Introduction
Ultrasonic nondestructive testing technique is the use of ultrasonic pulse and echo signals to detect and evaluate the internal structure of the material lattice or uneven distribution
defect. Various types of electronic equipment can produce ultrasonic pulse and echo signals.
This standard describes a method for detecting the ultrasonic detector with display performance characteristics. Although these methods can also be detected with higher frequency
Rate of ultrasonic detector, but these methods are best suited for detecting the nominal operating frequency range of 100kHz ~ 25MHz ultrasonic detector.
These recommended techniques for the detection of mass-produced industrial ultrasonic detector. When this standard study ultrasound detector can not serve
When a combination of electronic components as a whole be described, the ultrasonic detector can be part of each electrical properties were evaluated separately. Evaluation of the ultrasonic inspection
Each part of the measuring instrument should provide a description of the relevant parts of the assessment.
Implementation of these proposed rules allow more detailed instructions. To use the provisions of electronic instruments is the ability to effectively use these methods
Prerequisite. It recommends carefully selecting and determining detection method. If some application-independent parameters and expectations, may not be detected, for example,
For example, when using a single-stage alarm defect in the application it is possible and vertical linear independence, only on the basis of ultrasonic flaw detector display accurate detection of deep
Or the thickness of the horizontal linear only crucial.
Do not make recommendations or give imply shortest cycle assessment ultrasonic detector electrical properties. Measurement accuracy depends not only each parameter
Comprehensive accuracy in each electronic equipment (should be given in the technical specifications and calibration of these instruments in the report) but also on the various parts of the system
Readings for precision. Can be assumed that the vertical and horizontal reading error measurements measured by the ultrasonic detector for display
± 1mm.
In particular, these techniques and methods in this standard aims to achieve the following purposes.
a) measuring the performance characteristics of the various components of the ultrasonic detector;
b) Check and ensure that the various components of the ultrasonic detector in working life has stability;
c) select and specify the required ultrasonic detector inherent overall performance characteristics;
d) the same type of testing, so that the same parts or the same as the entire instrument interchangeability;
e) For the performance test results of different instruments and test source having a consistency and comparability to create the basic conditions.
NOTE. These methods are not suitable for this standard to exclude some or all of measurement technology ultrasonic testing equipment use or application. In addition, this standard does not
It is not suitable for ultrasonic testing system as defined performance specifications. If you need to request performance of the system, it is desirable that the relevant parties agree.
