Inspection uncertainty: The key element in nondestructive inspection
Nuclear Engineering and Design, 1977Abstract This paper identifies the inspection uncertainty, which is a measure of the difference between the size of imperfection that has a high probability of being passed and the size of imperfection that has a high probability of being rejected by an inspection, as the primary measure of an inspection method, rather than the inspection sensitivity

Nondestructive inspection of metal products
Metallurgist, 1982Considerable emphasis is currently being given to finding more reliable and quicker methods and equipment for nondestructive and statistical quality control in attempts to solve the problem of improving product quality. Modern methods of nondestructive inspection make it possible to detect surface and internal defects and decarbonization, as well as to

In-Situ Cracking for Nondestructive Inspection Process Validation
Practical Failure Analysis, 2001Work at the Idaho National Engineering and Environmental Laboratory (INEEL) includes efforts to weld steel storage containers. Producing repeatable high quality welds and assuring weld quality is paramount to this work. The nondestructive examination (NDE) method used to measure weld quality is the magnetic particle testing (MT) process since the ...

Reliability analysis with nondestructive inspection
Structural Safety, 1997Abstract Nondestructive inspection tools are commonly used to inspect structures or structural components with resistance deterioration due to defect size growth. The quality of the tools is mainly defined by the rate of detecting a defect with defect size s, ϱ(s), and the accuracy in sizing a detected defect.

7.9 Nondestructive Inspection of Composites
2018This chapter examines the role of radiography in guaranteeing a minimum quality in composite materials and structures. The chapter covers traditional film based radiography and the new solid-state radiography. Because traditional radiographic techniques are not applicable to composites, sections cover modifications necessary to enhance the contrast ...

Overview of Nondestructive Inspection Techniques
1974Numerous nondestructive inspection techniques are available today for the detection of flaws in a variety of materials including ceramics. The purpose of this paper is to present an overview of current NDT principles and techniques including criteria for the proper selection of effective test methods.

Ultrasonic nondestructive tubing inspection system
The Journal of the Acoustical Society of America, 1987A system for measuring the extent of tube wall erosion in an inspection region of a heat exchanger tube of a nuclear steam generator, uses an ultrasonic means driven helically inside the eroded tube which may be filled with a fluid (e.g., water) to minimize ultrasonic wave attenuation.
