Measurement and the following features 40MHz medical ultrasound depicted; --- Part 2. 40MHz or less water ultrasound hydrophone calibration; Part --- Section 3. 40MHz or less water ultrasound hydrophone characteristics. This section YY/T Section 30865 of. This section drafted in accordance with GB/T 1.1-2009 given rules. This section is equivalent to using the International Electrotechnical Commission standard IEC 62127-3.2007 "ultrasonic hydrophone - Part 3. 40MHz or less Ultrasound hydrophone water features. " Correspondence between the consistency of the standards of international documents and normative references of the following documents. YY/T 0865.1-2011 ultrasonic hydrophone - Part 1. Measurement and characterization of medical ultrasonic fields of 40MHz or less portrayed (IEC 62127-1.2007, IDT) This part of IEC 62127-3.2007 only made a very small amount of editorial changes did not affect the degree of consistency. This part is proposed by the China Food and Drug Administration. This part of the standardization of medical ultrasound equipment for medical appliances National Standardization Technical Committee Technical Committee (SAC/TC10/SC2) Centralized. This section drafted by. State Food and Drug Administration of Hubei Medical Device Quality Supervision and Inspection Center. The main drafters of this section. Wang Zhijian, Jiang Shilin.IntroductionUsually miniature ultrasonic hydrophones measuring space and time ultrasonic liquid medium field sound pressure distribution, many of those involved in the IEC standard Hydrophone various aspects of the device characteristics. Objective YY/T 0865 of this section is. the sum of all these requirements, for hydrophone characteristics establish a Parts of common standards. The main application areas of this part of the hydrophone is. measuring ultrasonic fields in water by the medical diagnostic equipment emits. Other doctors Science application areas are. treatment equipment, such as crushed stone, high-intensity focused ultrasound (HIFU) and sound field measurements treatments. In non-medical applications, Hydrophone in product development and quality control and other aspects are also widely used, including. --- Ultrasonic cleaning tank super sound field depicted; --- In the emission measurement system, the use of the characteristics of the sound field rendering (for example, an ultrasonic spectrometer, ultrasonic attenuation meter and speedometer); --- In the reflection measurement system, used in depicting the characteristics of the sound field (for example, Doppler flow meter). At the same time, the term "hydrophone" more widely understood here relates to a miniature piezoelectric hydrophone. Currently this type of instrument, in Application of ultrasound in various fields, especially for quantitative medical diagnostic equipment sound field structure is depicted. Other types of pressure sensors, such as one based The principle of fiber, some of the requirements of this section apply, others do not apply. If in the future these other "hydrophone" type of sound field measurements Occupy a more important role in the revision of the standard or independent of this part will be related to their properties. Underwater acoustic hydrophone by the IEC 60500 and IEC 60565 covered, although there is overlap in the frequency range, but does not belong to this part of the Fan Domains. Underwater acoustic hydrophone for natural waters, even the ocean, which led to different technical concepts and requirements. In addition, the application of acoustic sound of water The main direction of the incident is generally perpendicular to the axis of acoustic hydrophone and assume in this section, which is located on the hydrophone axis. In the past, ultrasound hydrophones used almost exclusively amplitude sensor, the current situation has changed, even more attention to the use of their additional phase information, However, only during the calibration may be used to determine the phase characteristics when the hydrophone. Therefore, in this section, in addition to the provisions of the hydrophone Sensitivity margin requirements, but as an option, phase requirements are also suggested. Ultrasonic hydrophone Part 3. 40MHz of ultrasonic field water hydrophone characteristics1 ScopeYY/T 0865 this part of the provisions of the relevant hydrophone performance requirements. This section applies to. --- Piezoelectric sensor, designed for measuring ultrasonic pulse produced by the device and continuous wave ultrasonic field hydrophone; --- For measurements in the water hydrophone; --- Mating or mating preamplifier hydrophone.2 Normative referencesThe following documents for the application of this document is essential.

IEC 62127-1 and related definitions included in IEC 62127-2 apply to this section. 3.1 Directional response directionalresponse In the center designated by the reference plane at the specified frequency, hydrophone response relationship between the direction of propagation of acoustic waves in the plane of incidence Description, usually graphically represented. Note. See IEC 60565.2006. 3.2 Effective hydrophone radius effectivehydrophoneradius ah, ah3, ah6 The radius of the rigid element-receiving hydrophone, the angular width of their expected directional response function is equal to the observed angular width. Unit. m, m Note 1. The angular width of the directional response function below a specified value of the peak is determined to specify the value of 3dB and 6dB radius respectively ah3 and ah6 FIG. Note 2. The radius is usually a function of frequency, typical experimental data, see [1]. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of YY/T 0865.3-2013_English be delivered?Answer: Upon your order, we will start to translate YY/T 0865.3-2013_English as soon as possible, and keep you informed of the progress.
