Izod impact strength test - Wikipedia
The Izod impact strength test is an ASTM standard method of determining the impact resistance of materials. A pivoting arm is raised to a specific height (constant potential energy) and then released. The arm swings down hitting a notched sample, breaking the specimen.
抗冲击强度 - 百度百科
抗冲击强度可直接反映、评价或判断一种材料（或者产品）的抵抗冲击能力（脆性、韧性程度），业界比较流行用三种方法：简支梁冲击（也称Charpy冲击）、悬臂梁冲击（也称Izod冲击）和落球（或者落锤）冲击。
ASTM D256塑料悬臂梁缺口冲击试验 - ZwickRoell Materials Testing
符合 ASTM D256 标准的悬臂梁缺口冲击试验将以厚度相关能量值的形式生成高应变速率下 抗冲击性 和缺口敏感性的特性值。 该试验通常在ASTM D618规定的23° / 50%相对湿度的正常气候下进行。 悬臂梁缺口冲击试验还将以仪器化试验的形式进行，即使用快速力测量方法。 不过，尚无此方面的标准。 所有塑料均可采用符合ASTM D256标准的悬臂梁缺口冲击试验来表征冲击应力导致的行为。 弯曲冲击应力采用摆锤刀口向前冲击的方式，施加在一端夹紧的缺口试样上。 结果以 …
Toughness of Plastic Materials: Notched Izod Impact Test
The two most common methods to determine toughness include: Izod and Charpy Test. measuring the amount of energy absorbed (Kg/m or Joule) in breaking the sample due to impact. The maximum energy content of the pendulum that hits the sample during the test.
Izod Impact (Notched) ASTM D256, ISO 180 - Intertek
Notched Izod Impact is a single point test that measures a materials resistance to impact from a swinging pendulum. Izod impact is defined as the kinetic energy needed to initiate fracture and continue the fracture until the specimen is broken. Izod specimens are notched to prevent deformation of the specimen upon impact.
Izod Impact Strength Testing of Plastics - MatWeb
Izod impact tests are commonly run at low temperatures - down to -40°F (-40°C) or occasionally lower - to help gauge the impact resistance of plastics used in cold environments. The impact resistance of a specific commercial grade of polymer is a function of the base resin plus the presence of any impact modifiers (such as elastomers) and ...
Izod Impact - an overview | ScienceDirect Topics
Izod impact measures energy required to break a specimen by striking a specific size bar with a pendulum. Izod normally refers to a notched specimen impact. However, in some circumstances, unnotched specimens are tested. The data sheet will note that it is an unnotched bar or unnotched Izod.
