PE water supply pipes, MPP electric power pipes, hollow wall winding pipes, CPVC power pipes, among others.
To set up the NG-ImpactFall for testing, begin by placing the pipe or profile onto the workbench. Ensure the sample's upper surface aligns precisely with the lower edge of the photoelectric correlation system by adjusting its height. Next, select the appropriate hammer head and weight as per the test standard requirements, assembling the impact hammer accordingly. Adjust the electromagnetic absorb system's height and suspend the hammer in place.
Initiate the test sequence, allowing the hammer to freely descend from the predetermined height, impacting the sample. Examine the resulting rupture or lack thereof in the pipe or profile. If there's one or no rupture observed, it signifies that the pipe or profile meets the standard for impact resistance. However, if there are multiple ruptures, it indicates that the impact performance fails to meet the specified standard.

The automatic zero-point adjustment feature in the NG-ImpactFall models significantly streamlines impact testing setup, enhancing both precision and efficiency. This feature automatically aligns the specimen to the optimal starting position for the test, ensuring that each impact is delivered accurately to the designated area. By eliminating manual adjustments, this automated calibration reduces setup time and human error, ensuring a consistent starting point for every test.
This precise alignment is crucial for reliable and repeatable test results, as even slight variations in specimen positioning can affect test results. The automatic zero-point adjustment ensures that each specimen is positioned correctly about the impact device, maximizing the test results' accuracy. This level of precision is particularly critical when testing materials to strict industry standards or when comparing the impact resistance of different materials under identical conditions.
The NG-ImpactFall models utilize a pneumatically operated system designed to prevent secondary impacts during testing, significantly enhancing results' reliability and accuracy. This system employs pneumatic mechanisms to quickly retract the impactor after it strikes the specimen, ensuring that it does not contact the specimen a second time as it might naturally do if left to bounce. Secondary impacts can skew results by introducing additional, unintended damage to the specimen. This would not accurately reflect the material's resistance to a single impact event.
By eliminating the possibility of these secondary impacts, the pneumatically operated system ensures that each test measures only the effect of a single, controlled impact, as intended by the testing standards. This precision is crucial for obtaining consistent and reliable data, particularly when assessing materials for critical applications where impact resistance is a key performance indicator. The enhanced control over the testing process provided by this system contributes to more dependable outcomes. This facilitates better decision-making in material selection, quality control, and product development based on accurate assessments of material durability and safety.
