Near ultraviolet filter, английский
Device used to modify the emission spectrum from an ultraviolet radiation source by eliminating most visible light and high energy (far ultraviolet) radiation. nondestructive characterization (ndc): branch of nondestructive testing concerned with the description and prediction of material properties and behaviors of components and systems. nondestructive evaluation (nde): another term for nondestructive testing. in research and academic communities, the word evaluation is often preferred because it emphasizes interpretation by knowledgeable personnel. see also nondestructive examination; nondestructive inspection. nondestructive examination (nde): another term for nondestructive testing. in the utilities and nuclear industry, examination is sometimes preferred because testing can imply performance trials of pressure containment or power generation systems. nondestructive inspection (ndi): another term for nondestructive testing. in some industries (utilities, aviation), the word inspection often implies maintenance for a component that has been in service. nondestructive testing (ndt): determination of the physical condition of an object without affecting that object’s ability to fulfill its intended function. nondestructive testing techniques typically use a probing energy form to determine material properties or to indicate the presence of material discontinuities (surface, internal, or concealed). see also nondestructive evaluation; nondestructive examination; nondestructive inspection. o
