The standard adopted by the United States to redraft the law to modify the standard ASTME2491-06 "phased array ultrasonic detector and system performance characteristics Evaluation". This standard compared with ASTME2491-06 made the following technical corrections. --- Table G.1 "report linearity correction table" corresponding data "linear amplitude control" in the first line of a paragraph 7 of the original 40, and G4.7 Test Description "100% amplitude adjustment signal to" inconsistent, according to the test described in this standard G4.7 is changed to 100. This standard also made the following editorial changes. --- Standard name was changed to "non-destructive inspection equipment performance and phased array ultrasonic testing system"; --- Deleted ASTME2491-06 foreword, and re-write the foreword; --- Use the "standard" instead of the word "this guide"; --- Amend the introductory phrase in Chapter 2, "Normative references" in; --- Chapter 2, "Normative references" added GB/T 12604.1-2005 "Terminology for nondestructive testing Ultrasonic testing", delete In addition ASTME1316 "Terminology for nondestructive testing"; --- Delete Chapter VII of the keyword feature, focus, phased array, phased array probes, beam profile, ultrasound. --- The normative appendices are numbered from A1 to A7 modify A to G. The standard proposed by China Machinery Industry Federation. This standard by the National Testing Machine Standardization Technical Committee (SAC/TC122) centralized. This standard is mainly drafted by. Shantou Institute of Ultrasonic Instruments Co., Ltd., Nantong Union Digital Technology Development Co., Ltd., Shenzhen, China Testing International Corporation, Wuhan Branch Innovation and Technology Co., Ltd., Liaoning Instrument Research Institute, Shantou Ultrasonic Electronics shares Ltd.

NDT phased array ultrasonic testing equipment Performance and inspection system1 Scope1.1 standard specifies the method for the evaluation of phased array ultrasonic detector and system performance characteristics. 1.2 Evaluation of the performance of these aims compare phased array ultrasonic detector and system, or through regular performance evaluation, detecting a specific phase Long-term changes in phased array ultrasonic detector or system performance, evaluate these changes, it is possible to identify potential phased array ultrasonic detector and systems Barrier, and once these changes exceed certain limit, we need to correct maintenance. This standard is based on the ultrasonic detection size of the role played by the relevant It highlighted the need to measure the project. The electrical characteristics similar to other aspects of performance and non-phased array means, in accordance with ASTME1065 "Characteristics of Ultrasonic Evaluation Guide" or ASTME1324 "ultrasonic testing instrument for some electronic characteristic measurement Guide" described measurements. 1.3 This standard can be used to evaluate the use of pulse wave trains and A-Scan display (RF or video) of the ultrasonic testing system. Alarm 1.4 standard can be used to evaluate the integrity of the testing system comprises a probe, phased array ultrasonic detector, coupler, scanning devices, connected And auxiliary equipment, was used to assess the use of the system without changing the case of replacement or duplicate test performance. This standard is not suitable as replacements Phased Array Ultrasonic calibration or standardized procedures or detector system to check for a specific material is carried out. 1.5 standard does not set the test system performance requirements. For such acceptance criteria, to be designated by the consumer. If the text relates to inspection Acceptance criteria, do illustrative purposes only, and always strictly limited customers and end users control file required. 1.6 needs to evaluate specific parameters, conditions and frequency of testing and reporting requirements of the data by the user decide. 1.7 In addition to the phased array ultrasonic testing devices or systems need to be evaluated, the required equipment also includes a test specimen and position encoders. 1.8 standard also includes procedures related to the applicability and interpretation of results Notes. 1.9 Only the customer agrees, can use alternative procedures, such as the example described in this document. Subject 1.10 standard is not intended to solve all the security problems associated with its use. Responsibility of the user of this standard to establish appropriate safety Whole and healthy practices, prior to use to determine the applicability of restrictions.2 Normative referencesThe following documents for the application of this document is essential.
