1.1.1 Intended Use and Application Range
UK1401 Ultrasonic Testers are designed for measurements of time and propagation velocity of longitudinal ultrasonic
waves in solid materials when doing surface scanning on a rigid foundation in order to determine the strength and soundness
of materials and facilities.
The main application areas of the instruments:
- determination of concrete strength by the ultrasonic sound velocity according to GOST 17624 87;
- determination of concrete strength of the structures being in service along with the “separation with chopping off”
procedure;
- evaluation of the load carrying capacity of concrete supports and pillars made of centrifugally cast concrete based on the
relation of the ultrasonic sound propagation velocities in the directions along and across of the support axis.
Additional features:
- searching for near-surface defects in concrete structures by abnormal velocity decrease or increase of ultrasound
propagation time in the defective (unsound) spot/areas as compared to the areas without defects;
- evaluation of the depth of the cracks facing the concrete or stone surface;
- evaluation of the porosity and cracked structure of subsurface rock, anisotropy degree and structure of composite
materials;
- evaluation of the similarity or difference of elastic properties of the materials or samples of the same material as com-
pared to each other, as well as material age provided their properties change over a period of time.
Technical solutions used to produce the instruments, are protected by the Russian Federation Patent No. 2082163.
1.1.2 Operating Conditions
The instruments are designed for operation under the following conditions:
- ambient air temperature: from -20 to +50 ˚С;
- relative air humidity up to 95 % at + 35 ˚С.
