The impact energy, measured when a hammer strikes the sample, determines the material&#8217;s impact strength.The testing methods include the Charpy Impact Test and Izod Impact Test. The Charpy Impact Test is where the sample is supported at both ends and struck on the back of the notched section, and the Izod Impact Test is where one end of the sample is fixed, and the other end is struck from the notched side.<br>The 258 Series offers four models to provide optimal solutions tailored to specific customer needs. All models are designed and manufactured in compliance with industrial standards such as JIS, ISO, and ASTM.<br>Additionally, the entire series prioritizes usability and safety. The high-end model, No.258-ZA Impact Tester (Full Automatic),  completely automates the testing process, bringing efficiency and accuracy to a totally new level in quality assurance and research &#038; development environments.<\/p>\n        <p class=\"inner-contents\"><a href=\"https:\/\/yasudaseiki.com\/en-test\/impact-test\/\">Learn more about impact testing here<\/a><\/p>\n    <\/div>\n    <div class=\"series-overview-item series-section-inner\">\n        <h2 class=\"products-h2\">Reference Standards<\/h2>\n        <div class=\"products-standard\">\n            <ul class=\"products-standard-list\">\n                <li>JIS K 7111-1, K 7110, B 7739<\/li>\n                <li>ISO 179-1, 180, 13802<\/li>\n                <li>ASTM D256, D6110<\/li>\n            <\/ul>\n        <\/div>\n        <p class=\"products-annotation-strong\">*This product is designed for plastic impact testing; it is not compatible with metal samples.<\/p>\n    <\/div>\n    <div class=\"series-overview-item series-section-inner\">\n        <div class=\"series-features\">\n            <h2 class=\"series-features-h2\">Key Features of the 258 Series<\/h2>\n            <ul class=\"series-features-list\">\n                <li>\n                    <div class=\"series-features-list-inner\">\n                        <div class=\"series-features-list-inner-text\">\n                            <h3 class=\"series-h3\">Versatile Test Compatibility<\/h3>\n                            <p>By replacing the hammer and anvil, the tester can be used to perform both Charpy and Izod impact tests accordingly.
