Nondestructive testing (NDT) is any of a wide group of analysis techniques used in science and technology industry to evaluate the properties of a material, component or system without causing damage. [1]

2022年9月7日 · Non-destructive testing refers to the use of testing techniques that do not alter any of the properties of the tested product. These properties could be its strength, integrity, appearance, corrosion resistance, conductivity, wear resistance, toughness and so on.

ASTM's nondestructive testing standards provide guides for the appropriate methods and techniques used to detect and evaluate flaws in materials and objects without destroying the specimen at hand. Such tests include radiographic, ultrasonic, electromagnetic (eddy-current), X-ray, acoustic, and tomographic techniques.

Nondestructive evaluation (NDE) is the science of detecting flaws and imperfections in materials to ensure structural integrity. Nondestructive testing (NDT), sometimes referred to as nondestructive inspection (NDI), is the practice of finding defects.

换句话说，NDT 用于无损“测试”，而 NDI 用于“检查”，用于通过/失败判断。 术语 无损评估 (NDE) 也用于“评估”材料和产品。 如何在不破坏产品的情况下知道产品的状态？ 由于人类是生物，我们可以通过体温和呼吸系统的变化来了解他们的健康状况，但从外面无法判断金属和塑料上是否有细微的表面划痕或内部划痕。 因此，我们将肉眼看不到的微小表面划痕可视化，或从外部施加 超声波 、 X射线 、电、磁、热等能量，通过反应了解材料是否健康. 例如，在表面划痕的情况下，可 …

2024年12月20日 · Non-destructive testing (NDT) is a set of testing and analysis processes that evaluate the quality and structural integrity of a manufactured product. Factories and manufacturing plants commonly use NDT. However, some unexpected fields, such as medicine, have also found a use for it.

2020年2月26日 · Non-destructive testing (NDT) is an examination of components or workpieces for their quality and structure that does not damage or impair them. It is regulated in the international standard DIN EN ISO 9712 and is used in various industrial sectors such as plant engineering, mechanical engineering, steel, power plant or vehicle construction.

Rigorous NDT testing helps prevent catastrophic failures such as airplane and locomotive crashes, pipeline leaks and explosions, nuclear reactor failures, and ship disasters. NDT practitioners ensure product integrity and reliability, control manufacturing processes, lower production costs, and maintain a uniform quality level.

Nondestructive testing (NDT) is the process of testing or inspecting a material, component, or system without causing damage to the test subject. There are several varieties of nondestructive testing, including traditional ultrasonic flaw detection, phased …
