Ultrasonics - Hydrophones - Part 1: Measurement and characterization of medical ultrasonic fields (IEC 62127-1:2022); German version EN IEC 62127-1:2022
Abstract
The main purpose of part 1 of IEC 62127 is to define various acoustic parameters that can be used to specify and characterize ultrasonic fields propagating in liquids, and, in particular, water using hydrophones. The philosophy behind this standard is the specification of the acoustic field in terms of acoustic pressure parameters, acoustic pressure being the primary measurement quantity when hydrophones are used to characterize the field. Moreover, measurement procedures are outlined that may be used to determine these parameters. Intensity parameters are specified in this standard, even though they are regarded as derived quantities that are meaningful only under certain assumptions related to the ultrasonic field being measured. Specific device related measurement standards, for example IEC 61689, IEC 61157, IEC 61847 or IEC 62359, can refer to this standard for appropriate acoustic parameters. In IEC 62359, some additional measurement methods are described addressing the specific needs of acoustic output characterization of ultrasonic diagnostic equipment in accordance with IEC 60601-2-37.
