O m\u00e1quina de teste de impacto com p\u00eandulo de filme<\/strong> is a precision instrument used to evaluate the impact resistance<\/strong> of plastic films, foils, and thin sheets. It is an essential tool in packaging, food, medical, and materials research industries. By replicating dynamic loading conditions similar to real-world impacts, this tester helps assess a material’s durability and toughness.<\/p>\n When films are used in packaging or product protection, understanding their resistance to sudden forces is critical. This is where the m\u00e1quina de teste de impacto com p\u00eandulo de filme<\/strong> plays a vital role\u2014it simulates high-speed puncture and measures the energy required to rupture the material<\/strong>, offering reliable data for performance evaluation.<\/p>\n O Norma ASTM D3420<\/strong><\/a> test method is the internationally recognized standard for determining the pendulum impact resistance of plastic films. It provides detailed instructions to ensure accurate, repeatable, and comparable results across different testing environments.<\/p>\n This method involves striking a clamped film specimen with a pendulum head<\/strong> at a known velocity and energy level. The energy absorbed<\/strong> by the specimen, leading to rupture or puncture, is calculated from the pendulum\u2019s motion. The test uses two main procedures:<\/p>\n Each method suits different material types and testing setups. However, results from Procedure A and B are not interchangeable<\/strong>, as their sample sizes and head diameters yield different impact dynamics.<\/p>\n During the ASTM D3420 test:<\/p>\n Unlike some methods, no correction is made for the tiny fragments punctured, since their mass is negligible.<\/p>\n Manufactured by Cell Instruments Co., Ltd.<\/strong>, o PIT-01 film pendulum impact tester<\/strong> is built for full Conformidade com a norma ASTM D3420<\/strong>, offering accuracy<\/strong>, automation<\/strong>, e user convenience<\/strong>:<\/p>\nASTM D3420 for Film Pendulum Impact Resistance<\/h2>\n
