Radiographic, английский
Radiographic code, английский
A code for specifying minimum standards related to radiographic practices.
Radiographic contrast (rt), английский
Radiographic equivalence factor (rt), английский
The factor by which the thickness of material must be multiplied in order to determine what thickness of a standard material (often steel) will have the same absorption.
Radiographic exposure device (rt), английский
Radiographic film, английский
Radiographic film (rt), английский
Radiographic inspection, английский
Рентгенографический контроль
Radiographic inspection (rt), английский
The use of x-rays or nuclear radiation or both to detect discontinuities in material, and to present their images on a recording medium.
Radiographic interpretation (rt), английский
The identification of subsurface discontinuities indicated on the radiograph. the evaluation as to the acceptability or reject ability of the material is based upon the judicious application of the radiographic specifications and standards governing the material.
Radiographic paper (rt), английский
White paper coated on one side with emulsion, suitable for some purposes as an alternative to x-ray film.
Radiographic projection method (rt), английский
A method whereby image magnification is achieved by projection.
Radiographic qualification test, английский
A procedure for determining the optimum value of the d/t ratio, or the proper working distance of an x-ray tube or a radioactive source.
Radiographic quality level, английский
Radiographic quality level (rt), английский
An expression of the quality (sensitivity) of a radiograph in terms of an image quality indicator (penetrameter). when a standard hole-type penetrameter is used, quality level is stated as a-bt, where a is the penetrameter thickness, expressed as a percentage of the maximum thickness of the specimen, and b is the diameter of the smallest discernible hole, expressed as a multiple of penetrameter thickness, t. for example, the 3- 2t quality level means that the penetrameter thickness equals 3 percent of maximum specimen thickness, and the smallest discernible penetrameter hole has a diameter equal to twice the penetrameter thickness.
Radiographic radiographic definition (rt), английский
Radiographic range (rt), английский
Radiographic screen (rt), английский
Radiographic sensitivity (rt), английский
Radiographic technique (rt), английский
The selection of those radiographic factors such as kilovoltage, milliamperage, type of film and screen, distance, and exposure time to render the best possible radiographic sensitivity.
Fluorescent, английский
- Флуоресцирующий; флуоресцентный (о надписи)
- U-lamp a tubular lamp whose bulb has a 180° bend at the center,
- Having the property to produce fluorescence.
- The ability of certain materials to absorb energy and then immediately release that energy in the form of light

Leak testing (pt), английский
Method of applying penetrant to one surface and developer to the opposite side of a structure to detect flaws that extend entirely through the structure.
Vacuum melting, английский
Melting in a vacuum to prevent contamination from air, as well as to remove gases already dissolved in the metal; the solidification may also be carried out in a vacuum or at low pressure.
