Summary This standard specifies the use of transmitting and receiving ultrasonic longitudinal wave pulse instrument. And using as the coupling agent and the liquid by the liquid immersion or spray techniques. To detect material discontinuity ultrasonic testing methods. This standard applies in an appropriate acoustic frequency conductivity, but also immersed in a liquid coupling agent is detected in the material, or can be detected between the probe and the material to be detected by controlling the coupling liquid column material or liquid.

Foreword

This revised standard adopts ASTME214-01 "immersed ultrasonic pulse longitudinal wave reflection detection method" (in English). This standard redrafted according ASTME214-01. Taking into account China's national conditions, when using ASTME214-01, we made some changes in this standard. About the technical differences are as follows. --- Increase Normative references GB/T 5616; --- The Normative references ANSTSNT-TC-1A, ASNTCP-189, NAS-410, MIL-STD-410 to our standard Quasi GB/T 9445; --- The Normative references ASTME1316 to our standard GB/T 12604.1 and GB/T 20737; --- The Normative references ASTME127 and ASTME428 instead of the standard GB/T 23905; --- Delete references to normative documents ASTME1001; --- Increased institutional requirements (see 4.3); --- Remove ASTME214-01 of 1.2,10.2,10.3 and Chapter 11. For ease of use, this standard also made the following editorial changes. --- "The method" be replaced by "this standard"; --- Insert GB/T 1.1-2000 specified key words in Chapter 2; --- According to GB/T 1.1-2000 format specified requirements of Chapter 1, Chapter 2, Section 5, Chapter 7, Chapter 8, and Chapter 9 Article 10 in Chapter part number has been modified.

1 Scope

This standard specifies the use of transmitting and receiving ultrasonic pulse longitudinal wave instrument, and using liquid as a coupling agent, and immersion or by spraying liquid Technology to detect material discontinuities ultrasonic testing method. This standard applies to the conduction in an appropriate frequency sound waves, but also immersed in the liquid coupling agent is detected in the material, or can probe and the subject By controlling the coupling between the material to detect the liquid column or liquid materials.

4 Overview

4.1 Qualification Staff by implementation of this standard test, should be GB/T 9445 or contractual parties agreed system for Qualification and certification by the employer Master or agent job professional training and authorization to operate. 4.2 Written procedures testing process Ultrasonic testing according to the standard implementation, should prepare detailed written testing process procedure (see GB/T 5616). Written procedures should be testing process This standard contains various elements, in order to ensure consistency and the detection result of the implementation of repeatability. For written testing process procedure Code Special requests written and approved by the parties to the contract should be clear in the agreement in. 4.3 Body requested According to the present embodiment standard testing agency or unit should be consistent with GB/T 5616 requirements or equivalent standards and regulations.

5 device

5.1 Electronic Equipment Electronic equipment should be able to generate, receive and display the desired electrical pulse frequency and energy, and A-scan display. Note. Other display mode, such as B-scan and C-scan, it can be used, but not covered by this standard. In the detection site, you should use the appropriate appliance regulator, thermometer and hygrometer, to ensure stable operation of the electronic device.
